Sludge problem in oil pan
We have a 1998 Grand Prix with a 3100 in it the last person who had it blew the intake gasket; which didn't look like it was installed properly, anyway there is thick sludge (antifreeze and oil) in the oil pan and we have been trying to figure out how to clean it out without removing the pan which would mean pulling the motor. Does anyone have any suggestions?
