I cannot find the leak, but there is pooling of oil in some of the boss holes near the valve cover gaskets. I have torqued most all the bolts on the valve covers; those I can get too wiithout taking parts off the engine. The oil is still leaking. I suspect valve cover o-ring seals, but maybe you know of something else, like maybe 0-ring seals on the fuel injectors. I cannot determine if any injector is leaking oil without taking off parts or pieces. Any other source where oil can seep and run down the side of the motor would be helpful. The oil fill cap is not leaking.
Is there a PVC valve that requires service, where internal engine pressure is blowing oil out some seals? If so I cannot locate it.
The car runs fine and adding oil between changes at 2000 miles is not necessary, but the engine block is "wet" with oil and when parked in the garage, drips oil onto the floor. Any help would be appreciated.
PS: A 3.8 Liter Buick, 2001 is doing the same. Help if you can. Thanks, Larry
have the same problem?
