Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine.

“This stuff is fantastic. My Mercedes was pumping out so much water vapor from my exhaust I first thought my car was on fire with so much smoke. I was also having to fill up the water reservoir often. I receive two quotes for repair of the head gasket $2,000 and $2,500. After following the Rislone instructions it has worked very well for over one and a half years now. I use to live on one of the highest streets in Wellington which is fairly mountainous, so even the extra stress of the steep hill climbs didn't stop the Rislone product from working.”
