now i have used a felpro head gasket in my last zvh engine and my current zvh, i ran my last engine t34 @ 24psi and nitrous, gt25/40r 19psi plus nitrous, current engine 28psi plus nitrous and in 22000 miles i have only suffered one gasket failure due to det ( my fault hitting the rev limiter with nitrous which is a big no no) which no head gasket will handle..
my question is, is this problem only associated with the 1.6cvh many people running this gasket with no problems but there have been quite a few failures discuss.... i want to start running 30 or more psi i'll be on borrowed time trying to use that sort of pressure with a felpro gasket

Dont risk using a felpro, end of discussion.....

Oranoco

As above.

Made the mistake once won't be repeating, especially when the standard HG is so up to the job

SafeChav

Easier said than done, what other alternative gasket is there to run on a ZVH.....

A standard gasket doesnt have a large enough bore size........so on this occasion the "dont use a felpro gasket" isn't a valid answer.......

fast_ford_uk

why?????

nellrodd

Agree with safechav, Ive got a 1900cc bottom end and there is no other option other then a felpro. So needs must i guess.

You also have to consider your CR.
I split 3 or 4 last year the last been split at 25psi.
They fail between the cylinders first, if you look at the construction you will see that the fire rings are made of thin pressed steel but with a core of cardboard like material, as the cylinder temps increase the cardboard compresses and allows the pressed metal fire ring to collapse - failure.

So I then used a copper head gasket with some 2thou thick steel fire rings to reinfore the cylinder ring, the problem with that was it was very time consuming and difficult to fit and used sticky sealant, but worked until a bit of piston damaged it.

So I know have a new type of head gasket that uses a re-useable gasket meterial that doesnt use sealant and a set of 4 solid steel fire rings that I can get made to any bore size. So far so good!

i've had same issues with Felpro's on my old 1.8 cvh turbo. at that was never running more than 17 psi.

fast_ford_uk

so do you reckon they are ok for someone using 12-14psi at most

vroooom ptssssh

Because they seem to fail fairly easily between firing rings on CVH's, So I'd seek another alternative on a ZVH!

Fiecos Dan

i've had 1 or 2 fail on 10psi.

i wonder if its just a bad batch because 10psi is a complete joke

sas

My first Felpro was already fitted to my 1.9CVH and that took 28psi, CR 7.2:1 that gasket never failed, it just knocked the big ends out! That one was maybe 8 years old.
The rest were aquied and failed last year.

So what do you use now being that you have a 1900cc bottom end, i too have the same, so any ideas??? Ive been told by a tuner recomended on here that you have no other option than a felpro when you have this size bottom end.

my 1.9cvh was 82mm so i got away with the standard head gasket whats the size of the bore on your 1.9cvh?

nellrodd

The bore on mine is 83.3 mm so as far as i know its felpro or bust!!

Fiecos Dan

It was Hi comp tho,

but even so, no more than 200 bhp/lbft

kamylamy

Hi guys my head has gone should I use a felpro head gasket set??? My Rs is standard with uprated cam super chip vernier pulley etc, the question is if its safe to use or not wont be running more 12psi???

studabear

just use a standard ford/payen gasket.

Try gaskets for classics on ebay.

escoskmv

I had 2 felpro head gasgets fail on me boath blew between the bores there for I would not use them againe

kamylamy

i used a cometic gasket on my zvh from DS motorsport. might be worth messaging rs200dell on ebay and asking if he can get any more, was a few years ago now though.

kamylamy

Thanx a lot guys for all your help!! My car is only breaking 170bhp, I'm happy with that. Had it done at power engineering. There was a guy there called Ian bell rolling road technician he has now left does anyone here no we're he has gone?????!!!

kamylamy

Set my car up a treat very useful helpful guy knew his shit about turbos! Want to take my car to him when I get it set up, if anyone knows of him or were he works let me no. Cheers thats Ian bell from power engineering!!!!'

Dont ferriday engineering produce copper head gaskets for the cvh?
If not speak to si-tech about his reusuable ones.

zvh

the reusable cometic ones that simon sells are perfect for high boost i have one on mine running at 2.06bar no issues atall
also iff u do your home work on the felpro gasket its made for the american 1900 tall block which has a bigger bore size than the 1600cvh so they will blow regularly on a 1600 as there actually to big !! saying that i had a felpro on my zvh for 1 year it took 22psi then blew a lump between cylinders .the only gasket that seams to last in my experience is the cometic /sitech gasket and now at 2.06 bar still spot on

muz

If its a CVH use a Ford/Payen gasket. If its a ZVH use a Sitech with a standard head or a Ford Zetec gasket with a welded head.
