So I pulled my plugs last night, and thought I’d give the rings a bit of lubrication with marvel mystery oil. I put about 1 oz down each cylinder and let it sit overnight.
I turned the engine a bit this morning, and then hooked up my gauge on #1A. It’s going off the charts! Within 3 cranks, it’s already at 300 psi. Either my gauge is busted, or can too much oil still sitting in cylinder do this? I thought it would have seeped thru by now.
