I am kind of thinking overhaul. In frame about $500.00 in parts if the crank shaft is ok. I have the tools and the time. I know that DMiller is right about the blowby.
- With the angle grinder, I cut all the nuts on the studs. I then removed the exhaust manifold from the cylinder head without unscrewing the studs. In this way the threads has no longer load and should unscrew easily .
- On stumps of studs I welded the nuts, so to heat the studs to take it to the red (be careful not to melt them!!) .
- After about 30 seconds, while the tool was acting on the welded nut, I sprayed a little wd40 on the threads of the studs.
One did not want to come loose and it broke the weld flush with the head, I tried again , but first I soldered a washer because it is thinner than the nut and the welding is better, I welded a nut on the latter and this is unscrewed.
- Magically have unscrewed all, and I have not had to make any hole!
