I have removed the head on my 1952 M-38A1 because of low compression on cylinders 2 & 3. I expected to find a leak between those cylinders in the head gasket but did not find anything there. After removing the head and removing all four intake valves, I find carbon build up on the intake manifold side of the valves. The seating surfaces appear brownish but not pitted of worn noticeably. I did find the o-rings under the caps around the valve stems. I do not understand their purpose. I did not find another seal at the top of the valve guides. I do not find any spec on the "valve guide to valve stem" clearance or any reference to sloppiness of same. What else should I be looking for?
Willys Jeep Parts Tech:
There are no other seals there other than those O-rings. It sounds like the issue may be the piston rings. I would take a look at those given you dont seem to have much wear on the valve. I would also check your cold clearances on your valves.
