I know some have had good luck with the bars leak rad sealer but what is the opinion on bars leak rear oil seal stop leak? Will it work on rope seal or will it plug pick up screen and the cotter pin leak hole? Thanks

There is only one way to properly fix leaks.

I never use radiator sealant. My opinion is it's like pouring dirt in your radiator. If it plugs up a leak it plugs up the core too. Then if it plugs up the leak you can't depend on it to stay plugged. I either have a radiator shop repair the leak or replace the radiator.

It won't plug up anything, it's a totally different concept than cooling system stop leak.

It works by softening and swelling the rubber in a worn, heat baked rubber seal.

So to answer he question, no it will not help a rope rear main seal.

What may help though is to run the oil a little low. Trying to keep it at the full mark can be a futile battle. It will generally seek it's own level about a quart low.

Also be sure the crankcase vent is clean.

Miracle Fix in a can is only intended to limp a machine home so it can be properly repaired .
Re-core the rad .

I try something like that in my 1971 Chevy Vega and all it did was cost me $400 because it made the oil pump relief valve to stick and in turn blow out the oil filter gasket

Steve , I use LUKAS oil stop leak and just as you say it softens and swells gaskets and seals and it works great and I have never had a problem. My Mustang kept dripping and I snugged all pan bolts and rocker arm covers , was afraid to tighten further in case they squished out , so I added a dose of Lukas and the dripping ended. I had people say you will be sorry and lots of negative stuff. A company like Lukas has perfected their products and have been around a long time,they are not going to sell a product with a liability issue. On the other hand a rear differential seal is an easy fix, make your own gasket from a file folder, some blue gasket maker and you are good to go.

I had a worn out 01 Silverado I didn't want to spend any money on.

The steering rack was leaking pretty bad, boots torn off, full of grit.

I gave it a dose (kept topping off the pump reservoir) with Lucas PS stop leak.

It stopped the leak!

Sold it to a coworker, he put a lot of hard miles on it, never replaced the rack or did anything but drive it!

I've used lacquer thinner. Also used in transmissions that wouldn't shift up.

Saying that reminds me of something I had happen to me years ago. The weather guessers had called for a snow storm which we did get. So the day before I had fueled up a couple of the tractors so as to be ready for it. Well when it came the tractors would not run due to water in the new fuel I had just got. I could not get out of my place so I used what I had on hand. I had a couple bottle of rubbing alcohol so poured it in the tanks and in short time the ice blocks in the sediment bowls had melted and the tractors started. That was decades ago and I have never gotten gas from that place ever again

What "liability issue?" There is NO liability with these products, whatsoever!

All they have to do when you say, "Hey your stop leak product didn't work/ruined my engine!" is say, "You used it incorrectly. Not our problem." Case closed.
