if you have oil in the intake, you could have a faulty PCV valve that's allowing oil to weep into the intake. this will dirty up the intake pretty severely and will make mileage drop tremendously.
a PCV is about $3 and takes about 30 seconds to change.
that's a crap load of miles for a thank. so which one is it? the pcv valve i need to change or do a engine swap? I don't want to spend much money. Considering it takes only 30 seconds to do the PCV change, where is it located?
thanks
