Hello- I've got oil leaks coming from both the front and rear ends of my 54's 235 engine block. From what I've read by searching, It seems there are three places that I can try to fix: 1) Pan gasket, 2) Rear (rope) seal, and 3) Front crank seal. I know there is no oil coming from the top of the engine or the oil filter fittings, so are the 3 items above the only possibilities?
Secondly, when replacing the front seal, is it necessary to remove the front grill and radiator? I'm assuming so since you have to take off the crank pulley?
Finally, I've only seen a few places that sell the front seal. Is this part not commonly replaced? I guess my real question is, how likely is it that the front seal is leaking? Perhaps the real question is, "why is oil getting past the seals?". I'm guessing the rear rope seal is just old and bad. But if the front seal is passing oil as well, does this indicate a pressurized bottom end, perhaps related to a clogged draft tube or similar problem?
I'm hoping to button her all up over the winter so I can avoid those unsightly stains in the summer! Thanks for your help.
