Engine pinging/spark knock outlander 2003 4G69 2.4 L
#11
The headgasket was just replaced. And the head was machined because it was slightly warped. After the repair it drove fine for a day and then started pinging. And has gotten really bad. I've changed knock sensor and MAF. Strange thing though is the knocking stops when I disconnect the MAF. It sounds like the computer is advancing the timing too much but I can't figure out why. I did get a trouble code P0075.(Oil control valve). But cleared it and it hasn't returned.

I think that your headgasket is blown again. The problem on my engine whas that the headgasket was not tightened enough (compressed) from factory. Take out one cyl head bolt and check the end of the threads if its damaged. On my engine the threads on the top deck was too shallow so the headbolts hitting the bottom of the threads and didnt compress the headgasket.
I hope that im wrong.

no its not the lifters ticking.... as i said before, im a pretty good mechanic and i have been in a top door slammer/pro mod team and also built 3 racing engines so im pretty sure its not the lifters. now im off to the garage to check if the cranktrigger is ****ed up...
more ideas please.

I had it diagnosed and all it is, is your transmission. Purchase the gear box from wreckers for under $600 aud. Although I will say when you replace it with the new one, you need to use all of the old gear cogs and diff, the mouse simple comes from the axle or whatever you would call it ( the rod that the gears are on. Not sure exactly how it works but this is the reason your car is knocking.
it was getting on my nerves for over 2 years and I was stressing every day and night and trying to figure out solutions. Hope this helps 12+ years later.
