I have been fiddling with my 2.2l 16v with broken clutch. But there was a LOT of other issues. Namely a missfire or hesitation upon throttle. What i have done so far. Replaced clutch (problem solved. Also removed and welded up the cat (holes) ,Cleaning out the rocker cover+gaskets, crankcase breather pipe (totally plugged) cleaned out the carburettor, The hole was plugged to idle controll. Still have the hesitation. Also waterpump, and plugs were renewed, The same problem is still there, but it started to run better today and ran hotter. There was a hole in the purge hose. But noone of my many measures has been able to cure the problem entirely. Before removing the old timing belt, i checked the timing. It was slighty off. I did change everything. Tensioner and idler pulleys. But i have the small timing error again. It is not possible to have it lined up 100% spot on.... Now a thought that no one has discussed (or i have not found a discussion about this) The godamned waterpump can be rotated. On all other cars i have worked on this is fixed and one cannot mount it incorrectly...But on the omega 2,2 16v and probably all 16v engines it can be rotated.. and that would affect the length from crankshaft pulley to the camshaftpulleys. I did mark the wp before replacing and fitted it the same way i got the car. But since i cannot align timing perfectly, would that not be the probable error??? But no one has ever mentioned this. The wp:s moutning will affect timing!!! so if i now loosen the belt again and move it one notch, and loosen the wp rotating it clockwise, i should be able to correct the small error ? The are no error codes now. But there were a few i read with "My Naff Code Reader" and software. It was the camshaft sensor and a lot of other stuff, probably related to prevois owner forgetting to fit all the connectors. But the real issue should be the timing being slitghly off, possible involving the wp not being in the place it should ?. Next question, How sensitive it the timing error? If the top cambelt pulleys are spot on the crancshaft notch is 5mm Counter clockwise from the pointer. But for each thing i did the issues became less and less a problem. Maybe a few hours of burning out shit from all the holes and plugged holes, will have it back on treack. I have replaced all one can replace it fees like. I just want someinput on the slight timing error, from a knowlegeadble person. It cannot be solved only with the tensioner. (worn and new setting).
