Just looking for suggestions on this engine noise. This is from cold start. This is fully warmed up. This noise has me fully baffled. The truck has always been a little noisy. Just looking for thoughts of what I might be missing. Backstory: The truck has always been a little noisy. Sometimes the noise will almost go completely away. Sometimes it sounds like something is trying to escape. With a mechanics stethoscope you can hear a tick everywhere on the engine. Head all the way to the oil pan but nowhere is any louder than the rest. Noise is still there without a belt. Oil pressure is at 50+ psi cold and drops to 25psi completely warmed up at idle. Goes back up to 50+ when driving. Ran marvel mystery oil 1000 miles and just put in fresh Rotella 15/40 with a wix filter. Any thoughts would be greatly appreciated.

Hi All, This is my first ever post on this forum or any forum for that matter. I have an 87 Comanche 4.0 pioneer that has a bad ticking noise. It has been doing this noise for the last 6 months I've owned the truck. I've run thicker weight oils, various additives and they did little to help. The noise is strange in that it is intermittent and only seems to get bad after the engine is fully warm. Did the rear main seal two months ago and didn't notice any metal debris in pan. It doesn't get noticably audible until oil pressure is under 40. Seems to be worse at idle(or just easier to hear) or when coming to a red light after driving at higher speeds. I have had two people listen to it and one believed it was most likely a bad lifter. The other seemed to think it was a possible exhaust issue. I believe that I do have some exhaust leak, but I don't think it could be the cause of metalic click noise. I am leaning toward it being the lifters, but I also know these engines can develop piston slap. Before I get into any fixes is there anything that can be done to help determine if the tick is a lifter, piston, or possible exhaust? What do you guys think it sounds like? I have attached a short clip of the engine ticking when fully warm. Thanks for any advice you may have. VID_20190522_091052028~3.mp4

My inner shifter boot is completely falling apart. I need to adjust the cutout for the shifter a bit anyways (Peugeot to AX-15 swap problem). Is there another application boot that works nicely and can be sourced? Something generic even? Maybe something a little larger since I'm going to have to hog the hole out a little?

MJ Model: 1989 Jeep MJ 4.0L 2WD Issue at hand: At lower speeds when turning, I notice a vibration coming from the front driver side wheel. Seems to be worse when turning and I can kinda feel it driving straight. What I have done: I have installed a 2" lift using coil spacers and chevy drop shackles. I did not get an adjustable track bar. This was done about 6 months ago. I then had a weird noise and vibration in the same tire so I thought it was my bearings. I replaced the bearings with new ones. The issue was still there so I thought it was because I didnt replace the one piece rotor at the same time. So, I replaced the rotor and with new bearings again. (I packed the bearings very well)... Seemed to help but issue was still there. When the truck is parked, and when I grab the top of the tire and shake it back and forth, I hear a clicking like something is loose. So I replaced my ball joints. Problem still there. Brake pads looked good and didnt have unusual wear. Would appreciate some insight.

When my 1988 Comanche reaches 57.5 MPH a vibration and noise comes from underneath. It vibrates my seat. At 70 MPH it runs smoothe with no noise or vibration. This is something that does not happen all the time. BTW there is NO steering wheel movement. ANY suggestions would be appreciated. My first Comanche so I am clueless.

Please help me with this terrible noise...:/ 1992 comanche 4.0 5-speed, 80k miles....pretty much stock and taken care of... View My Video

I want to decrease road noise. Has anyone tried using styrofoam packing peanuts in the cab corners all the way up the B-pillar? I know spray foam is a major no no.
