Toyota 3B Engine Rebuild Kit for 3 & 5 bearing cam engines up to 07/1988

Engine Kit prices may be subject to change without notice.

Please read the information contained below here carefully for important information.
• There are upgraded parts that can be added to your order - these are listed at the bottom of this listing.

Note: This kit can be made-up to suit either 3 or 5 bearing cam engines from 1981 model years to 07/1988 (Canadian market spec.).

This is a kit that can be "mixed and matched" with the different main bearings and cam bearings to suit either an early or later 3B with cylinder liners. 3B engines that lack cylinder liners are called "Parent Bore" and require a different kit, please enquire.

Please supply clear information about which bearing specifications you need included with the kit as far as undersizes or oversizes go. Typically this will be provided to you by your machinist after a tear down and inspection of your engine.

Please supply clear information about which cam bearings you require - either 3 bearings or 5 bearings - and their sizing.

Also, carefully read the list of additional suggested parts below the kit contents listing.

The bearings can come in sizes other than standard. The engine being rebuilt should be measured by a machine shop for parts sizing before the kit is ordered.

The head gaskets that come in the kits are composite, and work very well if the block and head surfaces are properly prepared and cleaned. They are not designed for turbo charged engines, but do handle turbos reasonably well. If you want run more than moderate levels of boost, you should upgrade to an MLS gasket.

MLS head gaskets (1115-58110) are available as an option (see suggested items, below), but the block and head surfaces need to be machined to the correct RA (Roughness Average) to allow these gaskets to seat properly. Speak with your machine shop, an RA of 20-30 is generally correct.

MLS exhaust manifold gaskets (17173-58010-MLS) are available as an option (see suggested items, below). These are recommended if you are using a turbo. Non-coated MLS exhaust gaskets can generally be re-used several times.

Composite Intake Manifold gasket (17171-56010) the standard gasket is treated paper, and thin - it's fine if you are running a stock rebuild. However, If you are going to be adding a turbo, you should upgrade to the improved Genuine Toyota composite intake gasket to get better sealing against boost leaks.

Head Bolt length should be carefully checked against the stack height of the head + compressed gasket + bolt seating depth in the block. Very old, pitted, or rusty head bolts should be replaced.

These items DO NOT come in the kit:
• Head Bolts
Pre-combustion chambers
Injector Seal Kit
