Last week I noticed big oil leak under car (never leaked before). There was oil sitting up on the intake manifold as well. I retightened valve covers, filled with oil and it doesn't seem to leak up top...having a hard time see where leaking is coming from.

There is a NEW tapping sound...checked lifters and they seem tight. Any easy way to check to see if it's in a rod somewhere?

Here's video so you can hear it:https://youtu.be/35-uWjpaKYY

any ideas appreciated....hate to break it down to much as it's pretty newly built.


I did tighten the lifters on the tapping cylinder and was able to quieten it but didn't want to tighten to much and possibly hurt things more. Noticed that one lifter is not oiling very well...whereas the others are. Could that help inform what's going on?
