Smoke is blue/white at start up/idle and low speed throttle. Improves over 60C but is still there.
Got in contact with the shop that rebuilt the fuel pump. They are thinking it is either a compression issue or timing was set up wrong. The shop that installed the fuel pump reported good/equal compression across the cylinders and the last oil analysis was fine. But given the quality of work, I'm going to ask a mechanic to check compression and timing while I'm in Europe.

Have you considered moving to a different platform?

Have you considered moving to a different platform?

I 100% have.But I'm committed to this rig. As much as I post about mechanical obstacles, it also delivers in many other ways. To me, it's home.
I've left the Heffalump in CA with a mobile mechanic that has worked on it a couple of times. He is no MB truck expert. But he is honest and will do what he can while I''m away. Also been chatting with the guys at Sure Marine in Seattle. We may gut the current Webasto system in favor of a new unit and also adding a kick board heater to improve winter heating.

Currently in E. Ukraine to support a NGO with medivacs. Looking forward to updates and seeing what can be accomplished while away.

Just came back to the USA and the saga continues.
2 months was spent assisting with medivacs in E. Ukraine. Regardless of how anyone feels about politics. It's very humbling to meet/know people who are fighting for their independence and freedom. Everyday people who were simple civilians prior to the war.
Arrived back in California 2 days ago. There is still some smoke, but greatly improved. Mechanic suspects oil getting through somewhere. Ordered a new webasto system including a hydronic heater, wiring harness, and will be adding a kick board heater with a small fan, and an improved thermostat but it never shipped so I'll pick it up in Seattle. My thought process is to start with a new system that I install and will be better equipped to understand and repair.
Picked up the heffalump and drove 25 miles to pick up my dog Tobi. And... Unfortunately the parking brake is now seized. Tapping the drum with a 4lb hammer did not release it. I can't even move the adjuster wheels. A mechanic is going to come out today to see if he can help. It's on it's 2nd brake canister since I've owned it and the last one was installed this summer. Shoes and drums are also new. Parking brake lever has been changed 3x since I've owned it. I do have a spare wedge actuator on hand that can be swapped in as needed. I also have a brake regulator still that the last mechanic did not install. (attaching pics). For whatever reason, I've been unable to locate this on the truck. In my mind, worse case scenario is that he cages that brake and I get this up to Washington State where I can park it longer and do another deeper drive into system repairs.

The thought of shipping it an expert in Europe is becoming more appealing... Defiantly would not take this to Ukraine though! Hahahaha!
I'd also consider an expert, "one stop shop" in the Americas. I have not experienced quality work/communication with MB trucks experts in California, Colorado, or BC Canada.
