EA81 Exhaust gasket

I can't remember whether there was one or not...
For an Ea81 the exhaust does not connect to the head.
There is a "spacer" Used to connect to the pcv I think.
My question is, I have a gasket for the spacer/ exhaust.
Is there a gasket between the head and the spacer?
I know that i did not get them in the vrs or the bottom end rebuild kit.

Cheers Cam

no gasket between the head and that egr feed block thing that featured on later EA81

Ok. Cool.
Should I use some gasket goo? Or a metal to metal seal?

Hang on am I missing something here? The exhaust doesn't connect to the head? I think you'll find it does and there are gaskets between the exhaust manifold flanges and the mating surface of the cylinder heads. Yes use some gasket goo but not a heaping pile, and don't forget the gasket where the Y pipe section joins to the rear section (join should be pretty much under drivers seat) if you ask for this gasket at parts place they will give you the smaller gaskets for the cylinder heads-Y pipe connection. The middle one is exactly the same shape only bigger.

What is this egr feed block thing you speak of Jonno?

*Edit* reading again we could be talking about 2 completely different things, ignore all the above if we are:rolleyes:

I think we are Sam.
This little egr block connects to the head.
Then the exhaust connects to that.
On the side of the egr block there is a place to screw in a part of the pcv system I believe.
Pics tonight after engine is in hopefully one piece.

The EA81 in at least the last run of Brumby ran shorter length pipe section from head to horizontal runner of exhaust to make up for the cast and machined flat adaptor/spacer that bolted directly to the head both sides. The LHS spacer recycled a bit of exhaust back up to a reed valve thingamyjig and onto egr or something. Not exactly PCV stuff more egr. Stil, no gasket !

Thanks for that steptoe.

Ahh I think I know now, my current engine has no EGR but the twin carb does, and a little tube coming up from drivers side cylinder head into the EGR? with a little heat shield and everything.
