Rislone Head Gasket Fix is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. 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 might include taking the engine apart to clean all of the parts.

“Looks ok! Works in my engine. I'm using this for a couple of days now seems solve the my problem no air pressure to the radiator and the overheating is gone I will continue to monitor will see what it goes. 2005 Honda Civic SI.”
“I have a 2008 Dodge Grand Caravan 3.3L engine and was adding coolant every week. Adding 4 litres antifreeze approx. per week. Used a bottle of Rislone gasket seal and instantly solved problem!”
“Used this product on my 2008 uplander & son's 2006 Chev Optra. We followed the instructions - drained and filled the cooling system - added the head gasket fix by Rislone. Worked like a charm. Highly recommend
Rislone Head Gasket Fix. Has been about a year and a half. GREAT STUFF!!!!!!!!!”
“Had a small leak at the rear of the head, decided to add Rislone and sealed it in less then five minutes, this was done four months ago and no leaks.The only thing the instructions don't say is you have to remove a bit more of the coolant from the radiator than the amount of the bottle. I truly stand behind this product.”
“It's working, my car was having the head gasket blown as my engine oil was found milky and the gases from exhaust pipe was white and watery. My car was vibrating violently as well, all these was happened after I did a radiator flush.
The day after I found this product online, and have it a try. It amazingly work and simple! My car is getting back to normal now and no more vibration and white gas from the exhaust! Cool product that save ppl a lot of money! Recommended!”
“Amazing! Love this stuff! It works - stopped my head gasket leak and still going after 100,000 km.”
“I was loosing 2 litres of water a day from a head gasket. A real bad leak. A no-hoper. Used 3/4 of a bottle in a car with a 10.5 quart US cooling system capacity. The car is still blowing water out the overflow tank, but it is very much reduced. I will insert the remaining 1/4 bottle if it does not settle down completely. I am amazed at how well it did work. Made the car drivable again. The technology has really improved over the years. If that does not work completely, I will try Rislone's product for 'bigger leaks' .... the stuff in the smaller bottle. Thanks Rislone.”
“No more water coming out the reservoir bottle. Repair has been good for a week now.
So I went from leaking 2 liters of coolant a day, to a complete stop of leaking coolant.
I purchased a bottle of Rislone engine block sealer for larger leaks, and carry it around just in case. Thanks Rislone for making my car drivable again. This is a good product. I will drain my coolant system and will add some anti freeze soon. The heater core is still heating the interior of the car, and has not plugged up.”
