My fathers 94 GC 4.0 keeps getting oil into the air filter box and then also runs into the carb. He tried running a hose with a T on it with one going to the filter box and the other into a jar to collect oil, but he is still getting a ton of oil into the AF housing. Anyone here have any ideas on what he can do? Thanks in advance

 

replace the CCV system.. the back metering valve(in valve cover) is probably clogged. Parts are dealer only but pretty cheap.

You can try to clean it but you will most likely break it taking it out.

 

Thank you very much Seed
