B40F Oil on wiring in tool box - from oil breather ?
« on: 31 March, 2018, 18:42:35 »
When it was running the wiring around the battery was getting a bit oily. Residue still there . Looking at the back of the oil tank the feed pipe to the rocker looks clean (no pipe clip on it), but the return pipe is oily and suspect ( that does have  pipe clip). I will change the return pipe.

However, oil marks on the wiring seem too high for that  to be the source/only source. I notice what looks like a breather (3/4" long painted pipe spur) near the top of the tank.  Can these/should this spit oil.........and if so is it normal or indicative of problems ?

Also should the rocker feed be fine without pipe clips ? as I have none at both ends

The problem is that you get quick a bit a splashing of the returning oil at the top of the tank and some will find its way out of the breather. It's probably best to run a rubber pipe from the breather to below the engine to protect the wiring.

Too much oil in the tank will usually cause some to be discharged from the tank breather.

The rocker feed end of the pipe shouldn't need a clip provided it is a reasonably tight fit on the copper pipe. However, the oil tank end should have a clip fitted since the metal feed pipe is relatively short and, if the rubber pipe falls off, it could be catastrophic for the engine!
