John is right about liner corrosion on Rolls Royce engines.  With an Eagle, which is very similar to C range, it MUST be run with 50% antifreeze.  Obviously good quality A/F.  I am sure test running it without would not be a problem.  Rolls also supplied a corrosion inhibitor for use in sunnier climes.

thank you for the pointer John i put a 60/40 mix in write from the start so i'll top the A/F up a bit more as the truck has sat for a few years with no coolant in it at all.

I had an amusing incident with my dry sump C6 in a Constructor,  a liner seal developed a leak and about a gallon of coolant ended up in the sump.  On starting, the scavenge pump transferred the water to the oil tank with such force that it shot a jet of oily water about 10 feet upwards, fortunately the oil filler cap was spring loaded which acted as a safety valve.

Moral of the story is to always check the oil and coolant levels before start up after standing for a while, the loss of water could have been due to a head gasket failure which may have filled a cylinder with coolant.

interesting story luckily in my case the bottom hose had been pulled and all the coolant drain taps opened.

i put a bore scope down as many of the water ways as i could and they all looked very clear.

the oil cooler was in good condition and the sump was fairly clean as well so the engine at least had been looked after.

Glad to see that you're getting close, great looking rig... The most exciting part will be when you test drive it for the first time without the cab!

Indeed, for it would be a royal pain in the b----cks to do it twice on account of a bad throw out bearing or transmission... The work you're doing seems monumental, since all I have ever done are jeeps; and now trying to do a replica Chevrolet WA (30 CWT) LRDP,  which is a real challenge in terms of certain parts to give it some originality...
