How High Can A Guy Raise The DS Engine Mount For Exhaust Manifold Replacement? (1 Viewer)

[harrydunn]

Making good progress on DS exhaust manifold replacement. 3 of 8 nuts off so far. Well, nut and studs--they are all coming out together. I'm wondering how high I can raise the engine with only the DS mount loose? Thoughts? I'd say I'm about 1.5" so far. And, I'm gonna lose that fingernail. She's really swollen. Got that nut off though so I'll take it.

One of Otramm's tips is to stick a 2X4 in that gap. Here's the video: Otramm's 100 Series Exhaust Manifold/Header QuickTips

So an inch and a half. Gotcha. I'd say I'm close to that. I'll cut some scrap and stick one in there.

And loosen the fan shroud or you may crack it.

Good idea.

That’s what I did. Works great.

Well, got 'er off. Not too bad, all things considered. This isnt't my DD so I took my time working on and off on it today. All of the studs came out with the nuts so I'll be ordering those up. Classic crack on #1. I hope the install is slightly easier than the removal!

Nice work. Are you replacing it with a stock unit or are you upgrading?

 

[harrydunn]

Oh, probably just stock. I'm not convinced yet to go with DTH.

I’m among the few that did not “upgrade” to DTH, etc, and instead installed new stock manifolds. I have no regrets...and no cracks yet.

Ha! One of my favorite GIFs.

Why not have it welded?

 

[harrydunn]

Eh. Too many stories of it not holding. I actually weld too.

Question. Since all of my studs came out of the head, do I just install my new studs until they bottom out?

Yes. Then, after you get the new gaskets and manifolds on, torque the nuts to 32 ft-lbf...if you can get a torque wrench in there. With a combo of extensions and wobble joints, I was able to get a torque wrench on 7 of the drivers side nuts and all 8 of the passenger side nuts, but YMMV.

I went through a similar search for space last year replacing all 3 motor mounts. You can loosen the rear mount for another inch or so if needed.

 

[harrydunn]

Anybody know the socket type to use for the studs?

 

[harrydunn]

Looks like Female Torx E10. I've already got one I think.

Wouldn't exhaust/muffler putty cover that crack and save you all the headache?

Wouldn't last long, if at all. Even welding the manifold crack is often an ephemeral fix...
