2000 Avalon I just received my sludge warranty notice from Toyota and got to thinking about this issue. Other than pulling the valve cover, is there any way to determine if an engine has sludge? My Avalon was a lease vehicle. The oil looked fine when I bought it in 2003 and I change it (Valvolene 5/30) every 3 to 5K miles. Thanks. jor
