This has got me stumped. Got low compression on right bank 1 and 3. I have checked the timing belts and everything lines up as it should. Just took it apart again and all marks line up. Did left side and rotated 360 and line up right side to marks. It sounds like it's leaking on exust valves was wondering about moving can one tooth advance on valve gear. I collapsed the lifters and they pumped up after it ran a while so they should not be pushing valve down to far.

As i said I'm stumped help and ideas might help.

PS

This is on and EA82 carb motor:mad:

Please verify that when the middle of the 3 marks on the flywheel is aligned with the pointer, one of the cam gear pointers is at 12 o'clock and the other is at 6 o'clock.

ok when rotated 360 the left side cam gear is points down at 6 oclock and then I line up the right side. Using the three marks on the flywheel for both sides. just as the book says.
