Re: Engine knocks after starting, thoughts?
Piston slap?
My #6 cylider is slightyly oval at the bottom..... out fo spec, but the wall still has all the cross hatch visible.
The piston skirt slap can be heard for a few minutes - then it quiets down totally.
I did not think this would justify reboring and piston replacement - everything else was still within new engine spec.
Just a thought.
/T
PS Maybe a leak / crack in the exhaust?
