omega running problems- help me !!!!!

[rpont]

i took the heads off when i did the engine change, and as you are aware you have to take one cam out of each head to get to the bolts, is there any way that i could have fitted the wrong cams to each head. is this possible?? if it is would this cause what i am experiencing.

It's possible. Have a lok at the pictures of mine before I took the heads off. On pic0003 it shows the camsaft positions for cylinders 2-4-6 with the crankshaft at no1 TDC and compare it with yours.

Have you got the sprockets on the correct pins, no 3 for inlet and no4 for exhaust?

There is some identification on the camshafts but I can't remember what it is. If no one has posted anything I'll have a look at mine tomorrow, they are still out, and see if anything is obvious.

I've just re-read the thread and seen that you only removed one cam from each head so you couldn't have gotten the inlet and exhaust mixed up for 2-4-6. Maybe one of the sprockets  is on the wrong pin?? All I can suggest is have a look at that pic and compare the positions of the lobes.

My cams are stamped at the rear end, away from the sprockets.

Inlet N
Exhaust D

I wasn't sure I had them the right way round so I went out and checked again and I've got 3 N's and 1 D. There is also a number stamped in the middle of the cams and they have 3 F's and 1 E stamped in the middle. Could I have 3 inlet and 1 exhaust cam???

Would it run??

Mine is a 1997 2.5 v6

I saw a post saying inlet was F, exhaust E and for 3l inlet G exhaust A.
