3200 GT cam/timing belt change

thnk very much

And make sure you fit it correctly, not just chuck it on how the old one came off!
As the rear chains will have stretched a little over time you'll need to adjust the vernier's to get the cam timing back to spec.

interesting. While i fully appreciate the need for the valve timing to be spot on for top performance, I would be curious as to how many dealers or decent indies would do vernier valve timing adjustment on every timing belt change? Especially since its not just a wee screw that you can tweak to get the timing right, it requires removal of the chains and quite a process with pins and stuff to get any adjustment of the relative valve timing if I remember correctly, and not a job for the faint hearted in any way. So Alfatwo how often have you actually altered the relative valve timing on your 3200? I am interested!

When Stuart at Shiltech completely rebuilt my engine 1400 miles ago, I watched him do it, It didn't take him long as he's done lots before

You don't need to remove the chains just undo the nuts holding the sprocket's as per the workshop manual,my left hand exhaust cam was found to be miles out

They say they always check on a belt service

That's very interesting. I'll definitely look into that. Am I right in only seeing upsides here? You get better performance and efficiency with no downsides other than certain death the moment you dare turn off the traction control?

Is there a way I could benchmark this using the ECU data? I'd love to do this and run a before/after comparison.

Interesting, any idea how doable it is with the engine in-situ?

I am sure I have seen a picture of Emblem doing the cam chains in situ so it must be do able but can't be easy . Thought I heard you may have to move the engine froward a little to get room on the nearside. Perhaps one of our sponsors can confirm?
