Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default Exhaust Gaskets Part Number

Checking everything out before I go take my class B road test and discovered small leaks where the exhaust pipes hook up to the exhaust manifolds. I called both local truck shops and NAPA and of course they couldn't find anything listed. Does any one happen to have the part numbers for the triangle gaskets at the exit point of the manifolds?
Thank you.

My 80 doesn't use any gaskets there, just a bulge on the end of the pipe that is squeezed up into the manifold.
I have read where some use a gasket around the pipe that squeezes up against the manifold the same way.
HTH, Dave

Thank you.
Have you tried tightening them. Might want to loosen them first and make sure they are retightened evenly. I've had mine off and I don't recall a gasket either. Just pipe with a flange and manifold.

Thanks Dave. I guess I'll remove the three bolts (after I spray them with PB or Deep Creep) so I don't shear them off and take a look.

John that sounds like a good idea too. The bolts looked a little (being kind) rusty. I just don't want to shear them off and have to drill them out. Do they thread into the manifold or do they have nuts on the upper side?

they are bolts and nuts,so no worries if you wring them off.
I think Finn may know the numbers for the gaskets,i replaced them once for him.

Mine had bolts with nuts. Good Cat bolts. Soak them with PB Blater and use impact.

Mine are bolts with nuts and lock washers on top.

Well I sprayed them down real good with PB and tightened them up. No leaks.
