Why do crankshaft have drilled oil passages?
This ensures that the main bearings and subsequently the rod bearings get oiled before any top end oiling takes place. Once the mains are adequately lubricated, additional passages in the crankshaft route oil to the rod bearings where the real combustion pounding takes place.
How does oil get into the crankshaft?
Crankshaft lubrication The rod journal bearings require the same lubrication but they are rotating around the crankshaft at an offset. To get the oil to these bearings, oil passageways run inside the crankshaft – through the main journal, diagonally through the web, and out through holes in the rod journals.
Where does the oil go in a crankcase?
There have been many discussions about crankcase breather oil going into the air intake system, the leaks and problems it brings etc. I am considering installing an oil collector to remove the oil before it goes into the turbo.
Why is oil sludge going into my crankcase?
Several reported that the intake manifold was gunked up with oil sludge and also the tubes from the intercooler had gunk in them. One of the guys posted lots of pics of his repair and the whole intake area was sludged up. That’s why I’m leaning toward installing a catch can.
What does it mean when your crankcase breather is blowing oil?
If your crankcase breather is passing oil, chances are that something’s wrong (Okay, we know something’s wrong, but don’t be too alarmed). Here are some things to look for while you’re searching for the source of the issue:
What does it mean when oil spills from crankcase?
Having a separator/catch can means that maintenance needs to be performed. If not emptied, then it’s a spill. Not all MB owners even know how to open the hood much less manage a catch can. I also think that keeping the seals fresh allows the design to work.
What to do when oil comes out of crankcase?
If you can, disconnect the breather hose and push it into a tall bottle with a narrow throat, such as a coke PET bottle and run the engine for about 10 minutes. If you see oil being blown in, check the engine oil level , following the instructions in the owner’s manual for your bike.

What causes oil to leak from a crankcase through an air?
Typically you will get an excess of oil being blown out through the crankcase breather too as the cylinder head/rocker cover is pressurised blowing back down to the crankcase. Best way of checking is to do a compression test on the cylinders.
