Haven't seen anything abnormal yet. Will keep an eye on it. If it does, then I can go solid. Seem like anything with a camshaft anymore is more bad news than good news.
Well good luck with it. Hydraulic rollers specify a good bit of preload to keep the lifters from "ski jumping" off the ramps and then crashing back down on the lobes. Loose or no preload is terrible on the valve train.
