Hey folks, I am swapping out my engine for a rebuilt one soon (doing cylinder head at the college right now). All manuals (AllData and Chilton) say that intake manifold bolts may not be reused. I just called the dealership and they said Chrysler discontinued them. Can't find anything online. Would it leak badly, if I reused old ones? I understand that they are probably torque to yield bolts, but what other option do I have? Dealership did give me dimensions (6mmx25mm - 1.00 pitch). Thanks!

 

I can't find anything about the bolts being tty. Personally I would use them but when I needed a couple bolts for my DOHC I got them at Advance Auto.

Just be sure to torque them correctly and they shouldn't leak.
Intake manifold to head (plastic) 105 in/lbs
Intake manifold to head (aluminum) 250 in/lbs

 

Thanks for your advice!
