Engine$aver Parts®

Fel-Pro® are proven to make technicians’ lives easier. But gaskets are just a part of the total engine repair and leak repair environment! Other products come into play as well, such as those in the Engine$aver® line. This product line includes anything that has to do with engine assembly and disassembly. Engine$aver products are specifically designed to help technicians perform specific tasks more quickly and easily. These specialty engine repair and leak repair components fall into three categories:

Replacement – Many engine parts must be replaced for complete, quality engine work. The replacement of such parts like dowel pins and head bolts can make the difference between customer satisfaction and an expensive comeback.Repair – At times it’s more efficient to repair, rather than replace, a part. This is especially true of expensive engine parts like crankshafts.Installation Aids – These parts and tools speed the job of replacing gaskets.

Head BoltsMost manufacturers recommend that new head bolts be installed whenever the cylinder head is removed because the old bolts stretch as a result of torque-to-angle tightening. New head bolts offer the most consistent clamping force possible between the head and block. Reusing old bolts isn’t a good idea – they may not provide enough clamping force and they can break while being torqued. To help eliminate comeback repairs, OEM specs should be followed.

Fel-Pro offers a complete line of head bolts, including Torque-To-Yield Head Bolts (covered in the Engine Repair section). Fel-Pro Head Bolts, when installed new, assure the most consistent clamping force possible between the head and the block.

Head Gasket Spacer ShimsWhy they may be needed: Machining of cylinder headsIt is often necessary to machine a cylinder head in order to provide a surface smooth enough for sealing or to bring an out-of-flat head back into specifications. The amount of metal removed depends on the condition of the head. If warpage is severe or if the head has been surface-ground several times, enough material may have been removed to cause problems. Removing too much metal from the head can:• Raise the compression ratio enough to cause

serious detonation problems, which result in engine damage

• Retard overhead camshaft timing enough to affect engine performance

• Cause mechanical interference between valve heads and piston tops

HeadSaver® Spacer Shims solve the problemBuying and installing new cylinder heads is one solution to this problem – and an expensive one. Another is to use a Fel-Pro® HeadSaver® spacer shim at a fraction of the cost of a new head. Installed between the block and a Fel-Pro head gasket, these .020” thick, dead-soft copper shims serve as a replacement for the machined-away material. This restores proper compression ratios, restores valvetrain geometry in overhead cam engines, and can eliminate potential mechanical interference between engine components.

NOTE: A HeadSaver spacer shim is NEVER used by itself – only with a Fel-Pro head gasket!

Where do I find spacer shims in the catalog?Whenever Spacer Shims are available, they will be listed in the Cylinder Head section of the Fel-Pro catalog, below the standard head gasket number.

Repair Sleeves – Crankshaft Why they may be needed: Crankshaft grooves at the rear main bearing seal areaAlthough rear main bearing seals are softer than the steel parts they contact, dirt and other abrasive debris can collect under the seal lip area and cause a groove to wear into the crankshaft. This is especially important on vehicles with a manual transmission. The result is a leaky rear main seal. Simply installing a new seal may not correct the leak. The technician’s choices include:• Paying hundreds of dollars for a new crankshaft

• Welding and remachining the crankshaft sealing surface area

• Attempting to move the seal to a different position on the shaft

These alternatives are either too expensive, too time-consuming or too risky to make them attractive.

Crankshaft Repair Sleeves are the answerBy installing a Crankshaft Repair Sleeve, technicians can keep the repair cost low, get the vehicle running again quickly, and still provide an effective seal. It’s an approach that’s sure to be popular with customers dealing with price- conscious consumers. A complete line of correctly sized installation tools is also available to make crankshaft repair sleeves easier to press into place quickly and accurately. The correct tool is listed with the repair sleeve for each application in the Fel-Pro catalog. Look in the section that lists Rear Main Bearing (BS) Sets. When a crankshaft repair sleeve is available, it will be listed along with the proper installation tool. The contents label on the repair sleeve box also lists the correct installation tool to use.

Worn Groove

Repair Sleeves – Harmonic BalancerWhy they may be needed: Harmonic balancer grooves at the timing cover seal areaThe front crankshaft oil seal is usually located in the timing cover, and seals against the shaft of the harmonic balancer (also called the vibration damper). The abrasive action of dust and dirt that gets under the oil seal can wear a groove in the shaft (or hub). Unless the groove is corrected or repaired when the seal is replaced, leakage may occur.

To correct this problem, the technician’s choices include:• Replacing the harmonic balancer

• Welding and remachining the shaft sealing surface area

• Taking a chance on repositioning the oil seal at a different location on the shaft

None of these options are desirable. Replacement of the balancer is costly. Welding and remachining the shaft is time-consuming and costly. Repositioning the oil seal runs the risk of a continuing leak and a costly comeback repair.

Fel-Pro® Sleeve ’N’ Seal® The Fel-Pro sealing solution is Sleeve ’N’ Seal® – a thin, precision-made, durable repair sleeve that easily press-fits over the grooved shaft to provide a smooth surface for the seal lip to contact. (Then a standard oil seal can be installed for a secure, leak-free seal.) A complete line of correctly sized installation tools is also available to make harmonic balancer repair sleeves press into place quickly and accurately. The recommended Sleeve ’N’ Seal and the appropriate tool to use are listed in the catalog in the Timing Cover listing.

Oil Pan SnapUps®

Why they may be needed: Correctly positioning the oil pan and its gasket is difficult when an engine is still in the vehicle. It is often a time-consuming and frustrating exercise to install an oil pan while holding the gaskets in place at the same time. If the oil pan and gasket are not properly aligned during installation, oil leakage is likely after the job is done.

Fel-Pro® engineers have come up with an oil pan installation aid unequalled in the marketplace today. The Fel-Pro line includes Oil Pan SnapUps,® designed to hold up the pan and gaskets, and allow for quick, convenient bolt installation.

SnapUps oil pan installation aids are sold in engine sets for the most popular 5/16” (P/N ES 72863), 6mm (P/N ES 72864), and 8mm (P/N ES 72865) bolt applications and are reusable.

SnapUps are included with premium PermaDryPlus® oil pan gasket sets.

Load Spreaders®

Why they may be needed: Distorted valve cover flangesOn certain General Motors V6 and V8 engines, valve cover flanges tend to distort at the bolt holes. This presents a serious problem when trying to install a new valve cover gasket. Tightening the bolts often fails to achieve a secure seal because distortion of the flange results in low or uneven clamping force.

This problem was aggravated on certain vehicles where RTV sealer was used in place of gaskets and used valve covers of thinner gauge steel.

Worn Groove

Sleeve ’N’ Seal is sold separately and also with a Timing Cover Set (TCS)

Load Spreaders® (con’t.)RTV is not a recommended solution for aftermarket sealing on these applications. Instead, technicians should use gaskets. But because the thin valve covers are particularly subject to distortion, clamping force isn’t always even and leaks may result. An alternative to purchasing and installing a new valve cover is using Load Spreaders.®

Load Spreaders distribute the clamping force more evenly on the valve cover flange. This results in a better seal between the valve cover and the head – for just a fraction of the cost of a new valve cover. Load Spreaders install quickly and easily. Each Load Spreader set includes four pieces and will service one valve cover.

How to find Load SpreadersWhere available, Load Spreaders are found in the Valve Cover (VS) Set section of the Fel-Pro® catalog. Please note that each Load Spreader set services ONE valve cover on an engine.

Cylinder Head Dowel PinsWhy they are needed: Cylinder head dowel pins or pilot sleeves often become damaged during engine service or machiningInstalling the head gasket on the damaged dowels, or without the pilots in place, can risk improper alignment of the gasket and cylinder head-to-engine block assembly. This can result in gasket leakage or mechanical engine damage. Fel-Pro offers cylinder head alignment dowel pins or pilot sleeves to assure proper gasket and casting alignment for an accurate seal and trouble-free engine operation.

Exhaust SpringsWhy they are needed: Weakened exhaust springs can lead to leaksThermal expansion and contraction of the exhaust system can fatigue exhaust flange bolt springs and cause exhaust leaks. The bolts can become corroded and the bolt threads can become poorly defined, losing strength and clamping force. If worn bolts and springs are reused, they can cause possible failure during assembly.

Fel-Pro Exhaust Flange Bolt & Spring Kits ensure a tight exhaust flange seal at the pipe joint. These kits are complete assemblies for one joint, including two bolts or studs, two springs and two nuts (where required). These are all the pieces needed to complete the job and guarantee a leak-proof seal.

Leak Repair Gaskets

Sealing Leaks Avoids DamageGaskets sealing drivetrain components are typically neglected. But as these components leak, the loss of fluid causes irreparable damage. In most cases, these gaskets need to be replaced when the fluids in the drivetrain components are replaced. This is especially true for differentials and transmissions.

Automatic Transmission Pan Gaskets (TOS)Fel-Pro® A/T pan gaskets are manufactured of Fel-CoPrene,® a synthetic rubber that is tough, durable and oil resistant. It resists crushing and extruding and is very conformable. That’s important because many transmission drain pans have dimpled or deformed flanges.

Installing an automatic transmission pan gasket can be frustrating and time-consuming because it is hard to hold the gasket in place while raising the pan to the vehicle. Fel-Pro A/T pan gaskets use the exclusive Hole-Locks® design to speed installation and provide a more effective seal. Bolt holes in the gasket are made just slightly smaller than the bolts themselves. This holds the gasket and bolts in place as the pan is raised to the vehicle. This feature also eliminates the need to use contact adhesive on the pan gasket, which could damage the transmission if it gets inside the casing.

Differential Cover Gaskets (RDS)Fel-Pro offers a complete line of pre-cut differential cover gaskets. They are the perfect replacement for gaskets that are leaking or are being replaced due to a change of fluids, or for applications previously sealed with RTV. They are constructed of proprietary Blue Stripe® paper material, and are enhanced with Printoseal® sealing beads if the application requires added sealing assurance.

Axle Flange GasketsA range of axle flange gaskets is available from Fel-Pro. These gaskets are used between the axle flange and the brake backing plate or differential housing to keep fluid in and contaminants out. They are usually replaced when differential service is performed. Fel-Pro axle flange gaskets are made of either:

• Proprietary paper material, or

• Thin, embossed steel

Sealing Pesky LeaksCooling system gaskets consist of:

Water outlet and thermostat gaskets

Water pump gaskets

(Since water outlet and thermostat gaskets are more often replaced – and more pesky leakers – a specific page is devoted to them in the Leak Repair section.)

Water pump gaskets should be replaced when the water pump is being serviced. This gasket is included in many Timing Cover Sets, but is also available separately. It is typically made of proprietary Blue Stripe® paper material and listed separately in the Master Catalog.

A Key Component for DriveabilityFuel System gaskets are an important asset to proper engine function. Their failure can lead to an improper fuel mixture, poor fuel mileage, and driveability problems including stalling, hesitation, rough idle, and emission control malfunctions. In today’s vehicles with closed-loop engine management systems, a leaky fuel system gasket can trigger MIL (Malfunction Indicator Light) illumination.

Fel-Pro® offers a full range of fuel system gaskets that include:

Carburetor mounting gaskets This gasket goes between the carburetor and the intake manifold. Fel-Pro carburetor gaskets are typically made of a special fuel-resistant material.

Air Cleaner GasketsThough no longer common, air cleaner gaskets ensure a leak-free seal between the air cleaner and the carburetor for proper emission control.

Throttle Body gasketsThrottle Body (or TBI) gaskets are popular replacement items. They are located between the throttle body assembly and the intake plenum on electronic (EFI) and multi-port (MFI) fuel injection systems. As these late-model applications age, they may require throttle-body replacement or repair, and a new gasket will be needed. Or possibly the original throttle body gasket will fail, causing driveability and emissions problems. Fel-Pro Throttle Body gaskets are the perfect gaskets for these applications and can be found in the Master Catalog.

Fuel Injector O-RingsFel-Pro fuel injector O-rings provide the proper air-tight seal between the fuel injector and the intake manifold. Virtually every vehicle on the road today is equipped with these types of seals. Their replacement may be required due to age-related failure, or they may be replaced during fuel injector service. Fel-Pro fuel injector O-rings provide the proper sealing technology for these applications.

Keeping Noise and Gases Under WrapsWhile an exhaust system leak doesn’t involve fluids, it can cause excessive noise or allow exhaust gases to enter the vehicle. To deal with this annoying and potentially hazardous situation, Fel-Pro® offers a full line of exhaust leak repair products. This product offering includes:

Exhaust Flange Bolt & Spring KitsUsually located at a pipe-to-manifold joint or muffler assembly-to-pipe joint, Fel-Pro exhaust bolt & spring kits assure correct clamping force and allow for engine movement.

Thermal expansion and contraction of the exhaust system can fatigue exhaust flange bolt springs and cause exhaust leaks. The bolts can become corroded and the bolt threads can become poorly defined, losing strength and clamping force. If worn bolts and springs are reused, they can cause possible failure during assembly. Fel-Pro exhaust flange bolt & spring kits ensure a tight exhaust flange seal at the pipe joint. These kits are complete assemblies for one joint, including two bolts or studs, two springs and two nuts (where required). These are all the pieces one needs need to complete the job and guarantee a leak-proof seal.

Exhaust Pipe GasketsFel-Pro offers a wide variety of exhaust flange gaskets. These include flexible expanded graphite packing gaskets (that keep a tight seal, even with engine movement, on pipe-to-manifold joints) and graphite-faced steel core gaskets for flange-to-flange connections.

EGR gasketsAn important component for controlling emissions, the EGR (Exhaust Gas Recirculation valve) reduces smog by sending exhaust blow-by gases into the intake manifold where they are burned in the combustion process. A leaking EGR gasket can allow exhaust gases into the engine compartment and unwanted air into the intake manifold. Replacement of this gasket is necessary during EGR service.

Fel-Pro makes these vital gaskets available for a broad range of vehicles. They are listed in the application section in the Master Catalog.
