Hi friends:
I replaced heads and gasket on my 2003 grand Caravan. I bought 2 new heads.
When I though everything was ready I started the engine and I heard some unwanted exhaust noise. I checked the manifolds and everything is OK.
The heads I used have a PCV hole in it. But the car doesn't have that connection in the head. The PCV is done in the valve covers.
So I have one extra opening in each head. Can somebody tell me where it is and what I need to plug it?
I hear it, but do not see it - does it have tread in it and what size?
Thanks for your help. D.

 

Those are EGR ports and you need to put a plate and gasket to stop the leak.

 

Is that to fix from the outside please? I still couldn't figure out where they are.
Are you talking about 1 hole per head or more and on what side - the manufacturer says at the end. Is that plate to glue with the gasket or is is something that has to be screwed on please?
I have put the heads (old and new ones) together to see what it could be, but
I didn't see no difference. Now the engine is back in the car. I really need more details. Thank you.

 

The plate should be bolted to the rear head,ansd yes you can did it from the outside of the head.Do you still have the old cylinder heads?

 

Yes I have these. They had no PCV or EGR holes in it. Now it seems that only the 2003 version came without? I guess I will need to make these covers myself,
I am on the Islands.
The heads are here, if someone passes by - he can have them. Each have 2 small cracks, easy to repair with TIG.
