There's rod knock, from what I believe a failed spark plug boot---.
The spark plug boot on 2 cylinders were quite lose, reseated, no improvement. replaced w/ generic (but continuity tested.), no improvement. replaced coil pack, no difference. rod knock.
sometimes it stalls, but it still moves, albeit not fast at all.
and bang bang bang bang bang bang bang.
Is this in your opinion, rod knock? Oil was not low, it showed in the dip stick although black (but changed, a year ago-- less then 2500 miles). Castrol GTX 10W-40.
Personally I would've welcomed head gaskets/overheating.
