best place for forged pistons, standard bore... recomendations?...


Recommended Posts

Yep, piston slap, which is the knocking noise you get as the pistons wobble about in the bores. It's only noticable when cold.

Cast pistons don't expand as much as forged ones, so run tighter in the bores, but I've heard many a standard VR6 piston slap in the mornings. It's perfectly normal.

It's best to just get in drive, no fannying about warming up the interior and de-icing before setting off....that does damage.

Unless they have stock cast piston clearance (unlikely for forged), they WILL slap. Just because you may not hear it, doesn't mean it's not doing it. Some forged pistons have moly coated skirts.

I can't hear piston slap over supecharger noise either ;-)
