Exhaust manifold install questions

[UltraImports]

I'm putting on my exhaust manifold for the first time this weekend and I know there are a few things I should do before putting it on. Can someone please walk me through what I need to do when putting it on. I have all the gaskets and tools, I just need to know what sealants to use, where to put it, what to torque the bolts to, etc. Any additional info would be great also. TIA.

This is by far the most simple thing to do on any car. You simply put the gasket on, put the manifold on and then bolt it up. Off the top of my head I can remember somethign like 30 ft lbs for the bolts (correct me if wrong)... how coudl you not know how to do this. Unbolt, take off, bolt up and thats it! No sealant or any bullshit like that needed.

I'd say it's simple unless some of the studs in the head break. Then it's a whole different story. Use antisieze on all bolts so they will be easier to remove in the future. I've also heard there's an oil passage behind the bottom middle stud on the head, so use some gasket sealant on it. As far as torque specs, 18-22 ft./lbs. for the manifold to head studs, and around 40 ft./lbs. for the manifold to turbo bolts.

I mean...I knew it would be easy, but I remember someone telling me there was a sealant I should apply before putting it on. So no sealant? Or should I get some just to be safe. Thanks guys. I know this sounds so newbie of me, but I don't want to f this up

what about when installing a tubular manifold? dont u need to support the turbo?

 

[candela]

no sealant necessary my man...
if anything use lock tight on the studs that go into the head and use anti seize on the threads that are sticking out of the head where the manifold bolts go. Its as simple as you think it is..

"what about when installing a tubular manifold? dont u need to support the turbo?"

Just curious but how do you ask this? There is no set of rules to do this shit man. if the turbo is lagging or falling or bending a line or something then hold the damn thing up!! its common sense dude!

No no no:laugh: .. i mean that ive heard that when installed, a tubular manifold can not support the weight of the turbo, so u must support it somehow

Wether or not the turbo needs to be additionaly supported depends on a few things. A small turbo with little weight can be easily supported, unlike a huge T4. Header material is also an issue. Softer steel, won't be able to hold it as long as a good SS header will.

I would suggest you give a little extra support, just to relieve the header of its' burdon.
