oil in the coolant and vise versa.. :(

Thoughts on the pic of the oil cooler removed

Pressure test the cooler.

Start by purchasing a can of MAF cleaner, give it a good cleaning and see if that helps. Cheap solution if it works. Just make sure you don't physically touch any of the sensing elements.

Good luck!

Time for a tear down. If you are still loosing oil (with no obvious external leaks) you are chasing your tail trying to flush. You have an internal problem. Best to get it solved before you grenade the entire engine...

+1 and then some. Water can't be compressed. If it gets into a cylinder on the way back up, you will break a rod and or the crank, i.e. grenade'd engine squared.

The good.
Oil has been changed a couple of times now with a couple of hundred spirited kms between changes...No more white smoke and absolutely no coolant in the oil. I'm now refilled with synthetic.

Coolant was flushed a couple of times, pulling the front bumper to get at the hoses, pulling the water pump and thermostat to removed any sludge. No matter how many times I flushed it with water I just couldn't get out all the sludge. I caved and went the cascade route which seems to be popular solution on the diesel truck sites. Throw in some non foaming cascade dishwasher liquid to help emulsify the oil. This seems to have done the trick. I have flushed it twice now with the cascade and the amount of oil showing up in the overflow tank seems to be getting progressively less. I'm still not 100% sure I'm out of the woods but it looks promising.

Surprisingly the coolant system on these cars seems to be excellent. We are experiencing a heat wave at the moment. It's been between 30-39 degrees for about a week now. Even with just water the car is holding steady just above 180. I would have to stop for a long time with the car running for the temp to climb at all. Even then it only gets have way to the next line and drops almost as soon as I drive away.

I'm still fearful of a blow head gasket but should know more within the week. I will continue to flush the system until I see no oil before putting coolant back in.

thanks for all the replies. I will let you know how it turns out..

Have you performed a coolant system pressure test..?

[Geof3]

Man oh man, I cannot fathom how you would have that much intermix from just the cooler going bad, but maybe? If you don’t have an internal problem, you should play the lottery, like NOW! Or, hit Vegas or something!

And, you still need to figure out why your MAF is unplugged...

Hi, It is still ok?

Im facing the same issue, even after an engine rebuild.

The mech said the oil coller was ok, but I still want to replace it, before i need to remove the engine again (3rd time)

Thanks!
