I installed my new AA piston in my type 2 bus engine yesterday and was wondering if it matters how the pistons are oriented in the cylinders? I guess I have a 50/50 shot of getting it right! Any thoughts? Thanks

I don't quite understand. I have 3 different types of 2.0 pistons. The deep dish bus, the shallow dish North American, and the no dish European piston. None have valve clearance reliefs. My pistons also have arrows that point to the flywheel.
If my flat top pistons do not require valve pockets, then that would suggest those pistons do not have valve pockets either, just a relief to lower compression. This does not mean that you do not have them upside down. |
