Thats what I was thinking,but my ? would be about the lifters,are they
solid or hydralic,if they are hydraulic,are they good?
I dont know everything about engines,but I know that if theres a bad lifter,
or a flat lobe on a cam,it could create a problem that some people might think
its in the timing.which could have been the problem all along..
Hydraulic. Yep, was hearing something for awhile, loud click, metal thump. More wrong possibilities. But the lifters are all moving as should when turning crank (since heads and intake manifold off, so far smooth).
When heads were on, even after plugs out, the tightness when turning crank was not consistent, but in sections around the cycle, like something with heads causing a sluggish sticking (felt really tight on some of the strokes).
Also while inspecting heads myself with a light, noticed some small amounts of coolant floating around in some of the intake and exhaust valve chambers. Hope that got in there from from me taking them off and moving them around. But the coolant passage ways do look very corroded, or like oil and coolant mixing? And was some rust in those passage ways.
Going to take them to a machine shop like suggested, but not looking good. But hopefully will not be as bad as I am thinking.
Agree that this was not with timing at all now, just seemed that way from the sound of it. And chain is a little loose on both sides, not just the left, but if ok for a little slack, then I will leave it be.
