Water in oil

[Tim McCune]

After getting my 87 GN back on the road, noticed some steam from under the hood. Shut it down, checked and found oil was very, very milky. Pulled the radiator, had hoped it was just the radiator leaking into the oil cooler, but shop says no leak into oil cooler. Aside from a cracked block, what else can be wrong?

Should like you've fallen victim to a blown head gasket

Would hope for that over a block crack, of course. I left some info out -- I checked 1, 2,3,4 cylinders and good compression, then did a brief test for combustion gas in the coolant (one of those tests with the tube filled with test solution) and negative, no combustion gas contamination in coolant. Not sure if those items make any difference, if a head gasket break could happen where it couldn't show up with those.

And if you had antifreeze in the radiator your bearings are shot.

Did the head bolts have rtv around them? If not that's your problem.

Don't know. The guy I got it from had it worked on out in San Jose prior to sending it to me, spent a lot of money at a garage for what turned out to be less-than-satisfactory work.

Who's to say the guy worked on your car also took joy ride or test ride as they called it, and didn't see the danger sign before the head gasket blew.
What type of work did he do that you spend a lot of money on?

The main places where coolant can mix with oil are: Head gaskets, Front cover, oil cooler, intake manifold and a crack anywhere in the block or heads. Is there evidence that the front cover or intake was removed?

The previous post about coolant (ethylene glycol) in the oil is true......it destroys the bearing almost immediately......it sucks

If you have any mechanical skill, it is time to explore and find the cause. The engine is going to need new rod, main and cam bearings either way.

what about compression on other two cyls?
