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...

usually theres a lump on the underside of the piston on the gudgeon pin boss this points to the flywheel

I read it on FACEBOOK so it must be true

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
