Ferrari Mailing List: Re: Changing fuel injectors

[Jeff Greenfield (coyote]

Rui - 

If all your are doing is changing the injectors, no need to remove the
plenum or intake at all. You may need to remove the throttle body housing
however, to get the two middle injectors on the rear bank out. This means
you may need a new gasket for the throttle body.

If you are replacing ALL the coolant hoses, then you will need to remove the
plenum only and will not need to separate the throttle body from the plenum
if you do the injectors at the same time. You may wish to replace the plenum
gaskets while you are there.

One big word of caution ... there is a spacer on each stud under the plenum.
Be very careful when you lift the plenum off to make sure that all the
spacers are held or stay in place. If one of them should fall off, go down
the intake, and a valve were to be open on that cylinder, this would make
for a very bad day indeed.

When you are doing the coolant hoses, there is a steel nipple on the intake
that tends to rust, T. Rutlands sells a replacement in stainless.

HTH, LMK if you have any further questions.

So the general idea is to leave the intake manifold alone ... what about
changing the hoses without removing the intake? Can it be done?
Another thing I forgot is I'll be changing the thermo time switch too.
Anyone done that before without removing the intake?

I just want to make sure I'm having the right approach before I start !

Thanks
