Replaced pcv valve because oil getting in air cleaner but that didn't fix the problem what else could be wrong?

Make sure PCV valve has good vacuum. Valve cover or covers depending if 6 cyl. or 8 cyl. have to be able to flow air in from air cleaner to valve cover thru engine and sucked back up by PCV system. It is possible that the engine just has to much blow by the engine rings.

Oil in airfilter and in airbox

Usually a sign of blow-by which is when the oil is getting past the rings or valve seals. You could have a problem with the PCV system too.
The PCV valve draws crankcase fumes into the intake and fresh air into the engine from the air cleaner.
If it is blow-by there's not much you can do about it short of rebuilding or replacing the engine.

pcv blockage pcv positive crankcase valve maybe a collapsed hose in your pcv system

Oil shoot out through air filter

That means your engine already have big blowback, air from engine crankshaft goes out into the engine oil cover and into the pcv valve to the air cleaner.
It is cause by the compression leakage from piston rings.
Better check and clean the PCV first or buy a new one if it is fully blocked. Located from the engine oil cover, follow the hose on top, hose goes into PCV and into air cleaner.

Hope that helps you out!

Codes P0506 and P0011. Idles low and rough. What can I do?

P0011 A Camshaft Position - Timing Over - Advanced or System Performance (Bank 1) P0506 Idle Air Control System RPM Lower Than Expected A P0506 DTC trouble code may be caused by one or more of the following:
  • A vacuum leak
  • An air restriction in the intake air path or exhuast
  • A faulty positive crankcase ventilation (PCV) valve
  • Damaged/failed/dirty throttle body
  • Internal engine problem
  • Failed PCM
  • check the PCV valve first , thats cheap , just shake it, you should hear the little ball rolling back and forth, if it is,, put it back, if not,, spray a little carb cleaner in it,, then put it back after the ball has loosened up , then start the car ,, spray a little carb cleaner around the vacuum lines of the motor, if the car rev's up all of a sudden, look for a bad vacuum hose in that area , check and clean the air filter, normally this code is thrown by a vehicle that has an electronic throttle control, ( no cable ) remove the air duct that goes into the throttle body , spray some cleaner in there,, ( with the motor off) wipe out any excess , and clean the flap that is inside that hole,, be careful not to spray too much on the tip of the sensor that in there,,, start the car again, if its better your home free, it may smoke a little to clear out the carb spray ,, so don't worry , if that doesn't fix your problem,, your going to have to replace the idle control sensor, lemme know how you make out

Oil in air cleaner and dripping in manifold heat shield,and oil smoke out exaust. changed pcv valve ok for 10 miles then a quart of oil later smoke out. love that car.

It's time to replace the engine. The rings on the pistons have worn out. They are letting oil get in the cylinders thus causing it to smoke. And they are letting the compession of thecylinders blow into the crankcase, this is why you oil in the air cleaner. it's just tired.

Driving down the road at 55 and the car lets out a bunch of white smoke for about 5 seconds then goes away the when i stoped and looking in the air filter base it is full of oil. How can i fix it

you might get lucky with a new PCV valve. But it sounds like you have a small leak in either the intake manifold or a head gasket. if so it will get worse soon. white smoke is water. blue is oil. black is gas. place a white rag or paper towel at the tailpipe to get the true color of the smoke

I have oil around my air cleaner housing what can i do ?

I'm assuming you mean inside of your air cleaner you either need to clean air cleaner housing replace air filter and PCV valve and or PCV breather filter hose, PCV system or your engine has excessive blowby and is worn internally.

Where is the pcv valve located on a 2003 ford ranger

  • The PCV valve can be located in several places. The most common location is in a rubber grommet in the valve cover. It can be installed in the middle of the hose connections, as well as installed directly in the intake manifold.
  • Once the PCV valve is located, make sure all the PCV system hoses are properly connected and that they have no breaks or cracks.
  • Remove the air cleaner and inspect the air and crankcase filters. Crankcase blowby can clog these with oil. Clean or replace such filters.
  • Oil in the air cleaner assembly indicates that the PCV valve or hoses are plugged.
  • Make sure you check these and replace the valve and clean the hoses and air cleaner assembly.
  • When the PCV valve and hose are in satisfactory condition and there is oil in the air cleaner assembly, perform a cylinder compression test to check for worn cylinders and piston rings.

    Heavy Smoke

    Yeah,,your engine is showing signs of wear, if it blows a lot of oil out the back end after sitting at a light or stop sign,,then that is a sure indicator of Valve seals needing replacement,,,but it also sounds like your engine is worn out Piston Rings and all.
    You could try a product which is used on just about every drag racing strip,,it's called Lucas Oil treatment,,,i don't promise that it will solve all your problems,,,but if it don't help,,it sure wont hurt.

    Best of luck to ya.
