Exhaust leak parts

[adj]

I have discovered an exhaust leak on the right manifold due to a broken rear stud. Do I need OEM parts or are there generics available(gasket, stud and nut)?

I had both sides fixed about a year apart from one another. It's no problem fixing the leak - the problem is extracting the broken studs. You will break some studs so don't be too disappointed. I just changed my left side, new gasket and parts, labor and all, about $700.00. The welder needed time and the shop needed time. I already posted the gory details here someplace in another exhaust leak thread - look for Exhaust pipe wiggle, normal?

On my 2004 LaPalma with the 8.1 engine I've had both exhaust manifolds replaced after a few times of the original RV dealer tightening them for leaks. They were replaced under warranty by a good Workhorse dealer where I live. They had to replace one head because when the machine shop was trying to remove the bolt they drilled through the water jacket.
I'd suggest going with an after market set of headers, Banks or Thorleys, and be done with it.

Fortunnately the welder that removed the broken studs also removed flush broken studs (2) in the exhaust manifold itself. It cost me perhaps more than I wanted to pay but we saved the heads on both occasions.

Now on a Winnie, the left side has a heat shield that protects the hydraulic hoses from the pump to the devices. The shield had to be cut off, modified and bolted back on all which took time.

I was cringing about my concern that we'd be doing a cylinder head but it worked out.

Generics are available and a lot cheaper than the OEM parts. I haven't checked for the stud and nut but Advance Auto Parts has the donut gasket.

You should have checked my web site. 15170385 - GM or F31731 - Car Quest...

Well, all this is discouraging. We are full timers and if I have to take to a shop we will be in a motel. I had visions of performing this job myself by removing/reinstalling the exhaust manifold.

Advance Auto Parts:

You will have to call them about the donut gasket.
