Hi

Been holding this one off since the new year due to poor weather at weekends for a couple of month, had no excuse today to investigate the bad oil leak which has had the car parked up. :cry:

Looks to be coming from the crankshaft pulley. :thumbsdown:

Has anyone come across this before?

With the engine in this is going to be a bit tricky for clearance but yes looks like crank seal :thumbsup: getting something big enough diameter to tap it in should be the only issue after you get the pulley off which i think is a 4 bolt pulley , you changed that before so you know how to get it off.

I'm guessing when the old pulley gave up its mis-balance knackered up the crankshaft seal.

Parts ordered, job for next weekend if they arrive in time. :thumbsup:
