Exhaust Manifold Question
I have a 92 SC300 and my exhaust manifold bolts always come loose, I've tried LOCKTITE, and I was wondering if anybody else has the same problem.
The bolts that go into the head come loose and the nuts that tighten the header also come loose. Should I buy new nuts and bolts, or WTF?
I would greatly appreciate everyones input, it drives me crazy that I have to retighten everything every 6-8 weeks.

No, I have a stock 2JZ-GE. I've been thinking that maybe my head has been stripped and I need to rethread it. If I do so, would I need larger bolts? Has anybody done this in the past or had the same problem?
I have an extra motor and I've also consider rebuilding the other motor and just dropping it in, but it seems a little too much just to fix an exhaust header problem! Or maybe I could just rebuild the head and swap them! I don't know!
Everyones input would really be appreciated!
Thnak you

If you feel the bolts are too loose in the head, you could always install helicoils... any auto parts store sells a helicoil kit with correct size drill, helicoils and tool for little $. However, seems to me that if you can torque the bolt down in the head without it stripping, then there is not a thread problem. Honda makes a great concoction in a tube called "Hondabond"... put some of that stuff on the threads and I can virtually guarantee you they won't come loose.

Thank you everyone that offered suggestions and I wanted to let everyone know what the problem is, my head is stripped and the bolts keep sliding out. So tomorrow, I will be attempting to fix the problem with HELICOILS (thank you philauldridge) and I will post a thread on it.
Once again thanks for all your suggestions and help!
