Can someone help me identify what is going on with my rebuilt engine!?
2005 Mustang 4.6 3v
Brand New JE forged pistons
Brand New Mahle valve seals
Brand new Ferrea valves
Brand new Autolite HTO spakplugs
Recently did a cam phaser job on the drivers side head and wanted to check the bores since the coil packs were off just to see how things looked after the first startup. Engine idled rough maybe a total of 3 minutes here and there as I tried to diagnose the problem until I figured the tone ring or reluctor wheel was out of phase on my old phaser.
These are my questions... (1) Is the piston top too beat up for such short run time?
(2) What would cause severe pitting like this on a brand new piston with a total of 3 minutes run life?
(3) Why are my brand new spark plugs showing burn on just half the plug?
^^^This is cylinder 5. Car has high pressure oil pump (Melling 10340) btw.
