Hi all, I was attempting to diagnose a high idle upon ignition, and discovered that a silver hose connected to the base of my air filter hub had broken in place. I should probably replace, but I can’t figure out what this hose is called, or what better part to replace with. The other end seemingly snakes under the engine and looks very tricky to access! Please help!

1989 Jeep Comanche 4.0L Straight 6 / Manual Transmission / 4 wheel drive Build date: 1/89 Current Location: Tallahassee, FL Status: Daily driver Notes: Red exterior, grey interior, bench seats, vinyl seats and floor, floor shift. Just rolled over 100,000 miles and recently had the engine rebuilt. Current owner: Nick Gilpin

Shop called today, ended up being a clutch bearing! They will drop the transmission and fix at no charge. Thank you all! I’ll report back on if it’s fixed next week!

I just called the shop that replaced the catalytic converter/muffler and they say it’s all good and tight down there. Taking it in to the shop that did the engine work tomorrow morning for a look.

Thank you all for the replies. I’ve uploaded a sound clip of the noise to help anyone assess. This is in neutral, pressing the accelerator with the microphone held near the shifter. Comanche Noise.m4a

Hi all, first post here. I’ve owned a 1989 Comanche, manual straight 6 cylinder 4.0, since December 2018 and have done a significant amount of repairs. Regarding this specific question: I’ve recently had the engine rebuilt, the clutch, master, and slave all replaced, and a new exhaust and catalytic converter installed (as recently as today). Last week, I noticed a low rattle when starting the truck, that eventually goes away and comes back intermittently. Additionally, I’ve noticed a loud grinding rattle/clanking at higher RPMs (can’t say what RPM due to not having a tachometer). I have googled for days, and paid north of $7K for the above repairs, and related repairs, such as new spark plugs, hoses, etc. I am running out of patience (and money!). Please help!
