What is a valve seat insert?

Valve Seat Inserts transfer heat from the valve to cylinder head, mate with the valve to seal combustion pressure, and provide durable wear behavior of both valve and insert, among other crucial functions. Engine design is crucial to your engine's performance and efficiency.

What is PTFE seals for valves?

What do you check on valve springs?

Valve springs have 2 important pressure specs, seat pressure and open pressure. ... If the spring pressures are too high, the added friction will result in:

More heat,
Faster valvetrain wear,
Potential failure of other valvetrain parts (i.e. rocker arms, pushrods, etc.), and.
Less horsepower.

Which check is commonly performed on valve springs?

Always check for clearance between the retainer and the inside face of the rocker arm. This will be most evident while the valve is on the seat. Rocker arms are designed to clear specific spring diameters, so you should check to see that you have the proper rocker arm/retainer combination.
