when you pull the timing cover look under your tensioners. Pull that plug out and put it in the back of the head. Now your tensioner will work as advertised.

I had the same problem when I did my PI swap, although I didn't know they could be reversed. I ended up plugging the hole with another plug. Hmm, makes me think.

Now are there plugs for both heads? Or just for the drivers side head?

Can I just leave the Allen plug on the passenger side front and install a new Allen plug on the driver side rear. Leaving the plugs in on the front going to cause oiling issues for the timing system? Really didn’t want to pull the timing cover.
