No clue
I have a 90 ranger 2.3 that seems to have a mind of it,s own lately. About a mounth ago it started pouring black smoke out every once in a while, now it seems to be getting worse. I did the normal things like clean Maf, fuel regulator was changed last year,checked for vaccum leaks the whole works. I pulled KOEO codes an got 33,41,66,88,95 any suggestons to what could be the problem .

I'm not a professional mechanic, so this advice is worth what you're paying for it. :-)
A blocked PCV valve will cause increased pressure within the engine and can cause oil to go places you don't want it to.

O = KOEO
R = KOER
C = Continuous Memory
33 (R,C) EGR valve fault/ not closing properly
41 (R) HEGO/HO2S sensor voltage low/system lean
(C) No HO2S switching detected or sensor signal out of range.
66 (O,C) TOT sensor signal input below self-test minimum, or vane air flow circuit below minimum.
88 (O,C) Choke relay out of range or Dual plug input control failure or shift solenoid 3/4-4/3
95 (O,C) fuel pump secondary circuit fail.
