What can happen if a valve is never adjusted?

What can happen if they never get adjusted – valve clearance is set because metal expands when it gets hot. If the clearance is too tight, the valve won’t seat fully in the head. This can cause loss of compression, or even destroy the valve by overheating because the head acts like a heat sink to dissipate the heat from the valve.

When do you switch to an adjustable valvetrain?

If we switch to solid lifters it is mandatory that we convert to an adjustable valvetrain (I would also say that converting to adjustable valvetrain is mandatory in ALL racing applications as well as any application where we want to have accurate control of our valve lash setting). Not doing so is asking for serious problems!

How do you adjust the valves on a car?

A threaded rod or an eccentric at the end of each rocker arm adjusts the clearance to the top of the valve. You rotate the engine until that cylinder’s piston is at the top of its stroke—a.k.a. top dead center—and each of its valves are fully closed, the springs uncompressed, the system at its loosest.

What should I do if my Nissan truck has a vacuum leak?

Often it’s as simple as tracking down a vacuum leak, which is far cheaper than replacing your car’s engine control unit (ECU). This question came from a reader who owns a 1997 Nissan pickup truck. The small engine in this truck is similar to many other engines in Nissans and other makes.
