Yes, I was able drain the gas, and was able to crank over without plugs, then put them back and got the engine started. But there is a noticeable metal on metal sound (more than valve train); the sound follows the RPM.
Compression test was okay, and leak down test was okay at that #8 cylinder and its neighbor. Pulled the intake and the head. The head looks fine visually, but I suppose I could have it tested.
The #8 cylinder has a noticeable lower Top Dead Center and noticeable lower Bottom Dead Center than the others on that side.
I can roll the crank over by hand easily except at one spot: When #8 is at BDC, it gets tough and I need to use a breaker bar to keep turning. Once I get by that, it is easier until I return again to #8 BDC.
I am no expert, but it feels like a bent connecting rod, and it is contacting the block at the bottom.
Dang. Murphy's Law!
