P.E.,

The head gasket failed at the back of the block. Is the camshaft feed at the back? Would this account for a total loss of pressure?

Thanks a million for the response. I guess I need to pull the oil pump and investigate. I did not think to look at the oil pressure when it occurred. All I could think was to kick in neutral and coast to the side of the road.

From what you're saying it sounds like I did indeed experience a total oil pressure loss.

Have a great day,
