2005 WK 5.& Hemi Exhaust Manifold Torque Specs?

Hey there guys, just finished up with a complete, both exhaust manifold/gaskets/studs project on my 2005 WK 5.7L Hemi Limited. Just wondering what the factory torque specs are for the manifold studs. Ive got them to about just passed snug right now, and they definitely leak still.

Thanks!

According to the service manual :

Exhaust Manifold to Cylinder Head : 25 N.M 220 In Lbs

Did you changed your manifold because of a leak/broken bolt ? What was the symptoms ?

Yep, my right (passenger) manifold leaks. Sounds like a Diesel. One project I'm not doing looks tight in there but while I was installing the JBA Upper Arms and had the fender liner out a few days ago I saw that a bolt head was snapped off...so at least there is a stud. I drive maybe once a week, maybe 100 miles...so It's on the back burner for me...Call around in Dec and have it fixed in January. What does a shop typically charge for this service? Looks to be a real PITA to get too on the 5.7L.

I changed out the Manifolds/Gaskets because of leaks on both sides. The passenger side had two broken bolts, the top and bottom at the rear of the manifold. The driver side had one broken bolt at the top rear of the manifold. PITA for sure. Pretty pissed that it's still leaking to be honest. Will hopefully have the time to get back in there next week.

Not a good start to owning the vehicle, we'll see I guess.

So you probably have a warped manifold if it still leaks!!!!

So how bad was the right side (passenger) doing it yourself?

I replaced both Manifolds so I don't think that a warped one is the problem.

Passenger side is the easier side. Hardly any room on the Drivers

What all did you end up having to remove to get the manifolds replaced? Did you have to raise or lower the engine at all? Mine are leaking also and I'd rather do it myself but for this one I'm thinking I'd rather pay someone. I can barely get my hands in between the manifold and frame on the drivers side, and can't see how to get all the studs loose much less maneuver the manifold out of that space. And I'd be SOL if I broke a stud off in the head.

Thanks!

Also sucks that yours still leaks. Did you get it fixed?

If I had seen this thread earlier, I would have recommended you buy the LX manifolds. They're more efficient than the stock WK's, but you'd require slight head pipe mods. Probably help the fuel economy and the performance a little. Here's a thread I did on the differences:
