EGR Fun

So I have a remanufactured head sitting next to the old head, and I'm swapping parts from one cylinder head to the other.

The EGR came off the old head and looked like it maybe had a gasket on it at some point, or maybe it was just RTV'd on there. The head gasket set I got has two metal gaskets that appear to be for the EGR.


Do I use one or both?

Any RTV here?

I'm very confused, as to why there would be two gaskets, and why they are metal.

One of them has a smaller diameter hole than the EGR valve or the cylinder head hole.

Can anybody help me please?

2.3L Duratec, 2006.

Ron, thank you for your response. I've been researching a lot about this repair on this forum, and you are a great guy for all you do for everyone here. Thank you sir!

There are two EGR gaskets because one is for the 2.0l engine(smaller diameter one) and the other for the 2.3l, the gasket set works for either engine size

You can use High Temp RTV, if you have some, but not required

Exhaust gases can run 1,200degF so metal gasket is best, boosted engines can run 1,500degF

Exhaust manifold gasket should be metal clad as well

OK, thank you. I put the one in that is the correct size holes, if that makes sense.

Do you have any place to point me for valve stem seals? The new head apparently does not have them installed, which I am pretty disappointed about. Looks like a lot of fun

If not, no problem, thank you again for all you do for all of us.

Never mind, this is a motor with a timing chain, not belt. Therefore, there are no cam seals. I was all confused between valve stem seals, cam seals, etc. but I called the remanufacturer and the valve stem seals are already in (that would be strange if they rebuilt the whole head without putting new stem seals in, hence my confusion) and since it is a timing chain and the sprockets are internal, there are no cam seals.
So the next step is to finish cleaning the mating surface then install the head!
