my car was running really rich due to bad o2's and what i think is a slight exhaust leak
but any way my oil pressure was low causing me to go insane thinking spun bearing
but i found out it was just gas in the oil from runing to rich
but what can gas in the oil do to an engine?


and im changin out the pacesetter exhaust gaskets for some felpros to see if thats where my tick of death is coming from

 

It will ruin your rings,bearings,seals.In other words,mess it all up. Get the O2's fixed and change the oil a few times to flush it out.

 

well i found some nice little sparkly bits in the oil so yall think its trashed or maybe theres a chance it will live once again?
well i guess its time to start savin up to rebuild any suggestions for low budget and 400ish hp lol
but seriously ya think if i flush it out a couple times it might be alright

 

Don't think the O's caused the rich condition. I think the O2's were the victim of the rich condition caused by something else. More likely a hole in the FPR diaphragm, a leaky injector or a dead cylinder. I don't feel (someone may disagree) that the O2s will cause the engine to be so rich as to dilute the crankcase. The first clue would be hard starting when the engine floods. Did you notice that? If so, more than likely it would have started easier if you held the throttle to WOT when starting.

My first guess would be a dead cylinder. I would check that first. The next thing to check would be the vac line on the FPR to see if its wet. Last, check for a leaky fuel injector.

If it's the result of a dead cylinder, the first thing to do is find out why. Probably spark but if not, then from valves. After that you need to check the cylinder for leak down as "souping" can scratch the rings and piston wall.

If the problem is fixed, you have no reason not to change the oil and filter and give it a try. What have you got to lose at this point.
