engine noise

I know a lot of these posts have been made, but I have to try. I had a shop do $4,000 of work to my 2004 Jeep TJ and when I got it back it started making a high pitch hum or whistle when I am at freeway speed. The sound is like a dull whistle. It goes away if I let go of the gas, and always...

Just purchased this 02 4.0 auto as a project I plan to keep for a long time - relatively new to jeeps and my own maintenance so pardon my frequent questions. I am getting to know the jeep and I’ve noticed a ticking tapping noise on startup that seems to be similar to what others describe as...

Hey guys, I’ve been trying to chase this noise my engine makes ever since I bought the jeep. The noise is a tick/rattle that comes from the engine whenever I lug the engine a little (1600-1900 rpms) or I start from a stop on an incline. Basically whenever the engine is under stress but this...

Just bought an amazing 06 with 89k miles only thing is ... Occasionally when i hold the gas at about ~50 mph i can feel from the seats and console a hmmm...hmmmm...hmm. It’s a repeating “vm” / “hm” sound sounds like from the engine. Any insight?

Yesterday I was driving back down to Jersey after I spent thanksgiving with my family. While I was there, I also took the jeep to get emissions tested (required in CT until the vehicles 25 years old... my '99 is almost exempt...) but it ended up failing due to an evap leak and an o2 sensor. I...

Hey everyone so this thread I posted here is a little preamble to this (https://wranglertjforum.com/threads/new-jeep-owner-and-boy-do-i-need-help-%F0%9F%98%85.37975/#post-630937) thread, but in short I’m a new TJ owner and I’ve been having a number of issues and one of them is random noises. So...

View the attached file and see if anyone can determine what they think the knock may be. I have not heard it up close, only on the video. We just purchased it and want to get opinions. I think I know what it is but let’s see.

This is my 2000 Jeep Wrangler SE 2.5L with 150k miles. Check engine light is not lit and no codes. Oil pressure seems fine and she seems to drive fine. Recently had the exhaust manifold gasket replaced, which solved a lot of noise. I have a light but fast ticking sound at startup, and after...

I have a new noise that started just the other day. I have a video where you can hear it: The rhythmic ticking you hear throughout the video is what I'm talking about. I could not locate it's origin. Sound like anything anyone has heard?

Greetings. I'm looking for some assistance on a new sound. I replaced the lifters about 500 miles ago. I'm not sure if that is related or not to the new sound, but thought I'd mention it. On cold start, it's a loud tapping most noteable underneath the engine. The sound goes away after...
