Coolant in oil.
My friends 88 T2 with a S5 turbo is getting coolant in the oil. I told him the only thing it could be causing this is an outer coolant seal is leaking or possibly the turbo. Can anyone confirm this? Or offer another theory?
Thanks in advance.
Thanks in advance.

This engine had water and oil mixing due to a cracked intermediate plate

Coolant in the oil happens very rarely and is NOT from a coolant seal blowing, it's from a cracked iron or bad freeze plug.
A blown coolant seal or groove puts coolant into the combustion chamber, not the lubrication system. The lubrication system is sealed from the combustion chamber by the side and corner seals, then the oil control rings and o-rings.
Please stop giving advise when you don't know what you're talking about. It has the potential to cost people alot of money.

Slow down a sec. Is it on the dipstick or is there just moisture in the fill tube? It is normal to have condensation building up in the fill tube.

Granted it is not very common but it could happen.

My point isn't that you're a dumbass. Cuz that probably isn't true. My point is that blanket statements are dangerous and have cost people lots of $$$ in the past. We don't even know the situation 100%.
Say this guy has water/oil mix in his fill tube, which isn't uncommon and he said it's just a little bit... which sounds funny to me because there's no little bit of water in oil. You get any decent amount in there and the whole mess turns white.
Anyways, He shows his buddy who thinks rotaries are pieces of **** and says he needs a rebuild cuz he's been waiting to say, "i told you so." You just backed that up and he might go out and spend $2500 on a rebuild +R&R.... meanwhile all he needed to do was take longer drives.
The dude asked for other theories.

That's a good point. But that doesn't warrant talking to me like a dick, nor does it explain this:

I know exactly what you mean about the water on the dipstick and what not and it is much more than that. The engine is getting enough coolant in the oil to make the oil milky after maybe 100 miles or less.
