Excessive oil burning
« on: August 10, 2006, 08:53:43 PM »
This problem isn't on my Jeep, but my '89 Probe (still a 4 banger  :lol: ).  Here's the story from the begining:  The seal on my oil pan was weak, and one day when I downshifted, she broke lose, and on my way home I ended up strippin out a few rod bearings and the single item that costs more than the whole frickin car, my turbo :( .  I ended up buyin a used engine for nearly 700 bucks that was "complete" without the exhaust manifold and turbo.  For a "quality used" part, it sure was a POS.  I found a WASHER on top of a piston.  But anyways, I rebuilt that, but used the head from the engine I replaced since that was new, and I still have a problem with burnin oil.  Recently I just came to the conclustion that I might have stripped out the valve guides and they are leakin oil into the cylinders.  Whenever I start it up, and let it idle, it's perfectly fine, not smokin at all, but when I give it some gas for a few seconds, then the smoke show starts, and if i stay on the gas long enough and let off, she'll bog down and stall.

So what do y'all think, am I right about my valve guides, or could it be somethin else (I did replace the turbo, so it can't be that).

Thanks.

Could be rings, are all the plugs showing the same color, maybe just a single cylinder is burning oil. Valve guides usually leak more when at idle but the only way to really know is to inspect your guide seals and if they are good it may be rings. Could also be sucking oil in by the head gasket or air intake which is easy to check.
