Hello Betty. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Please give me one moment to type out some information for you. Sit tight one minute. I'll be right back !

Okay thank you
Automotive Expert
Thank you for holding Betty, Needing a tune-up on your 2008 Avenger is not going to cause the engine to knock so having one done is not likely going to solve the engine knock. The first thing you need to do here is to have the oil level and condition checked to be sure it's properly filled and the oil is clean. If it's low and overdue for an oil change then that would be the place to start here. If the knock remains after having the oil service done, then unfortunately this is most likely an internal engine concern such as a knocking piston rod and or even a possible collapsed lifter. When you take it in for the oil service be sure to have your mechanic have a listen to the knock and they can usually give you a good idea of the actual source.

Wow Ron that's what I was thinking I am thankful for your help I'm going to take her ( my car) in now for the oil change and go from there'sThere
Automotive Expert
Okay, don't put this off any longer than you just have to Betty so you can avoid any further damage.

Okay I'm going today if not I'm not going to drive her until I get an oil change
Automotive Expert
Very good idea for sure. Hopefully, the oil change will get the car back to normal for you.
Automotive Expert
Thank you Betty! Glad I could be of some help today! I hope everything works out well for you! If there are any additional questions on this issue that should arise, please feel free to reply and ask! Have a great day.

I found out there is to much oil in my engine but I can’t find a place open I’m still trying do you think that can cause knocking
Automotive Expert
It's not likely having it over full will cause the knocking your describing. The best thing to do here is to correct the oil level and let's see if that helps.
