since we're on the topic of oil leaks how about this one. On my '83 turbo, i keep noticing this little oil drip from the corner of the crossmember.. turns out to be the oil drain tube from the turbo. I've had this stupid tube off and back on twice now. i've replaced both the rubber o ring and the the upper gasket each time with brand new....its still leaking from the gasket where it bolts onto the underside of the turbo. it only seems to leak when i really get on it, but its enough to make some smoke burning off the exhaust downpipe and drip down the crossmember... any ideas for sealing this up better?? i have one spare gasket left...hmff..
