oil in throttle body on 96 windstar

My 96` Windstar has a long crank time before starting. I noticed oil in throttle body. Cleaned out and started fine for a day. Now same oil in throttle body, again. Any suggestions? Please reply. Thanks

Try changing pcv valve, allso check for vacuum leakes, You didnt say how many miles, moter jest getten tired?
It wont hart to disassemble throttlel body and clean twice a year or so. Had same problem with a 1990 F150. Make sure you remove idle speed motor and clean behind it.

[SIZE=1][FONT=courier new][COLOR=blue] Try checking your air filter. Mine was clogged up and it would suck oil into the throttle body through the pcv valve trying to get air for the engine.:flash:

i found oil in my air filter what does this mean? and how bad is it really???
