Ferrari Mailing List: Re: Cam timing

[David Thursby (david]

3 hours seems a bit steep. The few I've spoken to about this say it 
takes them less than 30 minutes to do both banks. This is assuming that 
the covers are off to check/adjust the clearances, which they should be 
for all V8s other than 355/360 (and 430 too I suppose...)

With as little as 4 degrees having a significant impact on performance, 
I don't really understand how eyeballing a set of marks so close to the 
axis of rotation can be accurate enough. On a 308/328 done in-car, the 
front bank would be very difficult to get a good line of sight to do it 
even half accurately.

I better be careful what I say, as this could reignite the whole 
belt-swap vs "proper" service argument. I don't want to go and do that 
now do I.... Let's just say that since I do the servicing on my car ( 
Mondial t) myself, I don't have to worry about labor $. I choose to do 
the job "properly".
