i got a s/s manifold for my erst. fitted it sunday n already blown the gasket from the bottom of number 1 port! i used a good quality gasket n don't think its a problem with the head face as my cast 1 never had a prob! so thinking it might be the manifold is warped! 1 of my mates jus said use 2 gaskets but i feel this is a bodge. so wats my options, get the manifold skimmed n new gasket?

 

get the manifold face skimmed and use a new gasket.
if this blows again, you may need a little paste, but only a small amount though.

 

Had exactly the same thing mate!

Fitted SS manifold with a 'motorfactors' CVH Turbo gasket and it blew it instantly. I then got an original Ford gasket from Matt Lewis Motorsoprt on t'internet...and it's still holding fine.
There was quite a difference between the gaskets. The original one has solid 'Fire Rings' around each port and the cheaper one did not. The rings would appear to stop the gasket compound material from being blown out...

That's my theory anyway and it worked for mine! Just out of interest which manifold have you fitted??

Hope this helps!!!

 

its just a second hand 1 i bought off oddkidd's forum! direct replacement for the cast 1!

am i right in saying the original gaskets are payen?

thanx for the help!

 

Fuck thats probably why ive blown 3 manifold gaskets in 3 weeks on my recently built zvh, off to ford for an original

 

as said mate try an original gasket.

 

Hi mate.
Not sure od the brand of the original gasket, however if you can see an original one and an aftermarket one side by side you'll notice the difference....
I'll try to find some pics!!

 

Right.... Have a look at the pic on this link and hopefully you'll see the fire rings that I mean, in comparison to an ordinary one. This is the gasket i'm using, just got it without the stud kit!

macrs, where did u get it mate?

 

Hi mate. I got it from Matt Lewis Motorsport as in the fleabay link. However I just phoned them to order it and they were no probs.

 

spot on had same prob !

 

chances are the manifold is warped if its been welded round the ports, but a ford gasket might fix the prob

 

the autospecialists one i bought was warped i discovered after it kept blowing......for sure the ford gaskets with the fire rings are 100 times better, mine used to blow the aftermarket gaskets constantly.

 

Yep... Mine's the Autospecialist's one too and is prob warped! At least my original gasket is holding now...famous last words?!?!?!?!

 

i got through so many after market ones
payen are the ford ones

 

well i ordered 1 from ford! pick it up 2mora!. fingers crossed

 

Nice one!

 

fitted the ford gasket and guess wat...........................it blew straight away!

so today i stripped it all out again n sending the manifold for machining! checked it with a straight edge n it is bad! n defo looks like an autospecialist 1. so gotta get another gasket. but hopefully wen its back from machiners my calipers will be back from powdercoating so can fit all at once!

 

Cack! Sorry to hear that mate...would have been nice if it was an easy fix!

 

does any one recomend the auto specialist manifold. i was looking at it today any almost bought it are the power gains as big as they say.

 

quite a few tubular manifolds are slightly distorted on the location face
ive just skimmed and lapped one so it is dead true
more risk of fatigue if you clamp a distorted manifold on the head

 

i could never get mine true

always leaked a little

o ringed it in the end

 

thats what happens when the pipes are welded up and the flange isnt bolted to a scrap head lol

 

i wouldnt know how it was made


but

going off ava standards im sure it was done correctly

as there work is awesome
thats why i have another of there creations

 

im sure it was mate but thats what happens ,ive made a few now and never had a problem but being a welder sort of helps lol.
how far off is your car from being finished??

 

miles if i dont get to work soon

car is on the back burner while im out of work (again)
it might be sold with how things are looking at the mo

i will be doing my best not to tho

 

sorry to here that mate, its a real shit time at the moment for a lot of people including myself ,the wifes been in and out of work all year and its really taking its toll on the car fund.

 

where the bolts r on my flange wen straight edge is up against it they r perfectly flat! it jus warped between them. on the gaskets i blew it looks like above and beneath every port was gonna blow eventually!
