Exhaust manifold gasket change
Hi everyone. Ive got a exhaust leak from here. I normally just re-tighten the bolts and its fine. But its about time i sort it out properly put a new gasket and studs. Is just top piece easy to remove without removing heads, turbos etc. Its a gen 3 3sgte Let me know what im in for or if i need to take it to a shop Thanks  Sent from my CPH1725 using Tapatalk

You can remove just the turbo assembly (manifold, turbo ect) it should only take an hour or two, and I’d recommend using a multi layer metal manifold gasket when replacing, not a paper one!

Probably a stupid question.is there any adhesive or sealant that needs to be applied with the exhaust gaskets. Or just put the new gasket in and re tighten everything

I didn’t use any sealant or anything when I did mine a month or two ago, I just used a quality gasket, made sure all the studs were strong and not pulling out of the head when tightening (can happen) and torqued them up and it’s been fine

I’ve honestly never seen a manifold with those bungs on it before, someone correct me if I’m wrong but would they be for an exhaust sensor for each individual cylinder??
I guess they only need to come out if they are in the way of taking a nut off the stud.

Agree, my gen 3 definitely doesn't have those bungs either. Sent from my SM-J320ZN using Tapatalk

Dont want to complicate things but you might want to consider changing the 2 coolant hoses that are impossible to reach with the turbo in place - affectionately known as the hose from hell and the hose from hell on earth!

Also should all the manifold studs be removed for it to be able to be taken of? There a few vertical ones that are fully out, but the very ends are just spinning. Looks like the middle section of the stud is slightly wider than the ring. And wont pass through like the horizontal studs

You shouldn’t have to remove the manifold studs to remove the assembly.
I’m also about to also put a new gasket on my engine. Not sure what the besr brand gasket is to use.

The middle section of the stud you mention is the 'shoulder' where the stud 'seats' in the cylinder head. Doesnt matter if these come out with the nut as you undo it.
Im not sure how well you have examined what you have been doing before you dive in, dont forget there is an oil feed hard line from the cylinder block to the underside of the turbo, dont forget to undo this before you try to remove the turbo assembly.
