I have a problem with an awful lifter / valve train noise at idle and low rpm. At higher >2000 you donít hear it. First we adjust the rockers with a small lash and later with zero lash. Rhoads says that the Vmax needs a certain lash and no preload. Nothing helps and the engine is still noisy especially when its warm up. It is not a silent ticking from lifter it seems that the whole valve train is noisy. I am a bit scary to give preload on the Vmax lifters because it is against the spec from Rhoads.
During my analysis through different forums I discover that some others have similar problems.
Is there any solution or is the Vmax design from the Rhoads lifter the source of the noise ? The Vmax lifter have a high oil bleed and the valve are not hydraulic compressed as they close and touch the cylinderhead. Only at high RPM there is enough oilpressure to keep the oil a bit longer in the lifter.
For any help i say thank you !
