Check sump oil level
other reason is excessive blow by from worn rings , turning the oil to vapor which is being sucked to the air inlet
have a wet and dry compression test done to determine engine condition

Just replaced air filter, fuel filter, and plug. Ran good for 10 minutes then started spuddering and died. Restarted right away and huge cloud of blue smoke came out. It spudders for a minute and dies


Blue smoke is oil. Have you checked you pcv? (Pollution control valve) it usually runs from one of the valve covers to the airfilter unit.

Your PCV valve is usually about a $2 part and is suppose to keep oil out of this tube. Follow the tube back to the valve cover and the PCV valve should be there.

Excessive blow by could also cause oil to get into this tube. The blow by is usually caused by worn piston rings or valve guides. The compressed air/fuel mixture or exhaust pushes past these areas and make it into the crank case. Usually if you have a lot of blow by, you'll see your dipstick tube popped out a bit too.

PCV valve is cheap and easy to change... I'd give it a try.

Oil in the air filter and housing


Normally due to a worn out engine, called "blow by."
But, see if you have an air tube coming from the valve cover that may have a PCV (positive crankcase ventilation) valve. This valve can plug up and cause a little bit of oil issue.
You can get a compression test done to see what condition the engine is in.

Shooting oil out of dipstick


Your engine breather system is blocked....this means that the only way that the compression caused on ignition that is getting past the piston rings and into the block can escape is via the dipstick tube.
Check breather for kinks and some have filters ensure that these are not blocked

Oil is coming out of my air filter on my 1986 cabriolet vw


How many miles are on it? Check and clean the crank case ventilation (from the top of the valve cover to the air filter box) if there is a pcv valve check it and you may have to clean it. If not you have blow by some of the compress is going around the pistons into the motor and blow the oil out.

Oil in the air filter


Well this this will be you valve cover gaskets leaking. Try to feel around or look to see if there is fresh oil around the valve cover. Oil being sucked in to the air filter is a sure sign of a leak in your engine compartment. Check your oil levels also. Hope this helped.

1999 Nissan Sentra oil in air filter


First off, nothing "blows" into the air filter. It would be getting sucked in from somewhere in your engine compartment. My guess would be leaking valve cover. Check around and feel for wet oil. That will also be a leak. Have you been going through more oil than usual? Check that also. Hope that helped.
