Massive oil in air filter 93 cherokee
 

I have a 93 cherokee with a 4.0 HO in it and I am getting a huge
ammount of oil in the air filter. I have replaced the oil cap, the
front elbow/grommet and hose that go from valve cover to the airfilter
and I have replaced the rear metered hole elbow/grommet and vacuum
lines. I am still getting alot of oil into the air filter. I was told
the \PCV valve is built into the valve cover. is that true? I am not
burning any oil and when I change the oil it is clean. I seem to have
good compression but all the oil is causing me to loose power, mileage
etc....

HELP!!!!!!!!!!!!!!!!!!!!!!!!

Re: Massive oil in air filter 93 cherokee
 

There is a known problem with the PCV system and another one caused by a
gummed up throttle body that can also lead to oil in the air filter.

I think the PCV problem was with earlier models but I am sure someone with
the information will chime in with the appropriate dates. The fix there is
replacement of parts.

The throttle body fix entails a thorough cleaning of all the gum, gunk,
goop, and misc crud with an old toothbrush and a spray can of good cleaner
such as GumOut JetSpray. It is easy enough for anyone to do on a warm
summer day (when I did mine) and a bit more troublesome while standing in
the snow.

I have some before and after pix..... for some reason I neglected to take
any once I actually started the cleaning..

Hi Jeremy,
There's an orifice at the base of the throttle butterfly that gets
clogged with carbon, that acts like a Positive Crankcase Venation valve:

Re: Massive oil in air filter 93 cherokee
 

Thanks foor the info, I have removed the valve cover and cleaned out
the snorkles and the such and according to the dealership and JEEP my
cherokee doesnt have a valve cover gasket so I used MOPAR RTV ,
probably the same as any other RTV, but I am going to replace the plugs
and change the oil today while I am waiting the 24 hours forthe rtv to
cure. I am then going to attempt to clean the throttle body really good
and cross my fingers.
