Alloytec V6 - Potential Timing Chain Problem
Stumbled across this awhile back and thought I'd throw up the link just in case anyone has one, or is thinking about buying one...
Apparently the Alloytec V6 (Particularly the High-Output units) have a ongoing issue with their timing chains, which are difficult to access and replace, which could result in very expensive repairs being required for these motors as they age - doesn't seem to be completely unheard of for them to require replacement by 100k!

chain will stretch by up to around half a link, it then sets of the an DTC for cam signal out of range. They have introduced a revised timing chain which will sort the problem. I only saw this once whilst working for holden, there was a specific VIN range i believe where this problem was occurring. Honestly in commodores not really a terrible job. However if you own a captiva with v6, that is a particularly bad job as its east-west, and you have about an inch of room in which to work.

I had her in something sensible for carting the kids (my grandkids) arounds
a Honda CRV...sensible stuff then one day out of the blue she turns up with this ...SAAB!!!
She goes...oooh aint it luvverly, leather climate sunroof yada yada
and I go have you lost yr mind?
in the 2 years she had it...
I did a timing chain (NOT a nice job)
a heater core - SAAB is the ONLY CAR YOU REMOVE the FIREWALL to fit a heater core
a rear ride leveller...available genuine only & costs MEGA
a radiator...coz the plastic outlet where the top hose goes on...broke off
and a HEAD GASKET (who in their right mind does a head gasket on a Turbo SAAB?)
coz...yes she drove it after the radiator failed
she finally sold it when new tyres were required...yep they are strange too
sumfing like a 195/55 x 16 ...only available in Continental Michelin and Pirellis
and had to be ordered in and some great cost
She sold the SAAB and bought anuvver CRV
and one day I will tell the tale of my other daughter ...whodid something silly too
sold her Mazda thingy I got and bought a BMW (think she is till paying off the loans for the repairs)
