99 Chevy Malibu 2.4 engine. I check my air mass sensor and it was covered with oil and I see that I had oil in the combustion chamber. How to get out oil


Oil is coming from pcv or breather pipe. You probably have excessive piston ring wear causing blowby and forcing combustion gasses up the engine and into the breather and pcv system. Oil will come with the gasses if not filtered out. Check the pcv valve for proper operation and check any breather cap for baffles to keep the oil in the valve covers. Also consider getting an engine rebuild, if you want to keep the car.

Oil keeps getting into the breather changed pc valve hoses and filters


check sump oil level--excessive oil level will cause this
have a compression test done on the engine (both wet and dry) to determine engine condition---excessive blow by from worn rings , bore or cracked piston will cause this --- clean/ replace air filter as if there is a low pressure area after the filter , it helps suck oil vapor from the sump

Ford truck xlt ranger2.3 litter oil in throttle body ? good or bad


I found out with my old 94 Ranger 2.3L that the oil breather does not have a filter element, which causes oil to "naturally" (as Ford puts it) accumulate in the throttle body and air intake hose. You can get an inline breather element at any parts store for a few bucks and install it on the breather line without harming anything, and this will stop. Cheers.

Oil in air filter


No this is not normal, could be what is called the breather pipe, depending on type of car. It is sometimes a pipe that comes from the rocker box into the air filter, becoming blocked or slightly compressed,

Air pressure coming from oil filler neck


Could be any one of a number of problems but first i would check the engine breather which will be a tube from the rocker cover to the air intake as in this tube could be a gauze wire filter and this might need cleaning but iam not familar with this engine so i honestly couldnt tell you where to look for the breather or even what it looks like on this engine which iam assuming is a indian built engine .

Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

if heave oil deposits are coming trough the breather then you may have other problems, such as worn piston rings causing exsessive blow by resulting in the oil being in the intake box, a filter will only create a restriction coursing more poblems, do a compresion and cylinder leak down test to find out how well the rings are sealing.
