Engine Repair Gasket Kit

The Fel-Pro BS40626 Rear Main Gasket Set provides the seals required to service the rear main bearing area on compatible engines. It is intended for technicians and experienced DIYers performing a rear main seal replacement. The kit gathers the necessary components into a single package for that specific repair job.

Transparent Material Identification

The gaskets are moulded in a transparent colour so the installer can visually confirm seating and alignment during assembly. This visibility helps prevent mis-installation that could lead to oil leaks after the engine is reassembled. The material is designed to withstand normal engine operating temperatures and fluids.

Rear Main Seal Replacement Solution

This set replaces the original rear main gasket components when they have hardened, shrunk or begun to leak. The upgrade is worthwhile when an engine shows oil seepage at the rear main area or during a clutch, flywheel or transmission removal that exposes the seal. It is not suited for front main seal work or complete engine overhauls that require a full gasket set.

Questions about this item

Which engine interface does the Fel-Pro BS40626 gasket set seal, and what leak path does it cap?

The set seals the rear main bearing cap on the crankshaft, closing the oil leak path between the block and crankshaft rear journal.

What physical clearance does the Fel-Pro BS40626 set need to fit inside the block?

It installs in the rear main cap groove and block saddle; the split-ring halves must sit flush with the parting line and register in the dowel slots.

How is the Fel-Pro BS40626 set installed, and which step is most often done wrong?

Clean both sealing surfaces, coat the lips with fresh engine oil, press each half into its groove without stretching, then torque the main cap to spec — skipping the oil coat or stretching the seal causes leaks.
