I heard Arias pistons are common for having piston slap.... anyone have this issue with their Arias, and if so how loud is it at idle and throughout what RPM range and does it go away ???

I did a search and could not find any info...

Thanks in advance...

arias pistons tend to run looser clearances which makes for a lot of noise on cold
start. generally it gets better when it warms up, but it sounds like a diesel until
then.

You know it's that way with my JE pistons as well. Hopefully my Weisco's will be quiter.

Also I think that the silicone content in the Arias pistons also has something to do with the slapping b/c of thermal expansion characterisitics of silicone. Once they warm up they arent that bad. I kinda sounds like your lifters need adjustment if that helps..
