Re: Passenger Exhaust manifold turbo studs NOW WITH PICS
I certainly won't doubt Bob's real world experience with bolts vs. studs. I can only explain what worked for me. I replaced the studs with bolts when I went through this same problem with one of my studs breaking off a year or two after I bought the truck and was upgrading to a 20g turbo. I ended up buying a set of carbide drill bits from Snap On and drilling out the stud, then re-tapped it. At that time, I put in hardened allen bolts to hold on the 20g.
When I installed the PTE kit Todd sold me 4-5 years later, the bolts I originally used on the 20g were still tight and I had no problems getting them out. I bought new hardened bolts and put them in. With the PTE kit, the allen bolts made life a lot easier to get in (probably with the stocker as well). From my experience only, I would do it again.
