Olds Bravada 1996 185,000 miles
My head gasket went in the truck and I got someone to replace the head gasket. He had the heads milled and has it back together. Now he tells me that my oil pressure is going up and down? What would cause this. I had no problem with oil pressure before the head gaskets.
Any thoughts would be great. I have been without my truck for 6 weeks now and I really need it back. 100+ degrees outside and no air in the car. Help please.
