Products - Tri-Seal (Pack of 2)

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

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!!!

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 .

3 bottles in 16 quarts of oil hasn't stopped the leak in my 7.3 diesel. The recommendation is 2oz per quart of oil. That would be two 16 oz bottles. I'll add one more 16oz bottle to see what happens. I'm pretty sure the leaks are due to using synthetic oil in this engine. I'll update the review if the leaks stop with 0.5 oz per quart.

I think it may be helping but still to early to know for sure.

Do not use this product in your transmission… Its job is to swell up the rubber seals And if they swell up inside your Allison 1000 from your Duramax it will cost you over five grand to fix it….ask me how I know… This cheap garbage cost me $5200 and guess what Amazon did about it…. A big fat nothing
