Leaking Intake Manifold Tips

[AngryRB]

Ive developed another intake manifold leak, the first time was with the stock gasket but this time its after replacing it with a new one.

This is really frustrating because with my setup with a topfeed fuel rail there is almost no room to even take the bolts off is rediculiously time consuming.

Does anyone have any tips/advice on fixing this reoccuring issue, the new gasket was degreased and the surfaces were all clean and bolted down tight,

so should i use some special bonding material to make it a tighter seal or should i/could i weld the two halves together permanently?

Did you use any gasket goo when installing the new gasket? If not, I'd pull it apart and put some on both sides if the gasket and see if that helps.

i did originally but it looked like the gasket goo was allowing the gasket to squeeze out of place while i was tightening it up, so i degreased it and dried it

is the manifold mating surface completely flat

I ended up selling my r32 after the 3rd time this happened, when it first happened i had the manifold machined so i can only assume the head wasn't straight which makes sense as the previous owner over heated the engine which cracked and warped the head a d instead of just replacing the head he spent 2k getting the head welded and shaved lol

So yeah if the 2 faces aren't flat you're going to have problems and make sure you use a genuine nissan gasket not some ebay junk

yeah i checked both faces and they were perfect, were talking about the 2manifold halfs here not the manifold to cylinder head gasket , but perhaps i should take that one off and check too,

the gasket between the two halfs is a soft rubber gasket and theres nothing but the clamping pressure to keep it in place, i guess they didnt plan for it to handle 400hp when they designed that part.

might end up just welding the too halfs together if possible.
