help!!!! I have a 1995 Z28 camaro, I was driving like an idiot at high speeds and overheated the car to the point where it shut off. I let it sit a few hours and came back to pick it up, car started up a lil hard then ran ok except for the fact that the oil pressure was low and check gauges light came on. As i drove the pressure rose slightly to maybe 20 or so but as soon as i get to idle it dropped like a rock. I went home left her sit for a month an have now done an oil change on it with 4 quarts 10w 40 and the rest is lucas oil. At start up oil pressure is ok but not like it used to be and after running the car a bit the pressure drops like a rock at idle again any thoughts?

 

You ruined your engine. The engine didn't "shut off", it got so danm hot to the point where it "seized" (heat welded parts together). You most likely did internal damage to the cylinder walls, piston rings, and gauging by your low oil pressure, your bearings too. The temperature gauge, with the red danger zone markings, is there in the dash for a reason.

 

Sweet Jesus, how long did it take for the car to seize?

 

Story time...I had a 96 Roadmaster wagon, LT1 motor. I drove it for about 2 hours with the temp in or JUST below the red. It's a long story why, but I did. It seized on me, no clanking or anything just valve clatter, then nothing.
I tore it apart and had a cracked head. It cracked near one of the exhaust ports. I think this was the issue that caused the coolant loss causing the overheat.
I checked the cylinders for scoring and they were acceptable. I could still see some cross hatching after 130K miles. I checked the lifters and they were ok, no scoring on the rollers, I just rebuilt the top end.
I put 2 new/rebuilt heads on it and a new opti and drove it for 2 more years. I had 1 piston that would slap at cold start but quieted down after about 2 minutes. I didn't drop the pan to check the bearings.
I may have gotten lucky.
It didn't have an oil pressure gauge, just an idiot light.
Suggestion: You might try a heavier weight oil to get the oil pressure up until you get rid of it or rebuild it.

 

camaro 69 is correct because you allowed the car to run at such a high temp for so long you killed your engine basically what happened was that your engine became so hot that the parts inside of it warped due the temperature so ya looks like you need a rebuild or new engine

 

Like everybody and it only takes one bearing to get hurt to show signs of weak oil pressure and/or some piston slap.

How low is at idle 6 20 40 < btw those are acceptable according to GM
