Diamond Reo, to be or not to be??

Hello, newbie here. Excellent site you have here, partly to blame for my next project. I have restored numerous cars and tractors and i think its time to move onto a truck. I have found a reasonable 70'

G'day norcoast and welcome to the forum. You will get plenty of advice here, maybe not all good. About the only rule here is we need pics and plenty of them. There are clues at the top of the page on how to upload pics. As far as I am aware the number of wheels has nothing to do with going onto club rego.

Hi Norcoast, it maskes it easier if you put where you are. It doesn't matter how many axle's in Queensland for club rego, you can even do a Road Train.
The 504 Cummins V8 185, will more than likely have electrolisys in the liners and will be cactus. You can get reasonably good 10.00 X 20 tyres from the wreckers for around $100 each, and then put 2 new 11R's on the steer, under $300 each.
Sounds like the truck needs a motor, and a good little V8 185 Cummins won't be easy to find.

if there is a crappy little V8 cummins in there ,, you can pi$$ it off and put a 6V53 jimmy -end of problem

no problems with club reg here in Victoria either but you will need a roadworthy

Could also be liner seals,has the coolant been kept up to it?Or put a crappy little 6v53 in it if you dont mind getting migraines

would a 903 bolt into where a little 504-555 once was ?
just a thought ..

NOPE!!

However the engine gets water in the oil, which could be just a head gasket or at worse a cracked head or liner.

most common problem with water in oil is liner packings.if its sat for a long time without starting it could also be oil cooler orings.
cummins v504 is 210 hp and was the better of all the small v8's.......the older 185 was only 470cu in.
a cummins head gasket wont give you water in the oil so best method is drop the sump and pressurise the cooling system....if the water drips from behind the liner its the packings,if it drips inside the liner between the piston its a pin hole from electrolysis,if it drips out the main bearing caps its oil cooler.
hope that helps,

Hi again, thanks for all the information, looks like its going to be a bit of a gamble between electrolisis destroying the block or just a few O rings on the oil cooler. If it is terminal I still think I will stick with the deep rumble of the V8 Cummins. Its hardly going to be driven so I dont want to spend too much on the engine.

I managed to post some pics on flickr, addy is:
