Oil leaking

I have a 89 Mazda b2200 and there is oil leaking from behind the crank pulley. Is there a seal that can be replaced with out pulling the motor. Thanks in advance.

Yes, but the transmission needs to come out, and the clutch and flywheel come off. When reinstalling the flywheel, use blue threadlocker on the crank bolts.

I think SinCity thinks your leak is at the rear of the engine, but you said behind the crank pulley. Yes, there is a crankshaft seal and a camshaft seal up front (same part number, too) that can be installed with just a little more work than doing a timing belt install.

Is that seal located on the oil pump?

Yeah, I flubbed that one. Sorry.
I need to stop replying from my phone. I can't see the damned words all the time.
