Ok had vc gaskets done. Had a spare set powder coated and put on. Shortly after driving home from garage, oil light flickers. Throughout the day it would come on at idle. I than noticed later on its a little noisy at start up. I googled an bunch of stuff . I had oil sensor replaced and put in 5w30 synthetic in. Before I did that I unscrewed cap and looked inside. I saw some gritty oil which I know is not good. I don't think they sandblasted the covers when they powdered them but dipped them instead. Only thing I can think is there was some dried oil in the baffles on valve cover. I cleaned them as good as could but thinking it may have got into motor. Oil was not gritty when I draned it though. So far the light hasn't come on and it's not as noisy. I do however see a pan leak now too. Anyone have any input. My guy tried to check pressure but had wrong sized fitting.
