Exhaust manifold glands

[Chuck Sea/Tac]

I don’t use them anymore. I also don’t have a manifold gasket leak problem. So I think it’s a waste of time. IMO

Reminds me of the old adage "You can lead a horse to water but you can not make him drink"

Me too. Besides, I have an Autolite waffle manifold that hasn't sagged in all these years, it probably won't with my 5 or 6k miles per year either.

Follow up report - the new exhaust manifold finally arrived (five days late, thank you FedEx), I dry fitted it with the old intake manifold and the assembly was straight and consistent within about 0.003". When I fitted the assembly to the block with glands installed but without the gasket it snugged down just fine. So on with the gaskets and tightened to 35 ft-lb. We'll see how it runs once I get the gooseneck back on (had a radiator leak I'm working on at the same time, took this opportunity to clean up the gooseneck.)

Be careful installing it as the ears on it are fragile. I have snapped them off more than once I think.

Thanks. New gaskets, and I ran the four nuts up about a quarter turn at a time. I also figured that while tightening the two manifolds might want to move independently of each other so I left those two bolts loose until the manifolds were seated. It felt good.

I think J Franklin was talking about fragile ears on the water outlet (aka gooseneck). Not that you can't snap the ears on the manifolds, but it's much less common.

Hmm, OK, Thanks.

The two manifolds need to be securely bolted together before you assemble them to the engine. You need to bolt them together, and mill the jointed manifold surface straight and flat.

There's a decent amount of weight hanging off the intake and exhaust manifolds. You'll have trouble keeping them sealed against the block with your method.
