Rebuild ideas and thoughts
I am going to do a custom rebuild of my motorhome as I got it fairly cheap, probably paid way too much for it. I like to customize things and finding out what works and didn't work. Below are some ide...

@hoosiermark, Yes more of a tinker toy, but do want to get it on the road after it is done. I am sure that when you built cars you realized at some points of the build on figuring out what the manufacture was thinking at the time they put it together. And there was certain times that probably you had caught something that really wasn't going to make it that much longer. Even with the newer Motorhomes, the quality of the build is good somewhat, but not perfect by a long shot. Yes, I am sure that it probably would be a lot less labor and not as fun to just go get a new one, (I know that if someone is getting rid of one) there is always the hidden truth, no history and end the long run might cost you just as much if not more to get it right. With this project yeah it going to take a while, but I will know this puppy inside and out, and the short cuts I take, well that would be on me if it breaks.
@rgatijnet1 - You make a very valid point on the spray foam, thank you. I understand that the reason that spray foam is the ideal is to make it airtight to keep all the drafts out while also providing that insulation barrier. I will probably go with that plan and look into the closed-cell. Lol, this is why I started this is to get ideas and brainstorm. Thanks.
So my engine teardown is complete. The good news is the block is so far so good as far as I can see. I do have the 4 bolt main, yay, that's a plus. Now for the bad, so while I was trying to get the crank to turn something was binding really bad, and did not want to force anything at this point. Long story short is the piston on #3 is collapsed enough to make the connecting rod float freely. Going to clean this up tomorrow to make sure that the connecting rod is ok. The camshaft is done, bearings all around will need to be replaced regardless, but was expecting to gouges and such in the walls, but looks good so far, going to bring my big light up there tomorrow then get it ready to bathe for further inspection. The valves, oh my, don't even know how or why the thing still ran for. Exhaust valves on Cyl 5 & 6 were burnt, all but two exhaust valves were stuck, stuck enough where my little 2 pounder didn't budge it, so the 3 lb worked after a few taps. I didn't want to do it this way but I have to check the valve seats and guides after the bath.
So here was where I was going with the what were they thinking part.
- Exhaust manifolds, not sure if many saw how much space the air tubes take up, but it is a lot. (going to load up pics)
- Timing, well it was time for the best to be changed, did you know that thing had a plastic rubber-type setup. (see pics, please don't mind my work shoes)
- So looking at the crank will be looking further after the bath, but regardless I have to check the block for scaring, there are so many burs on that thing, look like someone being lazy and didn't clean it up before install. The are a few nicks on the crank but hopefully, all will check good.
- This goes the same with the block, there is so much that needs to be cleaned up and smoothed out from the factory, seems like a disaster ready to happen. I'm not looking to make this into a race car, but do want or need it to have some power, and as far as reliability that is why I want to do it, I trust myself more than paying someone to do it.
- I am going to try and figure out how to upload pics, if anyone see's anything that may be suspect please let me know. And yes on assembly the shop will be a lot cleaner than it is.
