i just got done with a cam swap and drove it for a day or two and found that i had a blown head gasket. i took it apart and put it back togather and now there is a really loud knocking coming from the driver side.

the ONLY thing i can think of is i did not shim my pedistal mount rockers, i did it last time, do i need to do it every single time. i just would not get why it would change.

did the coolant and oil mix???

What he said...coolant is nasty on the bearings.

if the oil and coolant mixed and you ran the motor like that you can kiss the bearings goodbye[:@]

yeah if any, and i mean any coolant got into the oil you should have changed the oil before you started the car.

no, no water in the oil and vice versa. i dont know if the lifters are collapsed or if the valves need to be shimmed again. thanks for the input, its just one of those things i can not find a solution. its never done this before, when i figure it out all post it so others wont be like me.
