behsuzgas Valve Saver Fluid forms a protective lubricant coating; the effect of separating the two metals by a film of lubricant prevents metal-to-metal contact stopping Valve Seat Recession.
Not all engines are designed with LPG/CNG as the fuel.
In engines converted to LPG/CNG , there is potential for higher valve wear due to the combustion properties of the fuel.
LPG/CNG as a fuel places significantly higher exhaust thermal stresses on the valves and valve seats, increasing wear.
Valve Seat Recession is where the valve seat sealing face wears into the cylinder head.
An engine on LPG/CNG runs hotter than designed, under extreme heat normal exhaust and inlet valves can lose their hardness and tensile strength.
The situation worsens as the valve face now hotter than designed and without lubrication preventing the metals touching pinpoint weld themselves together.
As the valves open, the welds break. Valves are designed to rotate consequently pitting the entire surface on both the valve and valve seat.
This leaves the valve face pitted, softened and vulnerable to increased wear. The valve face no longer seals, allowing hotter exhaust gases further heat the surface accelerating wear.
The grinding created by the rotational valves, wear away the seat and guides. Resulting in lost compression and power.
