I have done some research and all signs are leading towards head gasket replacement, but wanted to get some advice while I am thinking about it.
The back story...My 47 D24 sat for about 2 years and every once and a while I would try to start her with no luck. I recently replaced the battery and ground wires and was able to get her started, but the intense smoke filled the garage so bad, that I had to stop the car. I check the compression on all cylinders and here are my results:
1 - 0 psi
2 - 90 psi
3 - 75 psi
4 - 75 psi
5 - 65 psi
6 - 70 psi
I pulled the head and the 1 cylinder has a stuck valve, but all others seems to be opening and closing OK.
2 questions...1) how do I unstick the Valve? 2) while the head is off, is there anything else I should look at as far as maintenance?
Thanks!
