    Valve cover issue with oil cap

    Hi
    I would like any suggestions on valve covers I have the stock one on but last week heard a loud pop while W.O.T. Got home took look and noticed that my nuc oil bypass cap came loose and doesn’t tighten down any more and there was oil over the valve cover so I found my stock cap and it seems to tighten down to where it clicks but I haven’t seen if it leaks oil cause I haven’t plugged the oil bypass yet, I’m also running a compound turbo setup so my question is do I eventually have to upgrade to billet valve cover? And has there been any issues with the nuc oil bypass cap? Cause I noticed the threads on the cap are not as thick as the stock cap so I was thinking of ordering a insane diesel oil pass threw cap cause the threads look like the stock cap to use on the stock valve cover until I get billet one your thoughts on what I should do? Thanks for your time

    I have the NUC set up and have no issues.
    My friend made his own set up and went to NAPA, bought a swivel 90 for his stock cap, drilled and installed it with no issues.
    Both set ups are fine.

    My oil bypass cap came with a kit but didn’t like the way it fit the valve cover. I upgraded to this one, expensive but it’s very well made and fits great. No problems in almost a year.
