Hello guys!
Last summer I made engine rebuild with CP pistons (clearance0.0035") and everything was good.
But in the winter when it is cold 0C and below, at morning cold start there is a sound like pistons clap,
when oil gets warm to 50C, the sound disappears.
The sound isn't so similar to pistons clap, as to an example at Evo9.
What in your opinion can make such sound? Pistons, vanos, chain?
