Re: Loss of compression in all cylinders

And... how much oil does it use? I would think bad ring seal across the board would show up as increased oil consumption. I bought one of those cheap USB cameras just for mysteries like this. With one you can peek at pistons and cylinder walls... It doesn't use a lot. It's not like I'm topping it o...

Or I'd have Jones Cams grind a custom. Erson will also grind a custom.
