Broken Manifold studs.

I get a diesel like tick from time to time at idle, I think I found my culprits.....

So i figure I'll go ahead and replace the studs and gaskets. I'm just stumped on how to remove the broken ones

I might be missing it but I don't see anything wrong?


None the less, you'd have to drill and tap the holes for the broken off studs in most cases. That means removing the heads...Unless theres another way I don't know about.

If you look, the top studs on the furthest back cylinders on both of the heads are broken off even with the manifold. I imagine it is causing a small exhaust leak, which is giving me my sound.

Factory studs usually have holes in the studs/bolts do that they can be taken out in case they do break.

BTW I noticed that your oil filter has idiot instructions on it.

dude that made no sense...

Remove the manifold and hopefully you get lucky and there is enough stud still sticking out to get a GOOD quality extractor on it. If it is flush I have had good luck drilling a hole in the stud and then hammering a Torx bit into them to spin them out.

Took my manifold off today and realized that if I pulled the nut off engine mount bolt I could put a floor jack under that side of engine and carefully lift/tilt engine up and away so I had more room to work on it and the bolts were a bit more pointed at me....may help if you try to drill them out in the engine bay.

i hear that same deisel like ticking to sometimes when im warming up my truck. and i also have the same broken bolt but only on my side by the a/c stuff. i thought it was a sticking lifter/broken lifter. let me know if the ticking sound goes away when you fix the bolt/gaskets.

You have to miracle the broken studs out. Through 500 years and 6 billion heat cycles the stud is as strong as a pretzel and harder to get out intact than a compound full of Branch Davidians.

If there is ANY stud sticking out, don't start chewing it up with vice grips. Vice grips don't grip shit. Better to stare at the remains and wish it would start turning than attack it with stupid vice grips. That's a seriously clamped stud. I try to weld a nut onto what is left and then heat the living crap out of it--cherry red, don't spare the heat. If it's going to come loose, it will turn easily. It's not clamping anything so there is no torque--it's stuck. Don't try beefing on it or you'll break the weld.

If you do twist off the nut--or you couldn't weld one on, it's drill time. This isn't easy. You need to drill straight and true through the center. Keep using larger bits until you can pick the threads of the stud out of the threads of the head. A little heat will help. When that fails, you have to drill the whole thing out and install a threaded insert--Heli-coil.
