My dad's '05 L33 is consuming a lot of oil; 1.5 qts in 1500 miles with 70,000 on the odo. I have read that a poorly designed valve cover is the issue here. Is this an issue that can be fixed as a recall? If not, what are the options? This problem seems to be getting worse with both his L33's. Any help wold be appreciated. Feel free to PM with details.
