Can't find how to attach pics.
So my issue is the vct. Pretty sure it's the culprit. Does the knocking at idle once warmed up. Non existent at 1200rpm. Sometimes it'll make the noise at one stop light but not the next. Haven't done a compression test. Bogs a tiny bit coming to a stop (atmospheric bov).Also fuel pressure doesn't hold once primed. Other than that, the cars runs great. Pulls hard. Af ratios are good and so is vac (sits at 19). Any suggestions would be greatly appreciated.

You might want to refine your mod list to things that are germane to your issue. I don't think east bear mirrors have anything to do with an engine knock/tap.

I'd suggest doing a compression check, and oil pressure check.

I said, "I wanted to post my car.". Also, I thought I posted to the "I'm new and I have a simple question" thread.
