Ultra Blue As Intake Gasket?

[FORZA-MOTORSPORT]

People have suggested using ultra blue copper gasket maker on the inlet manifold to head, as its gonna take 2 weeks for a new gasket to arrive, has anyone else used this with a 20-25pound boost application will it hold??

On the contry, a gasket is more likely to blow out that if it were siliconed. Use the loctite ultra grey though.

The trick to getting the ultimate seal is having both surfaces dead flat which most heads and manifolds should be from factory. Only if you've made you own custom plenum you MIGHT have some heat distortion if you've used youve made your own flanges.

As for holding boost and being reliable, I know of engines in the Uk that run 32lb boost and use ONLY ultra grey to seal the intakes and the exhaust flanges. All flanges are machined dead flat and there is rarely a problem.

Also one other thing, make sure the surfaces are very clean. Use prepsol or thinners to remove all traces of oil. Ultra grey seals so good that if you un-bolt it, you'll have a hard time getting it apart afterwards.

blue is the weapon of choice for many a GTR owner. Doesn't leak like the stock gaskets.

3 bond is even better again. Urethane based instead of silicon based.
