Air Filter hose

[J. Huber]

Am I missing a hose clamp on the filter end of the hose? I notice some oily crud on top of canister. If so, do I go MB or any old hose clamp? Also, I have noticed other's hoses much more bunched up. Is that my imagination?

Hello from the BayArea  - -  -

YES  you are missing a hose clamp.  The oily crud is there because it has most likely dripped out of that same clampless connection point.  The breather hose that comes over from the valve cover is routing an oil-misty mixture of crankcase vapor back into the engine.    This is a easy fix!   Larry in Menlo Park

You may want to look at your air filter element as well as putting on the clamp. Mine was quite gummed up with a mixture of dirt and recirculated vapour from the engine. I replaced it with a MB element and the car has much more power now.

Yes, you are missing a clamp at the air cleaner end, but my hose fits so tightly that I'd be surprised if oil vapor would be enough to cause a leak.  

On the 250s and early 280s separate collar was clamped onto the throttle body to provide a warm water coil around the intake.  On the later 280s it was cast in but on the early ones, the collar  substantially shortened the distance between the throttle body and the air cleaner.  It is a royal pain in the rump to put the hose on these models so be glad yours isn't "bunched up"

Before my engine was rebuilt, there was always an accumulation of oil sitting in the bottom of the air filter canister and in the creases in the connecting hose. Since the rebuild, the canister and hose seem to stay dry/clean - so the oil in your case may be attributable to a worn engine as well. After all, the oil that leaked out of the hose on your car has nowhere else to go but the bottom of the canister once you put the requisite clamp in place, and it will not do much good there  :evil: !
