piston orientation
hi,
I am about to install new pistons in my 2ltr engine but am unsure of orientation. The pistons I have are not flat top but they have like wedge cut
into then on one half, does this point up or down.
Thanks in advance...

Try lining up the valve pockets in the piston with the valves! dave

^^^^^^^^^^^^^^
I tried that last night and the orientation looks to be wedge faces up. I emailed AA pistons last night so hope to have a definite answer today.
cheers

Yea, I'd say teh cut out at the top of the engine but also interested in the pink dot on one of the pin bosses.
