1998 Chevrolet S10 Q&A

1998 Chevrolet S10 Question: knocking sound coming from oil pan or this general area.

How do i trouble shoot to find out what is making knocking sound. -
Answer 1
knocking noises are rarely good, best possible problem would be a bad knock sensor, next step check to see if your have oil pressure, if no oil pressure then you most likely have a bad rod bearing you would the remove the oil pan and gently tap on bearings to confirm one is loose -
Answer 2
Have a MECHANIC listen to it!! What ever engine it is! 2.2? 4.3? Seasoned tech. can tell you what it is and prob. what you dont want to hear. It's not a sensor. -
Comment 1
Agree with wetry- this is not knock sensor. Don't drive vehicle- qualified mechanic will know what is once started! -
