I had chrome valve covers on mine and had to get some cast aluminum ones. No matter how hard I tried to get the chrome ones to seal good, they wouldn't. I think the previous owner overtorqued them and they were ever so slightly bent at the ends, and they leaked. Doesn't leak now with the cast aluminum covers (about $80). Had another leak show up after replacing the covers. Traced it back to a bad gasket on the oil filter. Also had my fuel pump leaking at the block. When it leaked it blew back everywhere and you couldn't tell where it was coming from. Think I fixed my "last" oil leak after trying to fix all of them for about a year. Frustrating ain't it??? Hope this helps.
