Pretty much what he said, it really depends on what your plans are for said hot rod There's a huge difference between working something out on paper and going "it'll work" and the truck having any degree of drivability about Paul

A Foden in Yanky land, surely a sin 🤔 lol Struggle to even Fodens in Australia, NewZealand still has a few though Paul

Totally open to correction on this I believe this motor is still a Thermodyne Econodyne was a 4 valve chassis mount intercooled motor It may also depend on the part of the world each of us is from as to what we call them Paul

I dunno why you would unless there is some drama with what you have It wont give anymore power or anything like that The old tip turbine is pretty proven and reliable Unless I have missed part of the story here Or are you looking at buying a motor like this from a truck and fitting it into a different truck ? Paul

And I dont think two valve or four valve made much difference if any to the torque quoted by Mack 4 valves were more efficient and gave better fuel economy Paul

This part of your picture show a coolpowered 350 Series intercooled tip turbine motor Thats a good page of information you sharex there Bob, thank you Paul

The original Maxidyne's only had the 1 intake tube in Australia It wasnt until the coolpower motor came along that two intake tubes were needed, however in Australia the second intakecame from a second aircleaner for the turbine and the other aircleaner was for the motor intake Paul

Welcome to the forum RoadRanger A interesting life behind the wheel Paul

Is that a train or a tram, think you blokes call them trolley cars Mack looks tiny in front of it Paul

Mrs Mack is very slowly in between this atrocious weather getting sorted, she never had that much wrong but I started fixing one thing and noticed something else not right and so on A bit like the little old lady that swallowed a fly, well I hope I dont have to swallow that horse lol To make things right is lot harder than to just get them going sometimes Paul

Even in Australia the same deal with logging on Joey I can tell you I am sure glad I live in Australia with our health care and not the US with yours Paul

From what I know and everyone knows thats two tenths of SFA the rails need to be fully seperated to clean the rust out fully to allow them to close up Apparently they allmost always spring back into shape when this is done So sadly I think you need to go all the way to get the result your chasing I have never done this and am only passing on what else I have seen or been told Get your self a 3/4 cordless rattle gun and get into it I guess Paul

Hmmmmmm Hope it all works out for you Joey Paul

Second book is called "Fifty Shadeds of Tarmac" https://www.goodreads.com/book/show/27427571-fifty-shades-of-tarmac Now me been me and been very different, I contacted the Andy MacLean direct and paid him so he got all the money and not the likes of Amazon etc Book turned up with a signed note inside That is the book KS shared, "Me and my Mack" You jokers should tell the chief cook and bottle washer and you might one for your chrissy stocking Paul

Well my 20 cents worth which is hardly worth 2 cents tells me if it was mine I would fill the bores with diesel and a little bit of petrol (gas for yanks) drop a rag in it and set the bores on fire until they burn out This heats the bore and hopefully allows some possom piss or diesel or what ever to get down past the piston to the rings I would do this a few times until I can see some results Then maybe try budging it a bit Drop the sump and see if you can shift any loose pistons up Probably only the ones TDC, may need a jack on the floor with a block of wood on the rod Dunno the more you can get moving before going crazy means the less strain on everything Anyhow thats what I would be doing Nice and gentle is the way to save money No swinging big sledge hammers belting the crap out of things One slip and you can really make some giant steps in the wrong direction Paul

It's a good read, theres a secobd book from the same author 30 day round trip in a new F model Mack Field of Dreams Paul

I would agree with this Paul

If you keep on just poking along like you are you might be surprised at just what can be achieved with out spending bugger all Nice and steady, you may get away with no sleeves or pistons or maybe you will need just one or two Paul

We nerd KS to provide some info on this, dunno how big that back is at but huge is a fare guess Looks like a Alsakan Freight lines truck, or that style of truck Paul

They would probably still be peeling my fingers off the steering wheel lol Paul

If someone is putting a lot of force on a crank to move a seized engine then pushing as sleeve out is well with in a possibility Then as Joey suggested these are a press fit or freeze and get back This is all gunna be a challenge with a pistion still stuck in a sleeve Anyway thats how I would deal with it Paul

Very good, please feel free to share any photos or memories Paul

Not a lot to add but interesting

I reckon your right, this isnt as easy to notice if you dont know we're to look The bolts towards the center of the camel back I doubt anyone can easily see from walking around doing a pre trip inspection So depending on how the conversation went with mechanic I can sort of understand how this could all unfold quite easily Gotta remember the mechanic can only goes on what is described to him and the driver can only describe as best as they can I dunno we need to try to not be to critical after the event Bloody lucky everthing survived the ass puckering adventure at 65 MPH I reckon, I know I would of had white knuckles pulling the truck up Anyway I'm sure all involved are well on the way to getting things sorted now C4Ed I'm judge you the truck or anything else just chucking some thoughts about A lot of the people on here are really experienced in all facets of Macks so dont judge them to hard as they can only call it like they see it Paul

Once you yank the heads, before trying to turn the motor make sure you clamp the sleeves in properly other wise even when you get this free your gunna enter the world of clusterfuckerie with a masters degree If you accidentally move the sleeves you will turn from adventure to a in frame rebuild quicker than you can say "bugger me" Anyway, it's all good fun and adventure so far Paul
