Why Replace Engine Seals During a Rebuild?

When rebuilding an RB engine, replacing ageing seals and gaskets is one of the most cost-effective ways to improve long-term reliability.

A leaking crank seal, rear main seal, cam seal or oil pump gasket can quickly contaminate a new clutch, reduce oil control and create unnecessary downtime. Replacing these components while the engine is apart helps ensure years of reliable service.
