[V6-12v] Head Gasket Job Imminent

Tue Aug 1 16:07:36 EDT 2006

Yeah,

I already have a new timing belt, water pump, thermostat, etc which I was intending to fit soon. If I'm taking off the intake manifold again, I'm replacing all the gaskets, and the valley pan gasket plus the oil retention valves underneath while I'm in there!

My understanding was that it wasn't neccessary to take the cylinder heads off to do valve train work, but perhaps you know differently? If this is the case I may well renew the valve guides, stem seals, etc...

I suppose I should also renew the exhaust manifold gasket and the injector o-rings, etc?

I think if it's a fairly straightforward 'by the book' strip down and fit new parts job I should be able to handle it - I have the luxury of time as I currently have another car I can use - what's the worst I could do with that particular job if I f**ed any part of it up, and what are the parts of the job, therefore, to watch out for?

I think there are some other things to do “whilst
you’re in there” 
cam belt, idler, water pump & oil check valves I would
say are must do items 

Then you get into things that might be worth doing
(depends on milage) like valve grind, new guides etc

Could turn out quite expensive just for parts

I don’t think it’s particularly hard but it isn’t
going to be quick. 

I think that if NEEDED doing I would do it myself, to
give you an idea I did a clutch on an I5 quattro, it
took almost all weekend and pulling the heads sounds
like the same sort of time to me. 

As the head bolts are single use I might be tempted to
try the ¼ turn again.

Best of luck with whatever you decide
