Vitara piston slap??
hey im having some kinda knocking issue with my turbo d16z6..motor is fully built with vitara pistons and FJD custom length I beam rods, also ACL race bearings and a goautoworks turbo kit. has about 500 miles on motor and makes sort of a knock noise when u let off the throttle,I hear its called a piston slap and is most common with the vitara set up,is this true should i not be concerned?I did compression test and its about 150-160 each cylinder so thats good.
what u guys think? thanks!

I disagree.. From what I have seen it depends on the direction you point your arrows and pwc. We have built several that clack, several that are quite as a mouse.

Op: Which direction did ou point your arrows, I hope you put the big valves in the big reliefs and disregard the arrows, esp with the equal length rods.
Your saying when you let off the gas you hear a knock? Any piston slap I have seen has been on cold starts.
