It is normal for a small amount of oil (usually a smokey vapor) to pass from the crankcase breather into the air filter. However, if your having an excessive amount of oil then the the stem seals on the valves have hardened and it is allowing oil to pass along the valve stem through the valve guide through the breather and into the air filter. The remedy is to replace the stem seals under the valve springs inside the cylinder head.

One other thing that will do it is if someone overfilled the engine crankcase with oil. This will cause massive amounts of oil to be pumped into the air filter.

Thanks for using FixYa.

Why is oil leaking from air cleaner?

this is usually due to an oil overfill situation. You most likely added the full quart of oil into the crankcase on setting it up without checking the actual oil level periodically as you fill it. Recheck and drain out the excess as needed.

Why oil is leaking from air cleaner 1999 chevy venture?

Hi
The engine produce little oil steam when is at normal temperature, this is normal.
This steam goes to the air cleaner for recycling.
Now, the reasons to see oil dripping from the air cleaner are:
Engine oil overfilled, or engine breather valve( if fitted) faulty, or the piston rings causing the pressure to scape into the oil sump ( this means engine damage).
get a technician to chem it.
good luck.

Oil pressure low when temp.up

Hi it sounds like you have either worn piston rings /dirty air cleaner /the wrong grade oil in engine as if your temp goes up to high above normal and you have a 10w 40, then change to 30 w 50 and change the oil filter and thermostat,as your sump is also your gear box and you have a gear box heating up the oil just standing still, so do this first and let me know. as piston rings and valve guides are a big and costly job.

I get engine oil to come from the air filter when I tilt the washer more than 90 degrees, this happened while removing the pump unit itself, other wise it works fine, is this normal? should I be worried?

You shouldn't ever tip an engine towards it air filter, when you get oil in the filter, it is usually accompanied with other problems. At least make sure the air filter is cleaned or replaced. I also recommend you remove and clean the carburetor with carb cleaner from your local parts store.

Oil in air filter wot causes this car in qustion is a jag xj8

This issue is caused by crankcase pressure issue.
Normally filtered air enters the engine, runs through the crank case and then is pulled into the intake through the PCV valve. Durning hard acceleration, the PCV valve closes (to prevent explosion of fumes in crank case and blowing valve covers and pan off) and the PCV system reverses, with fumes coming back through the filtered intake.

Usually there is minimal oil that gets back into the air cleaner.

So, when somthing goes wrong, like excessive blow by, for example, the crankcase pressure overcomes the PCV valve and intake of fumes capability, and oily starts showing up in the air filter.

Investigate the crankcase pressure and PCV system.

My barracuda g3 barely goes around the pool and also keeps stopping completly I have taken it to my pool store but they coldn't find anything wrong ith it.

If a store has check the actual pool cleaner for damage and couldn't find any, it is either going to be the connection or the water flow through the cleaner that is causing the lack of motion. Make sure that all of your hoses and connections are tight and secure with no cracks. Air getting into any of the lines could cause problems. You will also want to use your water flow gauge to make sure that you are getting enough water pressure to power the cleaner.

Oil come out the air cleaner

Too much crankcase pressure or the breather pipe is split/dosconnected. The crankcase breather goes into the rear of the air filter and the crankcase gasses are drawn in to the cylinder with the gas/air mixture and burned
