Looking for a good intake manifold for D2 ser# 5U10061. The one currently on it leaks between the pony exhaust and the diesel intake.  I assume the exhaust tube is cracked. Any leads would be appreciated. Thanks.

The later 5U had a copper pipe with an expansion bellows on one end, inside the intake manifold, That b allows could b e cracked, or the end seals could be shot, Take the ends off of the manifold and take a real hard look at this copper pipe. You might b e able to fix it with silver solder, or maybe it just needs a gasket or two. There's a couple keeper half-rings that hold it in place and they are really easy to loose when you take it apart. Be careful!

Some place I have one of these copper pipes, but it didn't turn up when I cleaned out the shop and organized parts. If you haven't got it fixed by now, try a private message to Jack and I'll take a better look for it.

Good luck,

Jack
