R33 Intake Manifold Leaking Coolant Onto It

[central coast person]

I have been noticeing build up of coolant on the ports at the front and middle of the intake manifold as of late and it built up so i decided to check it out.

With the intake manifold off i cant really notice what has cause this although i can see it has leaked directley above the channels where the coolant goes inbetween port 1 and 2 and port 3 and 4, ...... 5 and 6 are fine. I dont think these intake manifolds are common for warping and the feeler guage shows it fine.

The only thing i can put it down to is orange goop was applied only around the coolant channels on the gasket and i though this might have caused the leak of coolant as the workshop manual says you dont need to apply anything as its a crushable metal gasket for the intake. A non genuine gasket was used aswell =/

Has anyone had this problem before? Should i re apply something there or should it just be crushed?

The engine was rebuilt 25,000km ago and not had a problem, the coolant only started leaking 200km ago ......

You can see where the coolant has stained

I fell for that trap on my first build, metal gaskets got told not to use any sealant. Leaked.

Now i always use a thin smear of sealant. Never had an issue

Hey Jez, What are you using with metal gaskets, i still feel the need to put something there..... im now being told to use Permatex Aviation Form-A-Gasket No. 3 Sealant

formagasket works for me everytime. goo it up and slap it back together

Permatex Aviation Form-A-Gasket No. 3 Sealant IT IS!!!

im changing everything anyway all the gaskets, 8 coolant hoses/heater hoses around there the 4 air hoses and 13 bolts and nuts on the intake manifold and the 9 on the plenum just to be safe
