I recently had a t-belt job done, I have driven the car for 600 miles, it sat for about 5 months before this. I drove it intermitently. It held great oil pressure according to the factory gauge, which I know isn't all that accurate. It held better psi than any other dsm I've ever seen.
Anyways, I noticed a slight to moderate vibration from 800 rpms to about 35000 +. I don't recall it having this vibration before. I drove it today and out of nowhere the oil pressure gauge quit working. I noticed that a connector (I think to the pressure switch is rusted off, the wire is just dangling there, but I noticed this a few days ago and it still held good pressure.
I have a 02 dump exiting next to the oil filter, boost controller set to 12 psi, hacked maf, boost gauge. Its all stock, cat and all. Do you think its possible the mechanic misaligned the oil pump and/or bs which destroyed the oil pump? I'm not sure its the oil pump or the wire dangling down....I doubt its that though because of it still holding pressure after I discovered it had broken off.

The car runs fine, but I have parked it for now. Any suggestions....
 
Make sure it's the gauge not the pump. Take off the spark plug wires at plugs or coil., Remove the oil cap and crank the engine ,look at the cams you should have fresh oil on the cam shaft if you don't you have oil pump problems DON'T run the engine until this is fixed. If you do have oil on the cams then it's a wire or sender. As for the vibration it could be the oil pump is not properly timed when you had the timing belt replaced ( hope you replaced all the belts just not the timing belt).
 
The vibration certainly sounds like the mechanic failed to correctly time the balance shafts. To determine if your oil gauge wire simply rusted off, have someone watch the gauge while the car is running and touch the dangling wire to the oil pressure sending unit. I've also had this scare before and you first think the worst.

x2 u might have to wait for a few seconds after contecting the wire for the gauge because it reacted slow when i had this problem

I tried that, there is fresh oil circulating around in the head......i did replace all belts, a blue gates kevlar bs belt. So i think it is sender wire related...
 
so whats the results?

Don't know yet for sure, the weather and my schedule hasn't allowed me to go any further. I'll post when I find out. I don't think its oil pump related becasue of the fresh oil in the head......but if the silent shaft was out of phase...I could see it destroying the oil pump. I hope to get at it this week.

resolved, 2 connectors came unplugged.
