Oil in coolent

The '91 Sami that I have had what looked like sludge in the overflow bottle. I cleaned it out, thinking that it was just a case of crud buildup. Now it's back in there.
The crankcase doesn't show signs of water in the oil.
Could this be one of those cases where the headgasket was put on backwards? The guy that I bought it from had rebuilt the motor "supposedly" just before I bought the car. And.....I'm not sure he knew about working on Sami's. When I read an earlier post about engine rebuilds, Glenn Wakefield made the comment about the headgasket is easy to install backwards, so I got to thinking that maybe this could be the cause of the oil in the coolent, since he said that it could affect the oil passages.
I haven't flushed the system as yet, but had planned to do that soon.

Re: Oil in coolent

The backward head gasket makes itself known right away.
(The cam seizes up and the engine don't run no more..)
You may have a leaky head gasket or a leaky manafold
gasket. Do a compression test and see what it looks like.
if the 2 center cylinders are down about the same amount then you may have a blown gasket. or if any one is low,

Re: Oil in coolent

...Or... you could just have a very dirty radiator and it's pushing it out the overflow. Have you flushed the radiator system? Obviously, now would be a good time since there is crud in there.
my 2 cents...
