OT: Do any of those "engine stop leak" additives REALLY work?
Posted by: rnch ()
Date: May 04, 2012 02:42PM

my ancient lincoln town car has developed a small oil leak from what appears to be the rear main seal area. Just a small spot abut the size of a coffee cup when it sits long enough..not worth tearing the engine apart to fix.

Any recommendations of brands to try?

In the mid 80's I used some"Beasung Seal". Don't recall who made it. It was very thin, lik H20. One round did the job on a 4 cyl, 2.5, Buick Skylark.

Some do. I have one like autoRx that has esters that clean thngs up and begin to soften the seals. Then a good oil can get to tham and continue the process.

I have yet to see an additive that repairs worn out parts.

Viagra will repair worn parts, just ask Bob Dole.

Having owned at least a dozen cars in the free to 500$ price range. I will say sometimes they work and sometimes they don't. Worst case is you wasted a few bucks. I've used them on cars that weren't worth spending a nickle on and I was going to drive them till they totally died. If that sounds like your lincoln, go for it, If it's a car you intend to keep for a while, fix it right. Just my opinion.

Nothing will repair worn out parts, but a seal softener (actually in the industry we call it "seal swell") can return some of what has dried out over the years. Really effective on steering rack seals, transmission seals, etc. the main engine seals are above the oil level, so only get splashed instead of soaked, but often can be softened.

You want one with "ester" in it... swells seals the best..

If it is a 5.0 fuel injected engine ala mid 80s (till the end of 5.0s) have you checked the PCV valve and screen Under the valve?

While it is not a stop leaks and with no disrespect to anyone that does not agree there is a product called engine restore, comes in 4,6,8cyl size, this stuff really does work on worn ring engines by filling cyl scratches with something(possibly graphite).. There is nothing like a proper fix though.

The glycol in the Brake fluid would damage the bearings so much that it wouldn't matter what happened to the seals.

BTW, when you put the sealer in, since that seal is higher than the oil level, you need to drive it or at least start it enough times that the sealer gets splashed onto it frequently.

It was very common for the 5.0's to push oil past the rear main when the pcv system plugged up.A new screen,pcv valve,and a new rubber grommet will fix the problem.Most neglected maintenance item ever on a 5.0 v-8.

Have used Lucas oil treatment with good results. Read the label and see if it will work for you. I have heard of using brake fluid but in transmissions and a long time ago.

IMO...Lucas is the best at softening and swelling seals..

If a seal is cracked.. nothing will help

Maybe back when alcohol was used as brake fluid before the days of DOT 3
