The pcv valve is probably on the valve cover.If the engine is blowing oil out of the crankcase or the oil filler tube,it could be the pcv valve.It could also be an indication of internal wear,such as stucking valves,causing the engine to build up excessive pressure.

How does a radial engine differ from a normal engine?

The "normal" engine is also called a rotary engine. Both of these engines look very similar. Radial engines use a conventional crankshaft in a fixed engine block, unlike the rotary engine. +++ You've missed the fundamental point. A conventional engine has its cylinders in a straight line or lines. A radial engine's cylinders are arranged, as its name says, radially from the polygonal crankcase, like the spokes of a wheel.

What causes gas in the oil on a 350 engine?

If it runs fairly normal once it starts and you're getting fuel into the crankcase, it's PROBABLY a leaking injector. After the engine is shut off there is still pressure in the fuel line. If the injector leaks, fuel will drip down into the intake manifold. If a cylinder has an open intake valve, the fuel will leak into there and find it's way into the crankcase.

Changed oil and filter on my 06 Camry V6 and no oil dripped from filter Is this normal?

It is likely that the crankcase was much too oil. It is likely that the engine would have been damaged if the oil had not be changed.

Why does 2 cycle engine run-on?

2-stroke engines run on a gas-oil mixture put directly into the gas tank. They do not have a crankcase that holds oil separately like most normal 4-stroke engines.

What makes a 1984 ford ranger pump oil into the air filter?

There's a valve called the PCV (positive crankcase ventilation) valve that allows air build-up inside the engine to vent out of the block (crankcase). It is designed to allow air to pass but keep the oil inside the engine.They are a normal wear item and your manual probably says to replace it every year. I do mine automatically when I do tuneups - it takes less than 5 minutes and you can do it yourself.

1992 yz250 has gas in the crankcase what's wrong?

Worse case scenario. Float needle stuck in the carb with piston on the intake stroke. Rings may have washed out allowing fuel to pass into the crankcase. You didn't state how much gas though. Your yz uses the oil in the gas to lubricate the crankcase so a little is normal.

Oil in air box ninja 250?

There's a hose that runs from the top of the engine/transmission to the airbox. This is the Crankcase vent hose. Pressure in the crankcase caused by blowby is relieved into the airbox to reduce pollution. It's 100% normal for there to by oil in the bottom of the airbox Running the engine for long periods of time above 8,000RPM will increase the amount of oil in the airbox. There's a little drain hose on the bottom of the airbox, just pull the plug and let the oil drain out into the pan everytime you do an oil change.

Why is oil coming out around dip stick on 4cyl 1995 jeep yj and what would fix the problem?

If it is coming out around the top of the stick, you have either a plugged pcv valve/crankcase orifice tube or excessive engine blow by. Blow by is the normal leakage past the piston rings. Excessive blow by will require a new/rebuilt engine.
