I have a 97psd thatís putting the coolant into the oil.

The oil cooler has been changed with new rings,
New water pump,
New injector rings
New head gaskets
New driver head


So far I have not seen oil in the coolant. But coolant in the oil, slime under the valve covers, white tip on the oil dipstick, and some white blow by.

I only put about a 100mi on the engine and the oil that was in it. Should I put new oil in it and drive some more and see what happens, get it pressure checked, or pull the engine, tear it down and check the block and front cover gasket?
Could the block be cracked?
How long does it take the oil to turn black?
Its only been 40,000mi since its been rebuilt.

pull the water pump and look at the front cover itself real good , i have seen the cover actually get pitted from the water swirling around in behind the pump and eat a hole in the front cover, not saying thats the problem, but sounds like a place to look , 100 miles isnt that many miles for the repairs that were done, you had another thraed on this problem, did you change the oil and clean the valve covers since the last thread

i just drained the oil and filter today for the next clean oil cycle and it was tinted green. the oil filter had a small streak of green coolant.

however, the coolant remains clean.
i will be taking the valve covers off this week or weeken to clean them and the breather also.

so your sayin fill it back up with oil and drive it like more than a 100 miles?

heres a pic with green tinted oil. normally the rotella 15w40 is brown. add some anifreeze, mix it and you get green oil. the coolant system had slime in it at one point but was washed with the cascade and now is clean. the radiator was blocked like 20% from what the radiator shop said as it was being rebuilt.

my only worry driving it a lot is that the breather clogs up and over flows into the turbo, and the concern for the injectors. they have 40k on them and dont wana buy new ones at the moment.

i called the mechanic and told him whats been going on.

he said first, fill back up with oil and drive it again. 100mi is good enough to figure out if the problem still exists.

if so, drain while hot, pressure check the cooling system. to do that jack up the engine in the body and drop the oil pan.

he didnt know if the turbo needs to be removed to jack it up.

does it? i think it needs to be removed to do that.

with the oil pan removed, pressure check the coolant system and look for leaks.
