I tried a search on this and nothing seemed to match what is happening to my car. My first question i was wondering what the average 91 turbo goes through oil wise mine seems to be burning about a quart of synth. oil every 1000 miles or so, sometimes within the 8-900 range. Whats weird about it is it will seemingly happen within a couple of days. My oil pressure will be fine for a couple of weeks and then blam low pressure oil and i start to hear a weird clanking sound on acceleration. Fill her up with a quart of oil and she is fine for the next couple of hundred miles and then it returns. It seems to get worse and burn faster the closer i get to my next oil change. Anyone out there have this same problem??
