You might have a lim gasket Failure. Please stop driving the vehicle. Once you have diagnosed if it is or isn't the Gaskets. Change the Oil Immediatly You don't want Coolant in the oil as it will rust the bearings.

Yes they do. The upper is one piece and is a paper like gasket. The lower has four pieces and is pictured below.

I just replaced mine last weekend.

In reply to a PM:

Your SSEi has a paper gasket between the SC and LIM. It also has two yellow coolant o-rings. Your LIM has 4 gaskets between it, the block, and the heads.

The most likely leaks are at the TB gasket or the LIM gaskets. But with those miles, you should just replace them all. I can do the whole top end in about 2.5 hours on an L67 or L36, so even for a first-timer, it'* a one-day job. You should replace the black plastic coolant fitting on the waterpump end of the LIM with a replacement metal fitting from the dealer while you're at it.

92 ...There is not a cooling "elbow" on Series 1 motors. It'* called a cooling "outlet".

With over 100K, one would think the plastic was already replaced with a metal one by this point.
