Thank you all for your input.
My 2006 SVZ has 140k on the clock, It's my only car (used to get to work) and i am getting the timing chain done next week at RevHigh Hallam.
i have the error code P0016 - indicating camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor.
The car is driving fine as well, not even rough or anything (it's the only car i have so i have to drive it to work 10kms) I get the Check Powertrain light coming on.
I have 4 more days of driving it before i get the car in the shop. ( The car is not in limp mode or anything, i am just driving cautiously)
I contacted RevHigh, and paid $100 for a booking. They seemed to say timing chain replacement, but I'm wondering how they could just say that straight off the bat without any diagnostic? Isn't there a swap sensor thing you can do to see if senor or chain is the culprit?
Will they do a diagnostic or something? or am i just going to get staight up slugged for around $1500 timing kit and, oil pump + oil i think.
I see they are a sponsor of just commodores too, i hope they see this.
