Why is oil coming out of my dipstick tube?

Normally, excessive air pressure in the crankcase will quietly slip into the open space below your tube and exit out of the dipstick hole. However, overfilling the oil sump can submerge an otherwise non-submerged tube, sealing it and forcing oil to crawl upward in order to relieve pressure.

What causes alot of Blowby?

Typically, blow-by is cylinder pressure leaking past the piston rings into the crankcase. Commonly, it starts as cylinder glazing or carbon forming in the top ring grooves, both of which allow cylinder leak down, and some oil burning. Oil burning produces further ring deposits, and more blow-by.

Why is oil blowing out of the dip stick?

So if the oil dip stick is not secure the pressure of the oil in the engine (when the engine is running of course), will force the oil out of any low pressure area, in this case the dip stick tube. If all else fails, check the bottom of intake manifold for a hole burned through it. I had a oil blowing 350 and that was my problem.

How does a Harley Davidson bypass breather work?

Excess combustion blow-by and oil mist are pushed out of the breathers and exit into your air cleaner, where it is sucked back into the motor to be burned. This system lessens emissions, but can make a mess especially with open element air cleaners, which don’t deliver as much vacuum at the breather to suck up the vapors.

What should I do if my engine oil keeps blowing into the air filter?

Purchase an engine flush formula from your local parts store and follow the directions. In general you will pour the formula into the oil and run the engine for a period of time. Once the engine has been flushed drain the oil and fill it with fresh engine oil. Replace the filter and see if the problem persists.
