Any exhaust leak repair goop that works?

Paul007 · Apr 15, 2017

My rusty old 1959 gas Perkins blew half the exhaust gasket out of the front cylinder, I've been using it that way for 5 years. I've tried several times, with the engine hot, to loosen any of the manifold bolts, no luck. I use it often so don't want to open a big can of worms by breaking any off (holds the intake on too I believe). The leak is easy to get to, I tried some muffler patch which lasted about 5 minutes, then some other supposedly better stuff from the auto parts store that lasted about a day. I've heard of guys using furnace repair glop. Is there anything that actually works? I just put a new muffler on so now it's sounding pretty loud.

Flatten a piece of solid copper electrical wire just enough to drive it into the gap. (might work). Jim

As you probably well know an oxy-acetylene torch is the go to tool to heat up stubborn exhaust
nuts/studs/bolts. But then not everyone has access to one. Do tell what kind of a rig does this
engine reside in? How much HP or CID are you talking? When pulled hard a gasser produces a
lot of heat, I'm wondering how effective Jim's suggestion will be? Worth a try.

Thanks for the replies.

It's a '59 MF tractor with a FEL and drag box in back. A work horse, nothing clean or collectible. I haven't tried the torch, I have so much work to do on my property I just can't spend the time get the intake and exhaust off, plus whatever else is in the way and get potentially broken bolts out of the head, not for just an exhaust leak.

I like the copper wire idea, going to try that. Not sure if I can get a hammer/drift in there like I can my finger. If that doesn't work I'm just back to living with it. I guess if there is no miracle goop that holds up to exhaust heat.

Letting it continually leak will erode and ruin both the head and the manifold, got time for that?

Nope, it will go to the bone yard. Thanks for asking.

When I was in the Guard. We used a paste on the 151 jeep exhaust. It looked something like JB weld. When put on correctly we never had a problem.
Might try that. Stuff the hole with JB and let it cure.
