The Stovebolt Site Forums The Shop Area Interiors 64 leaking oil pressure gauge

I've had problem with fluid leaking onto my right foot (and the floor mat) ever since I had a master cylinder fail and replaced it.

I figgered the fluid was brake fluid leaking from the rear seal of the rebuilt M/C. So I replaced it and still had the problem.

Further investigation showed that it ain't brake fluid. It's oil. And it's coming from the area of the oil pressure gauge. I just discovered this yesterday while trying to get the fuel gauge working again (I found that the tan wire had broken and I'll be darned if I can find the other end of it.)

So...is the leak a common issue? Does the fitting just loosen up? Or is it more likely to be a problem with the gauge itself? I woulda done more investigating yesterday, but life got in the way.

Thanks,

Ray, I had exactly the same problem with my oil pressure gauge. Even after I tightened the fitting it would still drip. I then took the fitting off, put on some teflon tape, tightened her up and no more leak. You might want to give that a try. Don

Thanks, Don. I'll give that a shot today and report back to ya.

I had the same problem last year. I was driving home from work, it was night time and I made a pitstop. Got out and had oil on my shoe and pants. With mine, it was the gauge itself. Developed a little crack that dripped nicely under pressure. I tried some epoxy and it worked for a few days, then started leaking again. I installed an aftermarket gauge temporarily. It's been over a year now and the temporary gauge is still hooked up.
