A breather in oil systems is essential for maintaining proper pressure and allowing for the expansion and contraction of oil as temperatures change. It prevents vacuum formation, which can hinder oil flow and lead to potential damage. Additionally, it helps to vent any accumulated gases, maintaining optimal system performance and longevity. Overall, a breather ensures the oil reservoir remains functional and efficient.
In my 1993 Ford F-150, I had oil in the breather due to a blown head gasket.

The oil might be getting into the air breather of your 2000 S10 pickup if there is a leaky gasket on the engine. It could also indicate the air breather housing is cracked.
Oil coming out of the air breather on a Harley can indicate a few issues, often related to excessive crankcase pressure or improper engine breathing. This can be caused by worn piston rings, valve guides, or a clogged breather system. Additionally, if the bike is overfilled with oil, it can lead to oil being forced out of the air breather. Regular maintenance and checks can help prevent this issue.
Engine oil coming from breather pipe
Check your oil, if it looks the same you may have a blown head gasket. If your oil looks okay you may just have had some water get in it from somewhere else. I found that i had milky residue in my breather and the problem ended up being the carb was forcing air back down the breather tube. When air is forced into a small space it compresses and moisturises. The solution was to take off the breather tube and put a cap or separate breather filter on it.
Engine is severely worn.
Breather pluged.
Check oil level on dipstick, oil could be over serviced.
If you have a 1.8T, the breather for the crankcase is below the intake manifold. The poor design of the engine causes oil to be sucked up through the breather and sit in the breather assembly then causing it to rot and fail. When you aredriving slow, the vapors from your crankcase waft in through the cabin air intake. you need to purchase a breather T fitting, it is expensive -about 45 dollars from the dealer, and install it. Look below the intake on the drivers side of the engine for the faulty part.
There will be a removable cap, or breather on the valve cover.
the crankcase vents through the breather system.
