Where do I add liquid to the crankcase in a 1998 Buick Park Avenue, 3.8L, V6 engine?
I think it gets added the same place oil is added... Directions on this bottle of "Oil Treatment" say Add to crankcase
, but I am not sure where the access to add liquid to the crankcase is located.
Please help; I do not want to kill my engine. :? :cry:
