Permatex Leak Sealant

Part Time Pete · May 25, 2017

So I picked up some Permatex spray on sealer that is supposed to seal leaks in oil pans etc. (anything not pressurized). I tried it, and it just turned to a runny goo - it wasn't even thick enough to stick - just ran off.
I was surprised, because I figured Permatex has been around a long time and usually makes good stuff. Anyway, I cleaned it all off and went with good old JB Weld - success..

I use that for sticking gaskets on, put just enough on gasket and one surface to cover, wait until tacky, then stick gasket to surface.

You used the wrong tool for the Job! You didn'the say but sounds like you have a leak on an oil pan rail. I trust you made sure all the bolts are tight. I had a leaky oil dipstick adapter plug on my 7.3 Powerstroke engine. The o-ring swells and gets out of position. I slowed it up with some RTV, but when I cleaned it up good and sealed it good with RIGHT STUFF that was the end of the leak. Hasn't leaked a drop in five years.

That stuff is just for spraying gaskets mainly to hold them in place, handy to hold gaskets to a block while you lay on your back and get a couple bolts started. Years ago I used weather striping cement.

Many years ago I used a permatex epoxy to fix a hole between the chain case oil tank and the gas tank on a Bobcat skid loader. Really probably no better than JB weld. My gas would go down to a certain level while setting and the transmission oil level would go up. Sprocket had come loose and the chain had rubbed a hole. Musta' worked I sold the loader a year ago and both levels had stayed the same since.

I used to use the peanut butter from the C ration pack in the Army. Did a very good job of holding gaskets in place. The cheese was also good but you had to mix the oil back into it.

Billy, you kill me. I have a saying that I've done so much with so little for so long that i can do almost anything with nothing. It fits you too. LOL

Since the others went a little off-topic I'll add this:
Took my car in few years back, knew what the problem was--small drip drip drip from one of the heater hose connections in the engine compartment. The shop--same one I always used to go to--told me ya they can fix it--$850 tear out the dash, put new heater core in I'll be good as new. No, I don't think so.
Took hose off, saw small dent in metal tubing from the core. Scuffed it up real good, mixed up the JB weld and smoothed out the dent. Treated myself to a new hose while I was at it, with all the money I saved. Been driving like that for years. No leaks.

Well after 23 years in the military and many years of field service. You learn to make do. Use what you have on hand. Might not look good but it works.

I have a Ford Tarsus that the oil pan gasket pushed out and would leak a quart in ten miles. I got a tube of gasket maker(caulking gun size)and a can of brake clean to wash it off. I has not leaked for two years.

Nice line Uncle Tom! Hope you don't mind if I use it.
According to the label, this stuff was specifically designed for oil pan leaks. It probably would work well for keeping gaskets in place, but it definitely doesn't work as advertised.

A really good gasket sealer is Hylomar, Keeps head gaskets from sticking to the metal. It drys quickly while spreading with your fingers. Test it first, then follow instructions.
