well pissed off my old mans manifold had cracked on his 4x4 inside where the turbo bolts to it and someone off here pmd me saying he had 1 so i sent the money got it today and guess what a crack in the same place im well pissed about it as i asked if it had any cracks before paying and was told non att all otherwise i wouldnt of brought it so it must be a common thing on 4x4s so next time ya turbos off take a look

Yes, cracks are very common on 4x4 exhaust manifolds......cant recall seeing one without any cracks TBH So just a question of avoiding badly cracked ones

cossiecrew

if i get an uncracked 1 whick i will how do i prevent it from cracking what about a spec r turbo damper they any good ?its got a t34 if that makes any difference to it fitting

but get a damper anyway

cus it will save your head studs snapping

i had 5 studs sanpped in mine when i took it off

cossiecrew

lol his had 1 so whats the best damper around to fit t34 on a 4x4

i ordered a sepc-r one

its a big hchunky block not the 3 pronged one like bailey

this is designed for that but bloody expensive

didnt need it after that cus going different manifold and just sold it about a month ago on ebay

but that would be the best bet

If you are going to get a damper anyway, then why not use a 2WD manifold instead of the 4WD one? The 2WD item is better for big power and there are 2 or 3 dampers designed for it.........

SapphyMike

4wd exhaust manifold means you dont need a damper.. i dont think a damper will fit.

cossiecrew

they wont fit 4x4s why not

xr4x4rs

iTrader: (5)

adamper will fit spec-r do one

4wd manifolds are worse for cracking than 2wd

but a 2wd is better if u want big power etc

cossiecrew

but its not just a case of changing the manifold is it theres other things involved aint there right im goin in search of a spec r 1

cool

easier to ring them

speak to pete
at spec-r

cossiecrew

pete whats your price then

If you change to 2WD fanimold does that mean you have to change your downpipe to a 2WD one?

I've heard the 2WD manifolds are a pain to fit with the engine in, is this just because they are much bigger or because you need some decent shaped tools for the job?.....do they use the same studs as the 4x4?

never seen one without a crack in it , even allegedly mint ones ive looked at have cracks in them when you clean em up

Glenn5

dont the spec-r 1s only fit a 2wd head

richm

like this one?????



been like it for years, very common, and hasn't caused a problem...

cossiecrew

thats the 1 will have to see what tommorows brings

RichardPON

Nope, cos I had one on my 4x4 head.

The idea is you fit a damper when you have the 2wd manifold and 4x4 head combination, as the 4x4 head doesn't have the lug that a 2wd head has to run the std damper.

Why you'd want to run a damper on a 4x4 manifold is beyond me.

richm

yep, won't have any effect on the cracking we are talking about here, that's purely temperature-induced

cossiecrew

yeah ive looked at it and see that its a heat issue what pisses me even more is that the 1 that turned up today was the 1 i payed good money for

ian.gordon

mine is cracked too in the same place

frog

Phewwww, I've been told not so long ago that a t-damper was unnecessary on a 4x4 and started to have second thoughts, that clears things up. Thanks Rich/Nath

Beach

Unlucky mark hope ya get it sorted for sunday mate

whitneyd

Does anyone make a damper for the silver top head?

space hoppers

i have had the same problem the crack just gets bigger iam going 2wd manifold no uncracked 4wd ones i do no GGR has new ones but dont no wot price from ford they are over 600 quid. getting t4 turbo hanger from spec r as my car is the show car as well as t38 turbo which turbo technics changed over for free as turbo was still new exhaust should fit according to MAD

space hoppers

you are spot on there mate

whitneyd

Mine is like that any any other 4x4 manifold I've seen. It isn't crack to the outside and it doesn't cause any problems.

richm

yeah, exactly, the crack in mine is just on the internal casting web, no sign of it at the outside.

Azrael

It's easiest to check it with a flash-light

cossiecrew

th3 2 i have are cracked inside and out 1 has been welded on the outside the other hasnt but ive recently got 1 of a guy from here that only has it on the inside so thats whats gonna get used its just abit of a worrie last thing we want is it to come apart and fly off into the new t34

CossieCrew - Was the person who sold you the cracked one called Andy perchance?

My manifold has a crack in it too, has had for at least 2 years, and doesnt cause any chew at all

You can have them welded up as well if needed.

Have anyone used steel exhaust manifold in a Cosworth, do they generally give extra horsepower, and who makes them? Atleast in N/A engines steel manifolds gain quite a few bhp compared to the cast iron scrap.
