The change was probably due to the fact that there was a problem with cracked gaskets under the head. Btw Seat have only CUNA engine, no CUPA, but rathe the same engine. What was your oil consumption ?

hello, I also have a modified engine for 100k km and the oil consumption is almost the same. I have 1l at 5-6k km. Now I was talking to a friend and he solved this problem by exchanging the pistons, which have a third ring higher. The original is 2mm and he put a piston with a 3mm third ring. He is now driving 5 km from the repair and it didn't take a drop of oil. The bonus is better engine sound and even higher performance.
