    72 c10 oil problem

    I have an unknown 396 in my truck and was having some noise trouble. I had a small tap that was really getting on my last nerve. I ended up finding out I had 3 collapsed lifters and a bronze looking material (kind of like very very very fine glitter) mixed in the oil that was under the intake. I pulled the magnet after and there was nothing stuck to it so I dont know where this material came from. I ran the engine with the valve covers off very shortly and had very little oil coming through the rockers. After the lifters were put in I torqued the rockers back down and put the motor back together.

    After I primed the motor it started on the first crank. Only problem now is there is no oil at all coming through the top end. My dad seems to think it is a spun cam bearing blocking an oil hole.

    What do you guys think it could be?

    Sounds like bearing material,,,time for a tear down. I would assume your oil pressure is low or at the very least it's fluctuating.
