I was Trained to do this test the same way.

The Cardboard and the Math.

Your about 18% difference.

Put some Marvel Mystery oil in #2 or maybe all of them.

Let it sit.
Maybe a day or two.

Crank it over (Without the plugs in.

Then crank it up out in the wide open Spaces.


Let it burn off the oil.

Then do another Check.

A leak down check will tell the real deal.

I think the Mystery oil will be the (Sandpaper ) cure to keep you Putting down the road.

I did a leak down test while I was testing compression and I had no noticeable drop. I'm ok with what I found and have driven it four or five times to town with no issues.
