Only new parts not mentioned in first post is new clevite 77 rod bearings, new piston and rings for number 3,
New cooling system and gaskets.
How are you supposed to do a crank relearn? Never done one before,
But seen the option in hp vcm scanner.
Happens open loop, closed loop, as rich as 11 to 1, and lean as 16 to 1, and stoch.
Seems to be noticable as soon as idle comes down when warming up from a cold start.
It does have a 180 thermostat with an eighth in hole drilled in it. Temps run pretty consistent at
178, until pulling trailer up a grade. Miss was still there before the new t stat though, just thought it was dizzy wear.
I did not check for slop at the chain. Wish I would have while the plenum was off.
Valves appeared good when the head was off. Not hammered up like the piston and combustion chamber.
Also took the lifters apart and cleaned them up, they were gunked pretty bad, but cleaned up well, and all rollers looked to be in good shape.
Might have a picture somewhere of the head while it was off.
Only thing that went to the machine shop in this half ashed overhaul was
The number 3 piston and rod. Pressed rod on and wieght matched new to old.
I think he said he got it within a half of a gram.
If I was to try and experiment with injection timing, what would you recommend
Targeting for EOIT? Stock it looks about 300 deg, wich is about 30 deg sooner than a stock ls.
Everything I found about it seems to be for an over scavenging camshaft that
Throws raw fuel out the exhaust. Would I want to target a little later closer to overlap,
Or bake one the closed valve longer?
I have put about 15k miles on the truck since, it now has about 155k on the clock
Thanks
