Why is oil pumping into air cleaner on your 88 fxrp?In: Motorcycles |
[Edit] |
Answer
It's probably caused by "blow-by". Blow-by is caused when the pressurized exhaust leaks past the pistons, into the crankcase. The moving gasses pick up oil vapor. The exhaust gas dumps into the air cleaner and if the engine has blow-by the exhaust gas the oil will deposit in the air cleaner.
So to make it short, blow-by means the engine is worn, it's not a good thing.
