Hello,
I've recently bought a mk4 Astra Bertone with a Z22SE engine. It was very cheap and I knew it needed a lot of love. With the car I got a spare engine block (used to be in the car, due to bad maintenance was seized).
We tore down both engines and they have different pistons and rods. The rods only look different, but they are the same length, size and all that. But the pistons are noticeably different.
One engine had pistons with slight grooves for the valves, while the other engine...
Z22SE piston hight difference
