If you notice oil leaks in the upper part of the engine, do not hesitate to change the rocker cover gasket. It's a simple and inexpensive operation. Your engine will keep all its shine.
There are 2 types of rocker cover gaskets :
• The GUG705009VC gasket fits on the 9-stud cylinder head.
• The GUG5038VC gasket fits on the 11-stud cylinder head.
Double-check which cylinder head is fitted to the Mini before ordering the rocker cover gasket.
• The GUG705009VC gasket fits on the 9-stud cylinder head.
• The GUG5038VC gasket fits on the 11-stud cylinder head.
Double-check which cylinder head is fitted to the Mini before ordering the rocker cover gasket.
The original rocker cover gasket is made of cork. There are also silicone rocker cover gaskets available. The silicone gasket will last longer than the cork gasket if you frequently remove the rocker cover.
