Ailing engine (Updated after teardown)
There is something else that I failed to mention for some reason. I think it is important in this discussion. When I was loosening the head bolts on both sides I could not believe how easy it was to turn some of them. I am used to really having to reef on the strongbar to loosen head bolts. Some of these I could loosen with one finger on the strongbar. Less than an 1/8 of a turn and they were loose enough to turn by fingers only. There were others that required some real effort to loosen. Most of the looser ones were the bottom bolts, (the short ones). These are ARP bolts.
