Cracked exhaust manifold

[Rodd]

I was working on my dad pickup and found the exhaust manifold was cracked. Just an fyi this is an s10, so mods please leave it here for a while so the smartest guy's on the net (DTR) can give me their input. It is getting a lean code and wont pass smog and I can't find any in my area. I even had a couple of muffler shops looking and nothing. One said he was willing to weld it which will work but I need to get this smog'd next week and the shop can't get to it by then. I was wondering if I could use some hi temp RTF on it. Will that work?

Thanks again guy's.

Doubt the RTV would work long enough to put it on.

This stuff will

Unfortunately they are on the wrong coast for you but you could probably get it overnighted if necessary.

I would cover up the crack with some J-B WELD.

I have had several S-10's.. 2.2, diesel, 2.8, and the 3.1. They all crack. Drill the ends of the crack with a 1/8 inch drill bit to stop the cracking, then fill it with FS2.. or JB weld, but you will replace the JB every few months.

Ditto the JB burns off; stinks when hot, too. I tried it on the original manifold on the '67; switched to headers. Maybe the FS2 lasts longer, haven't tried it.

The JB would probably get you through the inspection then the shop could weld it up when they had time.
