Cracked manifold ????

[coco]

Can anyone tell me if the exh manifolds on the Coupe 20v's are prone for cracking ???

My one has a slight leak when cold but goes away when its warmed up and just wondered if these are prone for cracking as thought if it was the front pipe gasket or manifold gaskets at fault it would make the noise all the time would it not ???


Also are the 5 branch manifolds worth fitting as seen a few advertised, do they give much of a performance gain at all ???


Cheers.

The cast manifolds can crack, BTDT.

Are they a pain to remove ???

it can be yes. the nuts underneath can round off and access is pretty ****,if you decide you are going to fit another cast one you can have one of mine for free.Must have 6+ kicking around.

IME 2 of the EM bolts will snap, so you'll have to remove them too. Quite a tricky job with the head in situ.

If you do have to remove studs then be careful not to snap off a torx bit in the head

4WD's right though, 2 will snap (no more, no less)

Cheers for the replys guys, sounds like its going to be a fun job then eh !!!


Anyone got a 5 branch manifold going spare then !!!!! Might try and replace the standard one if im having to go to the hassle of removing it, might free up a few extra ponies and all !!!

if you get a 5 branch make sure you get the next section of the exhaust with it and the heat shield is a good idea

Will they join up to the rest of the system without too much bother then ???

[spink]

make sure you get that section as i doubt it will be cheap to buy new.Seen the whole lot selling on ebay for between £50 and £80 in the past
