broken exhaust manifold stud

all are the same. I recommend not using the sleeves just gaskets. it will let I breath a little better and less material to compress when you tighten the nuts. so there will be less chance of them breaking again. that's how I do all of my engines.

 

That's exactly what I did on mine.

 

Gunner we are talking about the exhaust sleeves that you would find inside the head ports, not the sleeves that go over the studs.
I'm saying this because a few get confused and don't order the studs sleeves only to have to reuse the old ones, also order the gaskets from Bully Dog in the same package they're not expensive.

 

what he said on the sleeves sorry I didn't clarify that.

 

Hi guys, I have a 5ek with a broken exhaust manifold bolt. The one that is broke was the short stud underneath the turbo. It was broke off flush with the head. I took off the manifold with the turbo still on it and luckily after couple hours got the stud out of the head. I got all of the other studs out without anymore breaking.

I did get all new studs, washers, and nuts from cat. I have searched the internet and can't find some answers I want. My question is do I want to apply never seize on the stud end going in the head? How tight do I get the stud in the head? Also I did notice I have those exhaust sleeves in the ports on mine. Is there a reason they are in there or should I just pull them out?

I did find on the internet the tightening sequence on the exhaust nuts and run them up to 33-43 ft lbs. If there is anymore info or tips someone can give me I'd sure appreciate it. I just want to get this done right the first time.

Thanks in advance

 

I just put them in finger tight or until they bottom out. Yes use never seize. Look at the studs, one end will be tapered. That end goes in the bolt hole in the head.

 

I always put high temperature never seize on exhaust studs and nuts. I've had to drill out and extract enough broken studs and bolts to last a lifetime. Anything to make the job a little easier for the next guy (who is usually me lol!)

 

Fix the broken studs immediately. When the studs break, they're usually not seized in the head; they've broken from fatigue. Remove the manifold. If you can grab them with locking pliers, they should back right out. If they've broken off flush with the head, then get someone with a portable welder to weld a piece of scrap metal to the end of the stud, and use it as a handle to back it out.
