Default Problem with EGR gasket. Coolant leaking.

Hello guys,

Hope you all are good! Today I come to you asking for some help. I have a problem with my Forenza 2.0L 2006, it is leaking coolant from the side of the head, through the EGR gasket. I have replaced this twice and same situation. There is always a drop of coolant, over and over. I have cleaned both parts very well, the side of the head and the EGR base. For the first one I have installed the gasket without any kind of silicone of adhesive, then the second one I have tried a new gasket with grey silicone (previous two gaskets were made of asbestos), also, I have made myself a new gasket but using 1/16" vellumoid material, basically copied the original gasket and made it, and for that one I have use Permatex® Indian Head® Gasket Shellac. I left the car in the garage for more than 24 hours for the shellac to dry but same situation.

Any advice how can I fix this problem?

Thanks a lot.

I assume you have checked the aluminium adaptor for any corrosion or cracks.
I can't help really, but for any Forenza/Reno owners thinking what bit, this bit....



I'm assuming again that water is only sealed by the black rubber ring part of the gasket.

Another pic, just for reference.




Edit: This pic is listed as 2006 model but shows the slightly different adaptor and gasket fitted to earlier models. The appears to be no accurate drawings for the later type.

Hi Darrell,

Thanks for the reply. Actually, that rubber "o ring" seals oil. Water is seal by the center of the gasket itself. Adding another picture with that part marked.

Thanks.

I get ya, think that's the oil return from the cam cover.

Correct Darrell... That is the oil return. BTW. I just removed the parts again, the EGR base from the head. "Looks like" the EGR base is a little bent. I just measured with a metallic ruler and it seems to pass light about the middle of the piece (basically where it is leaking)

I think we have to take the piece to have it "brushed" (not sure it that is the correct word)
