Stripped Exhaust studs

my89Supra · 07-31-2011, 04:54 PM

Looking for best solution to repair stripped exhaust studs. I see DriftMotion sells a helicoil repair kit and another company called Time-sert sells thread repair inserts.

Anyone have experience with either of these or have an alternate suggestion ?

Also, is it possible to remove the exhaust manifold with the turbo intact (disconnecting oil and water lines of course).

Thanks for the help.

Yes they work, but the material on the head is sometimes beyond being able to hold even a heli-coil. The drift motion kit is nice because they did the shopping for you. You could buy it yourself all separately but I doubt you'd save much. There really is no other alternative beside replacing the head.
You prolly could leave the turbo on but I would take it off and give it a good cleaning and inspection while it's easy.

Thanks for the feedback.

The DriftMotion kit includes oversized studs so I should be okay there. I'll probably see about rebuilding the turbo if only to replace the oil seals as the car burns oil when the turbo kicks in hard. Probably a good idea to play it safe and have the exhaust manifold shaved too.

Thanks again for your help.

IIRC the kit offers acouple different sizes? maybe not, it's been awhile since I read on the subject. Altho I do remember the guy who makes them said he only put a 5 dollar mark up on it. or you could do what I did for a stripped exhaust bolt.. concrete lag bolts. what? don't look at me like that. ....
