More random pics from Ouray.
If you met McGuire, then you probably met @cruisermatt !!
Crazy that the guy rolled Goss. I'm sure he'll fix it up though. Pics look killer Mike.

I've known McGuire for years and his dad Jimmy. I did meet cruiserMatt, he's a great guy. He shattered his bell housing but replaced it at camp then went on to the Rubicon like it was nothing. Wish you had made it out Johnny.

Ok diesel gurus, need advice. While towing the trailer uphill in Colorado, i was cut off where i lost momentum and had to pull over. When i pulled over, temps hit nearly 270 for a few minutes before dropping back down.
The rig did ok for the rest of the trip considering the elevation. On the way back to Texas, I noticed i can't get boost past 20psi and it would smoke a lot.
Now i assume its just a boost leak, but could that temp spike have caused any other damage?
I just took this pic after trying to get it to go passed 20psi. Couldn't do it without smoking out the town.
Give me your thoughts.

The black buildup on the exhaust wrap could be an indication of an exhaust leak. I’d unwrap it and check it out. The V-band on the turbo looks black with soot also.

Yea, definitely have an exhaust leak. After I posted up, i turned it on and revved the engine, you can see it coming out the gaskets. I'm just hoping that's all that is.
My guess is your lacking enough air to help burn the fuel. Could be that you need a bigger air inlet or you have a leak somewhere. Does your air filter have any signs of collapsing in on itself?

Just replaced the air filter on the way back with another K&N of the same model. No sign of collapse, was just really gunked up.
I can't see any places where there could be leaks but I'll check more as i get caught up on work.

270 is HOT. Check your oil and coolant levels. Change your oil soon.
EDIT: Thinking about it more, 270* while shut down is different than 270* while running. Heat soak can cause coolant jacket temps to peek into the "overheating" range without a real problem present. This is where electric fans come in handy, as you can manually run them after the engine is off to help cool it down quicker.
What did your EGTs do during this event?
Sounds like you developed an exhaust leak that prevented boost from building, and the overfueling condition that then existed caused your engine to overheat.

Troubleshooting ideas and baseline checks:
With that temp I'd be checking the oil for signs of coolant and the coolant for signs of oil. Look at the coolant level, how about oil level? Are you consuming more than normal? Do you recall what your egts where at when the temp spiked?
For low boost that crossover pipe leak will definitely reduce spool up and boost levels from your big turbo so your small turbo looks like it's doing all the work. Out of curiousity I'd pull off the inlets and spin the turbos by hand (engine cold of course) to make sure they are spinning as you expect. If one doesn't spin it's not producing boost and is a restriction in the exhaust path. That will mean internal issues with the turbo and would probably need a rebuild or replacement. Also mean low power and smokey-ness.
If all that checks out you have a know issue with the crossover pipe. I'd address that. If that doesn't fix it then it's tracing down all the intake. All boots, clamp tightness, intercooler for cracks/leaks, intake plate gasket, boost reference lines, etc. For me, when I have noticable boost leaks the turbo spool sounds different. Instead of a "Hisssss" kind of sound it's more like a "shhhhhh" kind of sound.
My experience with these engines is that they are stupid strong, take ridiculous abuse, and will pull their guts out if you ask them to. They are not indestructible but put up with a lot as long as we maintain them.

No oil in the coolant, can't see coolant in the oil. Coolant doesn't bubble, so thinking a good head gasket still. EGTs were near 1200 when this happened. Very rarely did i go above that and only for a few seconds. The turbos spool well, no play, but will check again later today after my meetings are done.
I did notice some oil consumption while going uphill with the trailer, but some of that loss is leaks from the engine. Will be changing the oil soon, but I will say I am consuming a bit more than normal and a lot of it is from the crank case vent.
I noticed the temp wire was exposed and pretty much sitting on the exhaust manifold. Hoping that gives me a hotter or false reading.

Hopefully this helps with the heat and noise.
Also who doesn't enjoy a vw R type hatch with custom paint as an overlanding rig.

Looks like the insulation helped with the noise and heat reduction.
I'm packing up to hit the Ozarks with the Tacoma. Managed to fit everything i need without the trailer.
Getting too old to keep mounting the rtt by myself.
All my recovery gear fit in the black box. Repurposing some military issue for the trails. Bought a heavy duty chainsaw, hopefully i use it at least once.
Don't need the trailer for this trip.

Big Red just passed state inspection
. I wasn't too worried about it, but the shop I usually go to has an entirely new staff, so you never know how anal they were going to be. I usually drive it and do the brake checks and so on while they watch. This new kid insisted it has to be him, so I let him get in. He couldn't figure out how to turn it on (the starter switch is not by the key) and he couldn't drive a manual transmission. So he got out and checked my headlights and brake lights, then passed me. Didn't even look for the signal lights.
I remember a time when you weren't considered a man unless you can do basic things like drive a stick. But I guess that's just my toxic masculinity getting the best of me. When I get back from the Ozarks I will tackle the exhaust leaks and lack of boost issues.

Time for another update. Aurora has been wanting to do an Ozarks trip for some time and so we went over Labor Day weekend. I used the opportunity to buy a heavy duty gas chainsaw and to my surprise, she was all about it. I'm glad we did as we had to cut some trails when we got lost and eventually temporarily stuck when we slid in the mud. Arkansas had been hit by the remnants of Hurricane Laura and was raining all the way during our drive. So plenty of mud, skeeters and flowing water. We had just returned from Colorado not too long ago and needed to get some maintenance on Big Red, plus we wanted AC on this trip, so we took her Tacoma. I just want to say, you haven't lived unless you've wheeled with the AC on.
She had planned the trip, downloaded the trails and pretty much packed the entire truck and fridge. When there was high water, she walked it without complaint. Best copilot I've ever had. We took hours of video and tons of pics. We lost some footage, but still have plenty. I'll eventually get around to uploading them.
Everything fit in the back, so there was no need for a trailer. I used some of my military boxes to carry smaller items that I don't want getting wet. The chain saw had it's water proof hard case and the generator was wrapped in a garbage bag.
I was tired from driving so she set up camp and made dinner.
The next day we hiked a bit to a water fall and swam. This was just one of several water falls and by no means representative of the beauty and height of some of them.
One of our first deep-ish water crossings. That spring water was freezing, at least that"s what she said.
By the end of the day, we ended up on a trail that wasn't used in a ling time. At one point the tacoma slid and we were stuck over this fallen tree. Luckily, I had that chain saw with me. It took maybe 20 minutes of cutting and doing a 30 point turn, but we eventually got back on the right track.
I'll post more pics tomorrow and continue telling the story.

The second day was equally fun. We drove to a bunch of trailsheads, hiked some and wheeled the others. In between trails we managed to stop by an automobile museum, we were not disappointed.
we eventually went thru that river.
We were surprised how many old cemeteries were located on the trails. It seems like no one lived nearby for tens of miles. Many of the gravestones were from the 1800s.
