So this weekend I started out by tracking down the leak in the drivers floor area. Looks like many years of old sealant on the wiper panel may have been the problem. So pulled it out, scraped off everything and fashioned a new gasket from butyl rubber. I also did the center access panel since it was the same way. The passenger side seems to be ok for now, but i’ll probably repeat it on that side in the coming weeks.
Finished pulling off one side of the inside skin, chair rail has rusty spots all down the line.
This center section is the worst, both the chair rail and the window rail are mostly gone. There is a very large crack in the window frame that has been letting water in for a while. This is where the bathroom is going to go so i’m going pull out the entire window frame and just skin over this section.
Surprisingly the lav area wasn’t too bad, I figured it would have been the worst.
So the plan is to needle scale all the rusted areas, treat them with corroseal and then liberal amounts of oil base paint. Then going to fill any small gaps with expanding foam and do sheet foam in the large areas. Of course this is after welding in some new chair rail in spots.
Also installed a new manifold to replace the cracked unit.
The fun continues…..
Started raining hard yesterday and was just trying to track down a few noticeable leaks. While trying to find the source of a drip below the steering wheel I came across these two lines that were disconnected, they aren’t labeled and I can’t see any ports that they belong to. Anyone happen to know where they are supposed to go?
Got all the rear luggage racks removed.
Also removed the rear wall, which i’m glad I did, I was thinking of just leaving it alone originally. Ordering some steel and hoping that I can cut out and replace a few sections without taking off the rear cap. Looks like the retainers fell off the back of the lights which left them loose and leaky for quite some time. Going to fabricate some new retainers and re-seal the lights.
Today I was able to get all the overhead consoles pulled out and all of the plating off the luggage racks. The plan is to leave the stock seating for the first 3 rows and I want to leave the luggage rack over those seats.
I was checking out the air cleaner and noticed that the whole right side of the engine was sooty, found that the manifold gasket had completely blown out between 2 cylinders and caused the manifold to crack off on the end.
Going to call around to see if someone can weld/braze it back together or pick up a second hand unit.
Had a few more hours to work on her today.
Holding tank came out with too much fuss, just ripped off the fiberglass cover and undid the clamp that holds the tank to the chute.
Exposed the rusty bits, looks like the lav window has been leaking for quite some time and rotted out the whole floor in the area. Once I get the wood flooring removed I should be able to weld in some new sections.
So over the course of Sunday I was able to get it to this point.
The plan is to take out the floor to find/fix any rust and also redo the insulation with rigid foam. Also trying to clean out all the goop that is all over the place, thing smells terrible. I am planning on keeping the original AC system for OTR use since it currently works.
The pile is growing quickly!
So right now i’m working on cutting out the holding tank so I can get to the rusty bits underneath. Also working on rolling up the vinyl floor and will start pulling the wood up.
Let the nuttiness commence!
Found this MCI12 on ebay, was only 4 1/2 hours away from me so I took a chance and bid, ended up winning it and picked it up this saturday. Does have some rust, but overall doesn’t seem too bad. Under the lav is pretty chunky and probably will have to re-weld some stuff back in. Has a 6v92 engine that starts right up, doesn’t smoke and seems to move down the highway quite well.
The bus has air locks on the cargo doors, aux fuel tank and even came with 2 extra tires. The only thing it doesn’t have which I have to figure out how to add is cruise control. Gets to be a pain holding that pedal down for hours.
This is how she was before starting.
