Spark knock, How to get rid of it? on 2010 Jeep Wrangler

3.8 motor, manual trans.Did more in hot weather. BUT still happens when motor is running temp. I have 33,000 miles. It is definitely Spark knock or motor ping. I have read a lot about it however would like to hear from this site. Only pings when accelerating. Help me please?

Pull your air breather hose off and you will see oil all in you air intake . If you take off your pcv valve and cap the air Intake side and then flush the carbon from your pistons with water and then it will not come back . But don't hook the pcv valve back up

Needs to be hooked to a scanner to monitor data-fuel trim , CTS , O2s ,etc. Poss. running lean or faulty knock sensor. Could be lots of things, diagnose may be cheaper than guessing.
Thank you. I have an Actron scanner that will show live perameters. Do you know of any numbers to go by? OR what I need to look for on the fuel trim? Will the KNOCK sensor throw a code out? ... I do not have any lights on , on the dash. Thanks CM
Have someone else drive it and watch the spark advance and knock sensor activity. Before you get to far into it.......2010 and 33,000 miles- Check your warranty book(s)- may be covered under warranty Federal emissions warranty on some items goes past the standard manufacturers powertrain warranty of 3/36..............back to the other stuff--LTFT should be close to 1.00 +/- .03 check coolant temp.-should be between 210 & 220F fully warmed up.Any aftermarket mods?
No mods yet. All stock. Bought Jeep used w/ 23000miles. Thanks for the info I will check it out.
