Hi All,

My Focus got an oil leak and my father-in-law located the problem as the crankshaft pulley. He changed the seal twice to no avail, then replaced the pulley and then another seal in the new pulley. Each time he has replaced the seal or pulley the oil leak has returned...

When test driving it, the crankcase breather hose was removed to check it wasnt pressurising but still, an oil leak returns.

Has anybody come across this problem before (or similar) and can pass on any advice?

Many thanks,

Andy
