The benefit of a leak test is knowing what to look for before tearing the engine apart. Don't be overly concerned about a leak down tester, we already know that it is leaking too much so the amount of leakage is not critical. Where the leak is at is what we want to find out...with no tension on the rockers at all, put air in the cylinder and see where it leaks out from, the tailpipe, intake manifold, cooling system and or the crankcase/oil pan.

Was thinking about whether or not you could pull the head and the lower oil pan only to remove just the number two piston if that is where the problem is at, hone/deglaze re-ring that cylinder and go down the road. It just depends on what you want out of the car. I did the first repair size .5 mm pistons/bore on my 240 and it ran like a dream.

The bouncing gauge is puzzling. Nothing in the cylinder should affect whether or not the gauge holds a reading.
