Ok Here is my problem. I have a 94 T-bird 4.6 80500 miles. It just started consuming oil. This oil change I don't even have 3000 miles and I have used 3qt's of oil. :redmad: So I replaced my PCV valve, Checked #1 sparkplug to see if there was ash on it. (Talking to the guy at a the dealer ship said to look for ash on it) I don't ever see any blue smoke out the exhaust, no drips on the pavement. I also didn't notice any decrease in gas mileage. All seems fine. Just I am haveing my oil dissapere. Any Ideas on where it could be going, What to look for. If I was burning it what are some of the signs? I was told to try a leak down test? I thought that was to check for proper sealing of the rings. I don't know. I know it is the nature of these engiens to burn some oil. My 04 stang dose but it is 1/2 qt every 3k miles. Thanks for any help.
