Top End Rebuild

Well I got the news yesterday that I'm going to require a topend rebuild - Cams and Followers - on my GTV. Cams are an eye watering 320 each Followers 14, and I'm led to believe installation is fairly painless in that the belts don't have to come off in order to carry it out.

So any info on other things to look at, horror stories and what have you feel free to add to this thread...I have a year to do it in having got my freshly minted MOT yesterday.

Re: Top End Rebuild

Bad news my friend... Can I ask why you need the top end rebuilt? Did a belt snap?

Good luck!

Re: Top End Rebuild

If they arent new I'd change the belts while I was in there!

Re: Top End Rebuild

Why will this improve your emissions? Were the old cam followers or even the cam surfaces very worn? Or was an aftermarket cam fitted which altered the profiles?

Re: Top End Rebuild

Would it be cheaper to find a scrappy with some descent second hand heads??

Re: Top End Rebuild

How can you change the cams without taking the belt off???? Aren't the cam pulleys attached to the end of the cams? Get the variator done while your in there if it's sus.

Re: Top End Rebuild

I would be surprised if changing cams and followers would change the emissions of the car but I guess it depends on which emissions are closest to causing the car to fail the mot. My turbo has been on the absolute co2 limit for the last four years so maybe it is just a common feature?
I have tried to reduce this level by changing the AFM and Lamda probe but on both occasions the CO2 level is exactly the same. I have both parts available as spare, if you are interested PM me.

Finally, if you do decide on top end rebuild, surely you can get away adjusting the exhaust side and just replacing the followers on the inlet(maybe other way round) rather than replacing the cams? And I agree, from the manual, it doesnt look like you need to remove the timing belt! although how, I am still bemused by.
