confused 98 Windstar;Engine oil in air cleaner tube

hello,

i have a 98 windstar. I noticed i have engine oil in the tube that goes from the throttle body to the air cleaner box. Does anyone know what would cause this? The van idles and runs fine.

thanks for any information on this problem that i have.

Make sure the intake is tight and secure. Next, check the filter if you haven't done so and replace if necessary. If it is clean and the intake is secure, then I'd suggest cleaning the throttle body. Remove the unit and all applicable sensors. If the TB is oily, then you've found your culprit. Spray the TB with TB cleaner, wipe with a clean dry rag and then reinstall. Take photos if necessary or if you don't have a repair manual.

Perhaps others will chime in with other suggestions on what it could be.

Hi
I dont think you have a problem. Every car is oily in that section, but i dont know how oily is yours. But remember DO NOT CLEAN THE TROTTLE BODY NEVER. Trotle body is coated with special coat to reduce air resistance so the mass air flow gives more accurate readings. Your problem is the air filter and you must check condition of pcv valve. If the valve is stucked for a minute and then release , it can give a shoots of oil and this is bad.
Good luck

I've removed and cleaned the TB on my '99 Taurus with NO problems. You'd be surprised how dirty it can get after 10 years.

It's safe to clean the TB with TB cleaner.
