any oily residue in tailpipes?like rrr says, get a leakdown test done, not that expensive and a good tool to have. i had a leaky 340, ended up being the cam thrust plug at back of block
ive popped the '' diaphragm'' on oil sender before backing out of driveway, it went with a bit of a bang! maybe give sender a real close inspection, it may have ruptured on top side of it
ive got a 72 demon , 318, just picked up a 87 d100 225 slant six, I know this isn't the right forum, just looking for help! who makes headers for slant six? abody , truck or otherwise?
