Not much help but I wouldn't have changed the chain type in the first place. On my early engine the primary Morse chain had stretched and the Secondary roller chains were fine. If I were you I'd put it all back to early type and sell the later parts you've already bought.
Thanks for your comments. The main problem now is that we're trying to verify (just to be 100% sure) has anything else apart from the chains, guides, tensioners, sprockets and VVT's changed along with introducing the second design timing kit. At this point my friend from the garage isn't positive if the timing kit for Cadillac / Pontiac / Saab / Suzuki 3.6L engines is exactly the same as for the 3.2 JTS.
Is someone able to confirm are these 100% the same setup?
Did the first design 3.2 JTS have the same specifics as for the 3.6L GM engines (as below):
First design timing kit
: 78 link
primary silent chain + 2x 92 link
secondary roller chains
Second design timing kit
: 96 link
primary silent chain + 2x 114 link
secondary silent chains
Are these two sets exactly the same for the 3.6L GM engines as for the 3.2 JTS GM engine?
After replacing the full timing kit from first design to second design on my 159, the mechanic suggested that perhaps there where some differences between the 3.6L GM and 3.2 JTS timing kits - although from my understanding these are exactly the same and users on AlfaOwner have successfully replaced their timing chain kits using the 3.6L sets imported from USA - is this correct? I purchased the recommended Cloyes kit number 9-0753S along with original GM VVT's (these couldn't be wrong, as only the newer type of VVT's can house the second design silent type chains).
The person performing the timing kit replacement claims he's having trouble to align the VVT's on mark, as after changing from first design to second design I believe it's the exhaust VVT's that have their marks up-side-down now and the engine currently won't start (it does misfire every other cycle). If the timing chain kit's on both the 3.6L GM engine and 3.2 JTS are in fact the same (I'm nearly positive they are) this may be a problem of getting the marks set / alignment done correctly on the new type of kit.
Is there anything I can do to help you help me - like photos of the current positioning, close-ups on any specific elements to verify is the marks / symbols are properly set and aligned?
Have you changed the solenoids? My 2.2 JTS was running very rough until I bought and fitted new solenoids that control the VVT.
Thanks buddy, now it's an issue with misfiring and not running at all - therefore this is definitely related to the timing kit itself and my friend is positive that the solenoids for nothing to do with this specific symptom. Cheers for sending an idea though
