Oil seal Large is a hard-part engine component: it takes part in combustion, sealing or guiding the moving parts.
Assembly matters as much as the part: tolerances, torque and a clean bore decide whether the replacement lasts. Any internal work should be closed out with new oil and filter.
Specifications and compatibility
This item is supplied against the equipment reference; confirm the application from the set nameplate before ordering.
How to verify before ordering
- Match the reference stamped on the part and the nominal or oversize dimension the engine needs.
- Check the engine serial range it belongs to; the same model can use two variants.
- Order the full gasket set and new head bolts where the job requires them: they are not reused.
Frequently asked questions
Can a single liner be replaced?
Technically yes, in practice the full set is changed. One new cylinder beside worn ones unbalances the engine and forces a second teardown.
How do I know I need an oversize?
By measuring bore or journal wear before ordering. Without that measurement the part may not seat and the job repeats.
