I have a sealing face that is a little worse for wear. It's where the heater pipe bolts to the cylinder head (on the drivers side).

The heater pipe flange was rooted, but I cleaned that up with a flat file. The face on the head is a little corroded....and this I can't change.

I put 2 gaskets between the flange and head. Is this acceptable? Or will this leak?

It was leaking with a single gasket.

Not sure if a 2nd gasket is going to help. You might get away with a gasket & some RTV silicon on each side though.

How deep is the pitting?

hmmm...my theory was that the double thickness would help squash into the pitting to create a seal.

The pitting isn't deep, but it's no 'flat face' I can only speculate about the depth.....at a guess maybe .005" - .010"

Is this on JAM? And the head's just been all painted and looks yummy?

Because I was going to suggest a better way to go is to get the pitting brazed up and machined flush. What a PITA huh

What about building up the mating face with some DevCon ?
(Engineering supplies....)

should be heat-resistant to about 1700'f ........

you can file it, shape it, whatever.... just give it enough time to go-off ...

Its what i did with my Thermo housing on the last 202 head i used.... hasnt leaked since...

Anton, give it a go with 2 gasket & some silicon, i had the same problem on Pen's Clubman it worked on it.

Doogie

Hay, it's not about the car, it's not about the venue, it's about the people that come here. Peter Dwyer, Mayor of Hay NSW.

as of last night I have put 2 gaskets with copious amounts of Loctite #4 gasket goo. I am hoping the hard setting goo, plus the 2 gaskets will be enough.

In theory I should have looked at this when the head was stripped bare.... I could have had that face machined........

Devcon will be the alternative I think. Heard about it years ago....never used it (yet).

Cheers for the feedback guys.

Bend the tin flange up a bit at each end, it's probably bent the other way from over-tightening.
I uas Loctite 515 Master gasket on all the water joints now- it's magic stuff. Would want to be for $18/tube, hey.

It's $25 a tube west of blacktown!
But it is good stuff I'll agree.

It's also the reason my gearboxes don't leak. For a while, anyway.

well...the double gasket and Loctite #4 sorted me out. Took JAM for a rap this afternoon and no leaks

mmmmm.....sniff sniff....you smell that?? I can smell rego
