Hi,

does anyone have the sheet for the HKS pistons ?? Number: 2103-RN019

Clearance is low as they are I think 4032 not 2618. Nickel coating gives great knock resistance.

if using HKS rings use a wind up ring compressor or you will break the oil rings. They have a lot of tension. Very low blow by, dry catch tank. I tried with a tapered hoop type tool and broke 2 rings. New ring pack not cheap.

Hi,
thank you.
My problem ist the lost of the cross cut after 4000km - but only cylinder 4-6. Cylinderwall 1-3 looks perfektly. Clearance was 0,55 - 0,6 (new block , new HKS pistons )
