Frequently Asked Questions

Should I replace this with the timing belt?

Yes. The crank seal sits behind the timing area, so do it while the belt is off to keep oil off a fresh belt.

How do I know the crank seal is leaking?

Look for oil at the front of the engine around the crank pulley and oil on the timing cover or belt. A wet, oily timing area means the crank seal is weeping.

Where does the crank seal sit?

It sits at the front of the crankshaft behind the timing area, which is why you fit it during timing belt work.
