exhaust manifold question

hi to all

Well I have an leak where the manifold meets the engine .


I've tried everything , tightening the bolts , new gaskets and sealer.

nothing seems to stop the leak,and it's not warped.

any suggestions????

You're sure that the manifold isn't cracked where the tube meets the flange?

Yes I'm sure .
When I took the manifoild off I can see where it's leaking
