Engine Mechanical problem
1996 Toyota Corolla 4 cyl Two Wheel Drive Manual 175000 miles
My engine was totally rebuilt last month and I have taken it back three times because it blows blue smoke for a second or two on startup. The last time the replaced the valve guides and seals. Again. No change. They cant find the problem. The hitch is that it ONLY does it if it is pointed uphill when it is parked. It doesnt do it on flat ground or when pointed downhill. We are all stumped. My next plan is to pull the PCV out just before I shut it off and see if crud is running down into the injection horn when it is on that angle, which would indicate that the valve stuck open. If thats not it, I am totally stumped. Any other stuff I could check?
