Review on Bar'S Leaks MS-1 Main Seal Motor Oil Leak Repair, 32 Fl. Oz by Djuan Thompson

Sealed my daughters literally empty crankcase. We put this in along with 4 quarts oil. Not an oil change it was simply running on oil film I thinkShe drove 2000 miles to Chicago and back and we then put 2 mote quarts in to fill up oil after she got back. Shop wants 2500.00 to fix. So maybe we will put this in every 3000 miles til she can get another car. Keeps u going a while longer at least
