Most topics are extremely vague when I research this so I will start from the beginning. When I got this car the headgasket was blown, I've machined the head and did a 3 angle valve job on the old exhaust valves, and bought new intake valves. I also bought new headbolts and everything is back together and working good. I've also replaced the power steering as it was going out. Now the engines runs fine (along with a small lifter tick) and the low oil pressure light comes on at idle when the car is totally warmed up. And the car completely stalls out when i make sharp turns from idle (so I gotta give it alot of gas while turning, this is an auto btw) because I was guessing the oil pressure switch was reading 0% pressure and cut the fuel pump off. So I replaced the oil pressure switch, same problem. So then I was guessing the oil might be getting all the sludge out from the antifreeze being in the block when it was a blown headgasket, so I changed the oil and it was a nasty murkey black with stuff in it along with alot of metal shavings, I plan to change the oil again soon with possibly 20w50 castrol or mobil1 and see if that stops the problem (which I know is a temporary fix). Also whenever the engine is finally warmed up and the light comes on, the engines runs more hotter then normal (but never in the RED) and my fan kicks on like it should. So I'm thinking it might need new Rod/main/cam bearings but don't want to do it if I hafta reground the crank (thats if it isnt nitrided which I doubt) and probably get a new cam. That or its the oil pump? Which I doubt, I really want to put a gauge on it but I'm starting to just consider a 3400 and forget all of it. Thanks for any insight.
Also I did do an original oil change when I did the head gasket ofcourse.
I have the same problem on my '97 2.2l OHV. Had to do a timing chain and a valve job. I don't have the same stalling problem, though.
At first I was going to recommend looking into the oil pump itself, but if you drained the oil and had a lot of debris in there, you may have a clog somewhere. Have you tried running Seafoam through the crank case?
Thanks for the reply, I do have some motor cleaner to use before an oil change and Thought about using it next oil change soon and see if I can crank some of that stuff out. If its an oil pump this would be easy. But if its seriously a worn motor, I'm v6ing this bitch,.
Well agent omega read my idea run a can of seafoam in the crankcase.I would run it for say 50-100 miles this should clean any left over trash out.I have used it in the past on my cav,and daily mazda pickup does wonders.Good luck
I've heard of this before but it scares the crap out of me putting anything in there but oil. So you guys have done this and it really doesn't do any damage? Also I heard of putting it in with a tank of gas and in the vaccuum lines. Anyone know anything about that?

Ok so I've confirmed its Rod bearings but only because of the problems adding up, so far now the engine was dieing at throttle and made a terrible knocking noise, it was losing power and I was having trouble maintaining speed of even 55 mph on the highway. I pulled over and the exhaust manifold was glowing red so this only confirms the rod bearings are shot. Thanks all for the help! I must make another thread now to figure out my options in the future.
