ford 460 exhaust
Ford 460 exhaust manifolds loosen and leak or crack. Ca smog problem with headers that are legal. Any ideas.

The manifold rarely cracks, usually it warps with the heat and breaks the cap off the bolts. Most common on the passenger side rear (#8 cylinder). The worst case is a crack in the cylinder head, which requires head replacement.
One note: when mine warped and broke the bolt, I was able to easy-out the bolt after taking off the warped manifold. Found a replacement cheap, but hold on to your wallet when you find 1) the bolts cannot be re-used and 2) a replacement set costs about $150.
Otherwise it's a pretty easy DIY project. HTH
