hey, i have a '94 jeep grand cherokee laredo, and this is the second time we've had trouble with oil in the air filter. the first time we thought it was because the oil was overfull, but we fixed that problem, and here we are again. we replaced the PCV valve not too long ago... any idea on what the problem could be?

Make sure both front and rear hoses are replaced, otherwise the problem will still continue.
