Check your manifolds, boys

This was what appeared to be a solid manifold and it broke when torqing down #1. It didn't take a lot for it to snap, either. The pic's at a wierd angle but 3/4 of it had been compromised, as is evidenced by all of the black.

I am very glad it broke now as opposed to a more inappropriate time. :shock:

What type of manifold?

Casting defect resulting from the initial machining of the part? Was it ceramic coated or otherwise treated with anything?

That sucks!

I should have mentioned: b34 intake.

I was a little PO'd when it broke but the ramifications of it breaking while under load would be catastrophic. I got lucky.

Somebody used the intake manifold to lift the engine? :confused:

Who knows. It's 26 years old, anything could have happened.

Shit. My brother reported hearing a "crack" when installing our B35 intake

Looks like its been a pretty major air leak for a while. Probably got dropped at some point and cracked the flange.

You're making me thing I'll need to find a way to squeeze those intake manifold support brackets back in somehow. Dang it.
