I just got a call from my mechanic... I took in my rodeo to get the t-belt changed, and it turns out it is not bad. He sais something about an "oil flow back valve?" does that make sense? he said that they are plugged, and not getting enough oil in. he said i may want to try a detergent in it.... any ideas? im gonna change oil and stuff this weekend so its a good time.... I have 120k on it.
