[QUOTE="JAJ, post: 16076313, member: 131874"] I agree completely - there's just no pattern to the symptoms. Either of the two problems, if there are really two problems, could have many different causes. The one thing that seems to be repeatable is the "un-repeatability" of the failures - sometimes the "loss of oil pressure" issue happens on the way to the next braking zone and sometimes on the way to the mall. The problem seems to come at the premature end-of-life of a component (ie - a manufacturing defect) rather than because of something that's wearing out or being over-stressed. Same with the oil consumption - it just seems to switch from low to high consumption at some point and from then on the engine's on its way to replacement - there's no recovery. My pet theory on the high oil consumption is that it's a valve-guide seal issue, not a piston ring problem. Although I suppose if it was that simple there'd have been a running change by now and it would have stopped on newer engines. [/QUOTE]
