Does anyone else's 20V engines consume around a quart of oil every 1500 miles or thereabouts? Changing the oil last night, I also noticed spent oil around the bottom of the oil pan near the oil plug. These plugs are the larger ones (not like the 4KQ's). Is there suppose to be a seal or washer on the plug (mine doesn't have any)? Dan Cooke cooke@cs.lmco.com '90 90Q20V '86 4KCSQ
