![]() ![]() Note how the second ring is worn only on the bottom half – which is where this oil control ring should wear. In WOT dyno testing, likely the rings are seated by the end of the first few runs. With today’s rings, especially moly-faced versions, this can be achieved in a very short period of time and certainly within 20 to 30 miles of street driving. The cylinder pressure from 50 to 75 percent and eventually to 100 percent load will place additional pressure on the back side of the rings which will quickly establish the proper wear pattern for seating. You want to keep the rpm above 1,500 and vary the speed continuously for about the first 20 minutes.” After bringing the engine up to normalized coolant and oil temperature, put the engine under load. According to JE’s Senior Technical Account Manager Alan Stevenson, “You don’t want to break-in an engine at idle. As soon as the engine starts, immediately bring it up to an above-idle speed. For carbureted engines, this means pre-filling the fuel bowls and accurately setting the initial timing. The ideal combination is to tune the engine so that it starts on the first or second revolution. This brings us to how the engine should be run after initial startup. This places a premium on proper honing technique and finish. Cylinder wall taper or out-of-round makes the ring’s task of sealing and break-in much more difficult. Highly viscous or sticky engine assembly lubes should be avoided around the ring package. This lubricant will be present only for the initial revolutions until the engine starts. When assembling the engine, JE recommends using either engine oil or a light machine oil for the cylinder wall and rings. Lubrication is another critical element in this process but oil can only achieve its intended goals of lubrication and improving ring seal when the other conditions are also met. Creating the proper height of these peaks and the depth of the valleys will significantly improve the potential for ring seal. In order to do this, the rings will remove the microscopic peaks created by the honing process. The somewhat rough surface of a freshly-honed cylinder is established in part to promote a wear pattern between it and the ring face. That included angle helps both retain oil and also promotes ring movement within the grooves, which is important to maintain sealing. It’s beyond the focus of this story to get into specific procedures, but a proper torque plate honing with a 45 degree included honing angle is certainly moving in the right direction. Idealizing ring seal starts with proper cylinder honing. As we’ll see, the process is somewhat specific and less than rewarding if you screw it up! Bore finish will have a lasting effect on both how well the rings break in and the extent that they seal both cylinder pressure and keep oil out of the chamber. This goes way beyond just choosing the right break-in oil, although that’s an excellent start. More power! One way to ensure the horsepower built into your engine is achieved is to seize every opportunity to seal that cylinder pressure on the push side of the pistons.Ī great way to take full advantage of the 21st Century engineering that goes into piston rings is optimize the break-in / ring seating procedure. AMSOIL Shock Therapy Synthetic Suspension Fluids are recommended for front forks and shocks on snowmobiles, motocross and cruiser motorcycles, ATVs and other racing and recreational use vehicles, as well as cars and trucks that require their suspension systems to perform in the most extreme conditions.Captain Kirk in the now-classic Star Trek TV series was constantly badgering poor Scotty for “More power!” That’s what everybody wants. AMSOIL Shock Therapy Synthetic Suspension Fluid contains friction modifiers to reduce the energy loss caused by friction, while antiwear agents are added to protect shocks and forks from premature wear. The base stocks of AMSOIL Shock Therapy Synthetic Suspension Fluids have inherently high viscosity indices that effectively maintain their viscosities, while their antifoam agents reduce aeration and foam therefore, they make suspension systems more predictable. The complete additive package reduces foaming, aeration and wear, while seal conditioners are added to keep seals soft and pliable. AMSOIL Shock Therapy Synthetic Suspension Fluids are formulated with shear stable synthetic base stocks with high viscosity indices.
