I've never had a problem w/ my car's oil level, it has almost 28k on it, I did the balance shaft removal, and added the oil when i was done. I added 1 extra qt and it was still lower, so I added more. Later that day I was wayyyyy over. So i took some out. It was perfectly in the middle. I drove for a while no problems. Last week I started it up and my valves were chattering so i added a little oil, and the chatter went away. This morning I start her up and the valves are chatting again. I turned it off and checked the oil and it was a little less than half on the stick between Low and High. I had no extra oil at the house so I drove to work. I'm going to get more oil but want to know what's the deal w/ the valves chattering and the oil level fluctiating(sp)?
