Title: Front Engine Cover Oil ??
Post by: Lucky_Lou on February 10, 2010, 11:43:45 AM

Ive started getting Gertie ready for the big ride next month to Wootton Bassett, i decided to tart her up a bit by fitting some stainless steel bolts to the engine cover.The road salt has taken its toll, when i pulled the old bolts out the bottom two (of 3)on the right looking from the front came out oily?.
 Any ideas what to expect when i pull it off to investigate (next week hopefully) ill be pulling it off to check the points anyway.
 I dont recall this being there when i did the rebuild just over 1000 miles ago

The o-ring on the ignition 'bean can', or the front main seal, would be my first and second guesses .

Possibility of a leak around one of the timing cover bolts, loose bolt, or gasket gone bad .

The O-ring (seal on some models) on the bean can would be my guess also.

Hope its nice and simple like the Bean can spigot O ring. It's also possible for oil to get inside the bean can through the drive shaft mechanical seal and then drip out of the front cover.

There is a 28x47x7 oil seal in the Timing case Cover for the crankshaft ball bearing. Getting to it is a real PITA. I would expect a larger amount of oil with a seal failure. Hope it the bean can O-ring...   Monte
