If you're experiencing engine issues that *seem* like they might be valve related (noise, poor performance), the problem likely lies elsewhere. It could be something like:
* Worn lifters: While you can't adjust them, they can wear out and need replacement.
* Low oil level or incorrect oil viscosity: This is a common cause of valve train noise.
* Other engine problems: The noise might be coming from a different part of the engine entirely.
Trying to adjust valves on a hydraulic lifter engine will do nothing but waste time and potentially damage the engine. If you're having engine problems, take it to a qualified mechanic for diagnosis and repair.
