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.
