Need help guys, Just started today
Have a 2009 sierra 1500 with 4.8L. Got 198,000 kms. I am original owner and have been loyal to the maintenance of the truck. Yes oil changes every 5000 kms. I am not sure on the noise. It started today. It is there whether the truck is cold or warm. makes more clunking when reving. I posted a video on You tube at the link below of the noise.
Sounds like it is coming from the drivers side towards the back on the piston cover. I used a screw driver to listen to the piston housing and that is where most of the noise is coming from. Also if I crawl underneath the truck I can hear noise to from the bottom of the motor but all the noise does sound up high for sure.
Let me know if you have any suggestions.
Thanks
John
