Oil pressure help! I've got a braided feed line for my turbo that was unknowingly draped across one of my manifolds. The oil got real hot, hot to the point that the oil pressure went down to ~20. Normally idles 40+ hot. Once it got real low, I shut down and rolled into a gas station to let it cool down. Turned the car back on in about 15 minutes and it was still sitting around 25-35idle but the needle was spiking? like moving around a little bit spiratically. When I drove it home I noticed the oil pressure was getting around 15-20 maybe a little less at idle. It was sitting around 20-25 when I rolled into the throttle just a little bit 1500-3000rpm slowly and the oil pressure was going down slowly as I rolled into the throttle slowly. I let off the throttle and the pressure jumped back up to 30-35 and settled again around 20... I'm thinking the oil getting real hot like it did melted something... say the O-ring on the pump maybe?? I'm hoping it's not a bearing, the motor isn't making any noise at all. It's just the oil pressure thats off. I've already ruled out the sender, changed the oil... I didn't change the filter though, maybe the hot oil melted the inside of the filter?
Sorry for long post.
I posted this in a couple other forums but I figure you guys are smart and I have a turbo!

There are four possiblities:
1. Air being sucked into the oil pump due to a bad o-ring
2. Oil escaping the oiling system prior to reaching the bearings
3. Bearing clearances too large.
4. Oil Bypass in the pump sticking open.

well, it's not moving until this is straightened out...
The oil got crazy hot... I hope it just fried the pump or melted the O-Ring on it.
I don't wanna mess with bearings...

Still, not likely. The oil is not going to pickup that much heat from one oil line (that dosen't pass that much oil) touching the manifold. That small amount to oil flow is not gonna heat up the bulk of the oil that much. At least thats my $.02.
Best of luck.

Same thing I'm thinking. Not enough volume of oil passing through to heat up that much oil. Any smoke at all? Reason I ask is because I know you had your turbo rebuilt. If the guy that rebuilt it didn't do it right, the turbo might not be holding pressure and going strait into the pan. That would be enough oil to drop pressure I would think
