- Stops Leaks
- Stops Smoking
- Repair Valve Stem Seal Leaks
- Stop Blue Exhaust Smoke
- Reduce Oil Consumption
The simple answer is:
A seal that fits around the valve stem and valve guide to prevent oil leakage.
The more detailed answer is:
A valve guide seal, also known as a valve stem seal or valve seal, is located on the engine cylinder head inside of the valve springs. An automotive engine can have as few as 8 valves seals, or up to 32. These are located on the intake and exhaust valves and have a pretty difficult job, as they need to allow some oil to pass (so that the valve stem and guide receive lubrication), but need to prevent larger amounts of oil from entering into the combustion chamber to be burned. When too much oil is burned the vehicle will consume oil, emit blue exhaust smoke and cause valve carbon build up. This is bad for the environment, and also the emission system on the vehicle.
Depending on the severity of the leak the first thing you may notice is the engine oil level decreasing. There may be bluish (blue and/or gray) smoke coming from the tailpipe upon starting the vehicle, more noticeably after it has been sitting a while, like overnight.
The most common cause of valve seal leaks is age and/or high kilometres. The seal can also leak due to the vehicle being stored for an extended period of time. Extended storage in particular causes drying and hardening of the seal which leads to shrinking and cracking, and consequently leaking.
A few things can cause a valve seal to leak that is not the fault of the seal itself. The number one factor would be clogged oil drain back returns in the head. These are passages that allow the oil that has been pumped under pressure to the cylinder head for lubrication, to be returned by gravity back into the oil pan. If these passages become partially clogged, oil will fill under the valve cover, actually submerging or flooding the valve seals in oil, and they were not designed to work this way. The usual solution for this is removing the valve cover(s) and running a wire down the return holes to clean them out. This is labor-intensive and expensive.
This product works in two ways to help solve most any valve seal type leak.
1) A specially-engineered seal restorer additive restores valve seal size, flexibility and elasticity lost due to engine heat, age and high kilometres.
2) An advanced seal polymer works by building a polymeric film around the valve seal to help prevent excess oil from bypassing the seal during normal engine operation.
Because of the Rislone multi-action formula, the solution has a custom additive package to work on any type of valve seals, no matter the type or material.

In most cases the valve seal issue will be repaired with a single dosage. But for best results and to prevent the problems from reoccurring, use with every other oil change.
No. Rislone Valve Seal has no particles to plug the leak. Instead, its technology relies on special polymers and seal conditioners to stop valve seal leaks permanently.
Have you noticed that your car is consuming oil? It might be leaking oil, or even burning it in small amounts that you can’t detect. There’s no need to worry or spend your money on a costly repair bill, however. Our Rislone Professional Valve Seal Oil Consumption Repair quickly and safely restores valve seals so you can get back on the road and back to your life.
The most common cause of valve seal leaks is age and/or high mileage. The seal can also leak due to the vehicle being stored for an extended period of time. Extended storage in particular causes drying and hardening of the seal which leads to shrinking and cracking, and consequently leaking. Use Rislone Valve Seal Oil Consumption Repair to reverse aging damage and stop oil consumption dead in its tracks. Not to mention, it works with ALL gasoline and diesel engines using conventional, high mileage and synthetic oil.
