stumped on where coolent is going???

[threedogs]

could test for coolant in the exhaust?

[Stropp]

Ok. So I guess atm it's a wait for further development is it??

No mate don't wait, take it to a radiator place or a mechanic with a pressure gauge that fits on the radiator cap hole and pump it up and wait to see if it leaks down. If you can't find the leak like that then it's internal which is not what you want. Get it checked ASAP so it doesn't become something too big.

Yea good call mate.

X2 westy do the bleed down test it may be a minute crack in the bottom end of the bore .If it leaks down take the head off and see if 1 cylinder is cleaner than the rest after a run to get the block hot thinking diesel here .

A couple of things that won't cost you money first.

Get under with a bright torch. The coolant will be either green drops that don't dry up, or as mentioned, white residual that might be power when touched. Try and look wherever the coolant goes - turbo, joins in the hoses, the closer joins in the exhaust. Under the coolant overflow bottle.

Fill it up again, and see if the level goes down even if you don't drive the vehicle. How soon does it disappear after driving?

I went over it this morning.
Started it up and nothing.
I did get inconsistent bubbles threw the cap which tapered off to basically nothing after a minute or 2 so I'll assume that was an air lock.
It used another 1ltr again in 300k. So it's either developed when I was down Beachport new years, or its got worse quick.

bugger i would hazard a guess at the head gasket

[mudnut]

Are you able to to the same test as I did on my RB30?

That is to take off the fan belt, to stop creating bubbles due to cavitation.

Then have a half bottle at a bleed point near the head.

With the radiator cap on you watch as combustion gasses are forced out of the hole when the engine is revved.

The RB30 can be idled for 5 to 6 minutes from cold without the pump

But because yours is a diesel is that sort of a test not possible or not recommended?

Wouldn't any of those bubbles just come up threw the bleed line to top of radiator from the thermostat housing??

[mudnut]

A mate of mine told me to do the test that way as the Rb30 has a bleed point at the housing at the top of the engine. That is why I asked if yours is the same and if it is recommended. Sorry for the late reply.
