I've noticed that the squeal disappears when my oil is slightly overfilled. If the dipstick level shows about 1/8 of an inch above the full line, (~4 to 8 ounces) - my 89 200T is quiet. Why would that be? BTDT's? Is the engine at risk because of the extra oil? Scott Spangenberg scotts@utm.net 89 200T 182K MI 85 5ks - gone 79 5ks - gone
