Engine is severely worn.
Not enough info.
That should be the crankcase breather tube.
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.
The oil is probably coming in through the crankcase breather tube and into the air breather assembly. You either have a faulty PCV system or a very tired engine with "blowby".
usually a gastet problem Check the breather tube, you might be getting "blow-by" into the intake.
Remove the crankcase breather cap up in front of the engine and add motor oil down the tube.
Engine over full, diesel in the oil, excessive blowby.
On the top side of engine, underneath breather element tube, under top radiator hose
you put all the gas from the petrol into a tube with water and then a spare tube will take the crude oil into it. so there you go.
High Oil Pressure In an engine usually comes from a clogged crank case breather, or bad oil pump.. best advise is to do a pm and hope for the best
In my 1993 Ford F-150, I had oil in the breather due to a blown head gasket.
there is a breather tube with a large vent cap on top, pull the vent cap off and the tube is exposed, put oil in the tube. It is located on the right side ( sitting in seat ) of engine just forward of distributer ! Terry !
