hey guys i want to start off by thanking you for all the advice i have read on this site i was able to rebuild my top end with the article by eric gorr and tips from posts.i installed a new piston rings rad valves and a complete top end gasket kit.i put it all together and it fired on the second kick,but i have 1 problem.i filled it with oil and after my ride i noticed that the oil level was barely visible in the window.i filled it back up ran it for a while and again the level was back at the bottom of the window.i noticed black goo comming out of the exhaust and thats when i realized i forgot to make sure i had the marks on my rings facing up.does it sound like that is the problem?i want to make sure before i tear it all down again.thanks again for all your help
