| Gave the bike a once over today and noticed this oil leak where the right side intake joins the airbox. First thought was that it's due to the previous owner's mechanic over-filling the oil. But the clear overflow hose is completely dry, as is the left side junction. Any ideas? [You must be registered and logged in to see this image.] | |

| Pull your air cleaner, guaranteed there is oil residue in the bottom of your air box.
Don't stress, its just part of the Guzzi life. |

| What Wyne said The reason your don't see oil in the drain tube is because the drain hole is located at the center-rear of the airbox which is a little higher than the seam. When I just got the bike, I filled the engine oil to the three quater point on the dipstick and after 10,000km I found oil stain on the airbox seam and also a little engine oil pooling in the airbox. Airbox inspection cover under the battery [You must be registered and logged in to see this image.]The bike is on side stand [You must be registered and logged in to see this image.]This is the drain hole where the drain tube connected to, by the time you see oil in the drain tube it will be a small swimming pool in the airbox [You must be registered and logged in to see this image.]Right hand side "velocity stack", right below it is the seam where the oil seep out and appear on the outer side [You must be registered and logged in to see this image.]I have adjusted the engine oil volume to 1/4 on the dipstick and no more oil stain on the airbox seam since then.

| Well at least you got oil. It's not like old British cars, one that doesn't leak is one with no oil in the engine. Then there's Lucas, the Prince of Darkness... | |

| No problem guys. While we are on the subject, here's some GRiSO porn [You must be registered and logged in to see this image.]The two clear drain tubes are connected to the ----- (what is the proper term for this?) circled in red Yellow circle connected to the blow-by system's "gut" I like the air box design and the way it is integrated to the GRiSO very much, isn't it a beauty? | |

| Read that somebody took out the rubber inlet pipe to the air box to make a bit of room for tools and such just behind it. Obviouslu without obstructing the opening would that affect the air flow into the filter box much and therefore affect combustion? | |

| Yep. Too much oil in the sump. I find about 3.3 litres is right for mine (despite the book saying 3.6 litres). Others will have different values - Why? It's Guzzi, each one is unique. Take a little form the sump, after checking where it is on the dip stick - it should be "about" half way between high and low marks. | |

| Having recently cleaned out the long neglected lower area of the airbox cos I had the same oil weep at the seam. I was thinking about the oil that had got into the TB's and how to squirt carb cleaner in there without having to go in behind the battery. Suggestions ? | |

| Pull it all apart and give it a good clean. If it's worth doing it's worth doing properly. The throttle body assembly can be disconnected from the throttle cables and the whole assembly removed for cleaning. Once done, it will make a difference, providing you don't touch the alignment in any way - apart from syncing the throttle bodies when you re-install them. Don't forget to flush your stepper motor while you're at it. | |

| Hello, Ive got this oil leak in the joint of TB with the head, should I replace the gasket?. I've got also humidity, in both seams of the tube and the airbox. What should be done? [You must be registered and logged in to see this image.] | |

| The oil weep at the airbox join with the inlet is due to excessive oil in the airbox, probably due to the sump being over filled. Drain and clean the airbox and don't run your oil any higher than half way between the 'Add' and 'Full' marks on the stick. Then replace the inlet manifold gasket and see if it stops weeping. | |
