RS-Rikki

My zvh has had a new head all ported ect but I have built it bk up and it's blowing out the manifold I have tried two new gaskets but my old one has the metal rings but I tried all different combinations of gaskets but it just won't seal any ideas

warped manifold?

Have you tried a new genuine ford gasket?

I've reused my genuine ford gasket 3 times now. (i'm tight)

which manifold?
if it's the exhaust may i ask how the breather on the front has been blocked?
i had an issue with a plate and three bolt block for the breather (dean wall block), when the erst manifold was fitted, one of the bolt heads was keeping the manifold from sitting back enough to seal properly.
with the head being cleaned up the face may have been machined and bring mani into the block a little more.

Just a standard escort rs turbo one it's blowing on middle cylinders at the bottom doing my head right in

back to my question, what method of blanking breather has been used?

It's like a sliver triangle with bolts how did u get round it

remove the plate and use a core plug instead

i just ground the head down on the bolt, core plug would be better though.
infact i doubt the bolt had much left to actually hold the corner down, there is no need for three anyway.

Hmm ok I'll give it ago n that should be ok do I have to do alot or just a little bit

like i said, i ground loads back, just take the bolt out might be easier, if you find it spitting oil out, fit a gasket or a little sealant.
