How concerned should I be? On vacation.

[jkaput]

Hi again.

How concerned should I be about this noise? I’m on vacation again. And I’m zero for around eight for a stress free wife experience when it comes to this van and our vacations.

I’m hoping I can just deal with it later?

Well, man, you got a few problems.

1. Your motor mounts are shot
2. Your exhaust is leaking
3. Your O2 sensor is non operational and needs to be replaced

But your engine doesn't leak oil and you've got new axles, so that's nice. I don't even know what sound you're referring to. The grumbly brbrbrbrbr (which is probably an exhaust leak) or the high pitched eee eee eee (which is probably your motor mounts.)

Probably ignore it. Unless anyone has a keener ear and can discern any problems.

As long as your vacationing at Smith College, you're fine.

Exhaust leak not too serious.

Rough running - cap rotor plugs wires.

Get that wiring cleaned up - look at that wire sawing itself on that sheet metal!

Yeah, I'm with 4gears.

It's not clear what sound you're referring to. With your O2 sensor wire being severed in two I'm guessing your mpg is pretty bad.

Where are you on Vacation? There might be one of us nearby that could assist.

Right at the end of the clip, center of frame, it looks like your header is broken in half. That could explain the noise.

[SCM]

That might be his O2 sensor wire dangling down in front of the header making it look like a crack. Hard to tell.

Another video, this one with the view looking DOWN on the engine from the top, with the cover REMOVED, would help all of us. This way we can see how much movement your engine mounts are allowing, if the Altn. is wobbling a bunch.
Won't change what appears to be an exhaust leak, but adds info for the Samba Hive Mind to help you.

Sorry everyone. Cell service is rough in the White Mtns.

Cut the O2 bc it stumbles when it’s connected and runs really rough. Not sure why but I’m not going to puzzle that out here.

The clack clack sound like metal on metal. Intermittent. It seems to go away under load but that could just be the increase in frequency making it hard hear.

It’s definitely increased on this trip. I’ll make another video when I get all the shit out of the back (it’s jammed to the gills).

The exhaust is new btw but I was wondering if there was a leak myself.

As long as it makes it back to mass (smith college area to be exact!!) I’m fine. It can blow up at home all it wants. My wife will lose it if we have another vacation van fiasco.

Me too maybe.

The one noise sounds like an exhaust leak. With the exhaust cold, crawl underneath and be ready to quickly feel for leaks once the wife starts the engine, you have maybe 30 seconds to safely do this before the exhaust is hot enough to burn you.

What to be concerned about? Well you dont appear to have any oil leak, suggesting you have run out of oil.

With the O2 sensor not plugged in, your ECU will provide a basic map without the fine adjustments the sensor provides. It may well be that the exhaust leak was screwing up the mix making it run badly because the sensor was seeing too much oxygen... If the exhaust does leak, your mpgs will likely be better with it unplugged - obviously the best is with a tight exhaust and a fresh, plugged in sensor.

The clanking sound reminds me of a water pump at the end of it's life - hard to tell, given the recording quality (microphone placement) and the symphony of sounds...

With engine off and preferably cold, inspect the water pump for any sign of weaping or leaks, and try moving the pulley axially (in and out) or otherwise check for looseness or wobbling - there should be no noticeable movement except radialy (rotation).

Water pumps generally don't fail catastrophically, they usually get progressively louder and weap or leak a little more as the mileage piles up. I've done over over a thousand miles on a failing water pump. It's loud and embarrassing, mostly for the wife.

While you have the engine cold, shake the exhaust pipes and see if you can replicate the sound to track it down.

Auto or manual? My buddy's auto transmission had a cracked flex plate that sounded a bit like that.

Keep us posted on how you make out. Always an adventure, isn't it...

is that silver anti seize on the base of the O2 bung?

Seems like all systems normal, if your fix is cutting the O2 sensor wire, why didn't you just dis connect it?

If your wife does hear the exhaust leak and she's fine as long as you're rolling then you're goo to go.

I'd wager that to disconnect it would have required access to the top of the engine (tin) and the rear hatch is full of camping and living gear.

it's a tad extreme but ... it happens
