Oil Seal Engine Oil Burning & Leak Repair

  • Repairs Leaking Main Seals and Gaskets
  • Renews Worn Valve Seals and Guides
  • Stops Oil Burning & Blue Exhaust Smoke

Product Details:

Can a single product handle both oil leaks and excessive oil burning? Yes it can.

This product fixes both problems. There could be two possible reasons as to why your vehicle is burning engine oil. It may have an oil leak or you it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So, when the fuel ignites the oil does as well, and then expels it out as exhaust. Then, suddenly, you’re dealing with an oil burning problem.

The good news is that with a single application of Rislone Oil Seal, those problems will be gone.
