rear crankshaft oil seal

Post by BAZK »

Hi All, I'm in the process of changing the rear crank oil seal, replaced the seal last week & oil still pours out. I think I did something wrong! So I'm doing it again!! It looks like I may not have had the new seal in dead square. My question is, once I've replaced the seal, & put flywheel & clutch back on, am I ok to run the engine without fitting gearbox back on? The reason is obvious!! I don't want to do it all again!!
I 've had 2 240's in the past so have a little idea, I bought this one a year ago,it had been neglected & needed some sorting, The car was leaking oil when I bought it.I have done the flame trap amongst other things.
Thanks for any advice

I'm facing a similar issue with the front seals. Have you checked to be sure you do not have excess crankcase pressure causing the seal to blow out?

Hello, Yes,I did the flame trap last year, & checked the pressure, using the proverbeal plastic bag trick!.I bought this particular 240, with a veiw to restore & am making my way through things, sadly the car was neglected by the PO. Rear seal is now sorted, The first one I bought, I think wasn't very good, I ordered a volvo OEM seal & it was totally different to the first one, , all done & not a drip anywhere!!
