The two camshaft timing chain kits are identical except the Z22YH exhaust camshaft sprocket has a camshaft sensor (as you say) where as the Z22SE camshaft sprockets are the same and it does not have a camshaft sensor as such but the signal is mimicked by the DIS coil pack module.
It would appear that they have sent you the wrong timing chain kit (part # of the kit you should have received for a Z22YH is 55569838). Did you order genuine GM kits ?
The spacer in the balance chain kit is not required in the SE & YH engines, but is used in the Saab B207 engines.
It is recommended that the crankshaft oil seal ring is renewed as they have a tendency to leak once disturbed and Vx also recommend that the crankshaft pulley bolt is renewed as it is a 'stretch' bolt.
If the chain had slipped by 6 teeth it sounds likely that this would have bent some valves and cracked the valve guides. Also if the chain guides have fragmented, a lot of this would end up in the sump. Presume all of this has been checked.
Thanks for replying, Kevin.
I have gone for an aftermarket chain set as I was originally going to buy Vaux genuine through the Z22SE shop, but these have been withdrawn due to Vaux hiking the prices. I did order against the OEM code, but it looks lime I have been supplied the wrong kit. I am still waiting to hear back from my supplier.
The failure was first a lack of power. When my local mech was trying to diagnose the problem the car was not being driven, and only turned on the starter motor. As soon as it became apparent there was no resistance they stopped. A compression test showed all cylinders at around 30%, so I am hopeful that the valves have survived.
I am now working on this 'project' to verify the valve condition before lifting the head. The biggest headache at the moment is the damper pulley fouling the timing case. It almost seems that either the sprockets are tbinner than the originals, an need shims to build up the space. The damper slides right up to the timing sprocket. Alternatively I may not be getting the timing case back on fully. Doing this job without taking the engine out is a nightmare, but I have no alternative.
If the engine gets running again I will see if any oil seals or gaskets need replacement. I have looked for the Vauxhall tool to fit the oil seal, but cannot find it. Is it required, ir us there another way of fitting the new seal?
