Title: changing exhaust manifold gasket on a 2.0
Post by: dippydave on 09 July 2009, 10:56:36

I need to do this, and can't find any helpful how-to's or maintenance guides.

Anyone any pointers?

Like how to change the studs too, which appears to be a good idea?  :-/

It is only a 2.0 16v so lots more room than the v6  :y

Check for broken studs before you start (feel and mirror). You must soak the studs and nuts in PlusGas for a day before you attemp to undo them. If you have any RustFlash (freezer spray with penetrant) this is very good.
You are likely to find a broken stud at the front and /or a cracked manifold so be prepared.
Before refitting the manifold check it for flatness and flatten it with a file and emery if needed.
Have a few studs and a new set of nuts ready...there can be a lot of errosion because of the heat.

QuickFit changed the manifold gasket on a 2.0 I had previously, they broke a stud and re-attached it with body filler.......it didnt work >:(

that sounds like a plan - although how far of a run? it takes a fair while to cool I think!

bad news is I took the heat shield off today (only held on with two bolts but hey) and I think I found part of the manifold missing at the downpipe joint. oh and the nuts look well tired :( bit like me  8-). anyway gave em a good soak in wd40 while i was at it. Does Plusgas differ from wd40 anyone?

I have already bought gaskets, studs, nuts etc but realise this isn't a quick job (nor should it be) and an experienced hand would be better than my novice one!

TTfn nighty night

I'm in Dudley so not far :y WD40 and PlusGas are very different, do a search on here as that argument has been covered several times ;D Have a look round the breakers yards (I suggest the Saltley lot for you) for another manifold but check it closely ;)

Thanks again for all the advice and offers of help, but as I ran out of time and had several other problems with the engine, I ended up paying for this job to be done.

Manifold needed skimming as it had warped slightly, but all the studs came off no trouble  :y Don't know if they used plusgas or not, but I'll be investing for my next trip down stiffnutalley!  8-)
