Products - Tri-Seal – 16 oz.

I have 2 cars 1 is an 1989 and 1 is a 1990 model both with with a Ford 5.0 liter engine. The 90 model was leaking a quart and then some every week. I had tried 2 other different brands of engine stop leaks on the market and the leaks never slowed down. I put a bottle of this Hapco product in and checked my oil the next day as I have to do it everyday due to it enormous oil leakage. I could not detect any oil loss on the dipstick. I put newspapers down under the car overnight and had 2 small patches the size of the bottom of a coffee mug. So I added half of the other bottle ( I bought 2) because I was going to use 1 on the 1989 model car which has been in storage many years. I put down new newspapers, next morning I had no oil spot whatsoever. I drive this car daily and so far the dipstick hasn't moved from full mark all week. Friend if it can stop my cars leak which was gushing like an oil well, I believe if it can stop my cars leaks, you ought to give it a try. As soon as I submit this review I am going to purchase another bottle.

The media could not be loaded. We not use yet but i think will fix us problem in the car.

I did just as the instructions said to and I have now waited for a number of days to give the product a chance to work yet my leak(s) just seem to be getting worse and I’m losing even more oil even quicker than I was previously.. a total waste of time and money!! I see where on the description it says it works every time but I can’t find anywhere that there is an actual guarantee or I would request my money back seeing as how it did not help my situation with the leaks in my engine what do ever!!!

I put haveco Tricia in a 1993 Dodge pickup truck power steering unit and I was adding power steering fluid to it everyday after I put the hapco tri-seal in I ran it for 3 years without ever leaking again

Didn't stop my leak for the price

The product works. I used it to help old seals on transmission and power steering line to seal properly.

Was able to fill on top of my leaking manual transmission within maybe 5 miles could feel it break into smooth flow also added to engine that didn’t need it and waiting on results of anything is better compression all in all buy this if you can’t get time or money for seals will get you going .

Awesome
