1400 Touring puking oil...still

[JohninVT]

Title says it all.  Every time I take it on a high speed run on the interstate it pukes oil when I stop.  It’s not over filled.

Could it be coming out of some sort of breather system as it does it under the same conditions every time? Some of these guys here maybe can shed some light. I know it's aggravating:(

The crankcase breather tube on my Norge eventually split because of the heat. Oil everywhere. Solution: Cut the split end off the existing tube and put it back on while waiting for a new breather tube to arrive on the slow boat from Italy.

Despite what MG says in the manual, these engines seek their own ideal oil level...if level is above LOW mark on dipstick, keep riding until puking stops then check dipstick...that is your ideal oil level...

I hate when my bike "goes British"!
But seriously.....
Did this start after a recent repair or oil change?
When you say that it's not overfilled with oil do you mean it's at the full mark? Many late model Guzzi will vent oil if filled above halfway between the marks. Have you been replacing the oil that has been escaping? You may want to monitor the oil level but not add any unless it reaches the minimum and see if the level stabilizes.
Another possibility would be a malfunctioning check valve in the breather.

It’s my fifth Guzzi so I’m aware they pump it out the tube when overfilled.  It’s just touching the bottom mark on the dipstick when then engine is hot, standing upright.  If I ride it over 80mph for any extended period of time it will puddle under the bike.  It’s not coming out the overflow tube.  It looks like it’s dripping from the bottom of the air box.

My 1400 will puke oil until it reads below halfway on the dipstick, after that it stabilises and doesn't use a drop.

Lots of places the hi cam motor can be suspect.  Maybe time to pull the tank and have a look around. Banjo fittings on oil feeds to heads and breather hoses to covers on cam sprockets as well as plug tube seals are a few common spots. The clear drain tube with the rubber plug from the airbox should be the only normal place to see oil purging.

Gain access to the air box and wipe it clean.  Then go for a spirited ride and look again.  It could be carrying oil from previous occasions.

Getting to the air box is not easy.  I've abandoned the side clips, because they broke and were a pain to get back on.

Weird innit? Some bikes are worse than others but as others have said the most likely cause is over-filling, even though the dipstick says it's *Right*.

Drain the airbox. Start with the oil level just below half way between the 'Full' and 'Add' marks and certainly don't add any more unless the level actually drops off the bottom of the stick.

I never had significant expulsion problems on mine but it simply stopped *Using* any once the level got to dead on the 'Add' mark. It got used pretty hard, heavily loaded in very hot conditions.

Just got back from a 1,000+ mile trip.  I had checked the airbox before I left and everything looked fine.  The bike hadn't been leaking and the dipstick read between the lines.  When I got home last night I noticed it was leaking on the garage floor.  A lot.  I looked underneath and there are two lines next to the airbox on the left side.  Both were covered in oil.  I haven't bothered checking to see if one or both are split or if they're just not fastened well enough.  They look like they're miserable to get at and I'm not sure if I have to remove the airbox to inspect them.  I suppose I can be glad there was still oil in the bike since I'd just ridden it 160 miles non-stop on the interstate.

msince this is an on going issue John, I'd probably bite the bullit and tear it down to however far I had to, to get to the issue. It's about to have to be something minor, don't you think?
