Excessive oil from the breather tube (between valve cover and air filter box)?

This was passed from the late Dr. Marshall Booth on an email list I subscribe to:

If it has been fixed, you'll see a gray epoxy covered area. If it needs fixing, you'll see about an eighth inch gap. Clean the area with brake-clean and apply epoxy.

Don't use RTV. Don't use J-B Weld (it takes too long to dry and will ooze through the gap. The official stuff was Lock-tite/NAPA 5-minute epoxy. It does an excellent job and is oil resistant. We used to do this at the M-B dealer in the 1980s. It paid an additional 2 tenths of an hour to do the job with a valve adjustment.

Make sure that you have the revised flat one piece hose that connects the valve cover vent to the air cleaner and not the 3 piece original one. It's inexpensive - maybe $12 last time I checked.
