From what i can see with the records MB did most of the work. There is a gap from 55 to 90 k miles .Maybe it was done then. The head looks really clean.today i verified no compression in two of three cylinders. Time to tear off the head and see whats up. Lucky it happened at low rpm. Thanks for the replys. I also could not find any other treads like this one
Lucky for me the intake valves are cheap
Thank you
Rich
