132009, randomly losing oil pressure when driving
Posted by rshissler, Oct-22-10 08:56 AM
No i got an even bigger problem with my POS Talon. I finally got the thing back on the road and inspeted. Was driving to work yesterday, Got on it just becuase i could. Ran the car throw first, 2nd, then 3rd before i left off. Looked down at my oil pressure gauge and it said 10-0psi. I pushed the clutch in to shut the car off and the gauge needle jumped to 40 psi. so i thought alright thats weird. Now i've noticed just randomly driving, usally under 3k, the car will lose all oil pressure, untill i either rev the car up or it'll go up by itself. I'm lost on this one. I've searhed and one thread said bad rod bearings could cause a lost in pressure becuase of the clearences. I know the rod bearings weren't pretty when i was in there before (i posted pictures of them before) but i figured they'd hold up for awhile yet. Another one said that the srping in the oil pump might be getting stuck and there was a bolt that could beremoved to check that under the car. Anyone know where that bolt is? What are the chances my oil pump is going out? i know stockers rarly go out, mine only has 80k on it.

I'll ask the obvious; are you sure you're not low on oil? Perfect description of that.

Then the next idea would be check to be sure the wire is good at connection etc.

Of course, you ARE still back at those rod bearings. BUT that would normally show at idle, not random or high rpm.

Also, (I think I know the answer but I'l ask anyway) OEM oil pump?

OEM oil pump, Mechinical Oil Pressure gauge, Just changed the oil with 10w-30 synthetic.

alright today i jsut went ahead and changed the bearings with new ones, plastigaged them, everythings with in spec, new 10w-30 oil and new filter. Everything was great left the car warm up to normal temp, car ran quiter and smoother (might be in my head), and oil pressure was higher. Took it for a 5 min drive and the gauge did the same thing, but only once. Im guessin the gauge is messed up inside.
