I have an 89 turbo w/ auto @156K miles. I have a problem with oil leaking from under the engine (seals?) and, to a lesser degree, from the oil filler cap. I estimate a leak rate of about a quart per three tankfuls. My car seems to blow out more oil the more I use the turbo. I thought it was a clogged crankcase vent system, so I cleaned it, and, with the oil filler cap removed, blew back through the oil trap, using the existing big hose. It had very little resistance, almost nil. I thought it could be the tyrbo going, so I pulled the turbo inlet hose and tried to wigggle the shaft, but it had no play. But the leak still exists.
Does anyone have an idea what could be causing the leaks, and, once the problem is found, will I need to replace the seals / gaskets?
thanks in advance
Rick
