Kota, excellent point about boost if it was at intake plenum.

Some adventure! Lucky you had Cummins do the work!

Richard suggested the heater core(s). And the hot water tank heat exchanger and associated plumbing.

I'd pressurize the cooling system and see where the water is going. The difference between 1600 rpms and 2000 might be more boost pressure at higher rpms preventing coolant at a few psi from entering the induction system.


When this happens, cylinder gasses over pressurize the cooling system and blows gasses and coolant past the pressure relief valve in the radiator cap.

What I would do first is to pressure test the cooling system, if this showed inconclusive results I would pressure test using dye.

If you have a compression leak this big, you will smell it in the coolant and or the exhaust.

The overflow should be full and overflowing. Should be a wet mess back there.

So, they dyed it, pressure tested it under load, and found cooling system is running at 17psi, causing the overflow out the radiator. Will isolate the air compressor, and determine if caused by engine. i.e. head gasket #3.

Not sure of your comment to isolate the air compressor but if it means they are going to pressure test the system with air make sure they remove the injectors before hand. If the leak is in the engine or head and back pressure is applied the coolant will flow into the cylinders and if started will cause a hydraulic lock. That get real expensive

The significant increase in the leak rate points to the last job as the cause.

This is, or has become, an epic adventure to Newfoundland.........pg 6 and Nick hasn't even got out of the US yet.

How long do you have before you're AWOL mate?

Cheers
Tony

The Cummins has a haldex air compressor that's water cooled. It has two lines that run to the rear of the block. Possible for a failure to pump air into the cooling system.

Very interesting point about the air compressor. It should be a very easy test to test the coolant side of the compressor for an air leak. Such a failure could move a gallon of coolant in 100 miles.

While a compressor leak of this nature is possible, it is very, very, very unlikely.

Did you figure out what caused the problem, and is there any advice you can offer to us other diesel 36 owners?
