I'm sure you meant "where can coolant be leaking into the motor oil".
The most common point on a 22R is inside the aluminum timing chain
cover right next to the chain. When the original chain guides break
(especially the plastic types) the worn chain stretches enough to rub
against the inside of the timing cover, and eventually wears a double
groove through the aluminum right into a coolant passage.
I thought that 81 22R's had metal guides that resisted this type of
wear, but there's a good chance that the head gasket and chain have
been replaced already along with the new plastic type guides. They are
quieter, but can break and cause this problem once the chain stretches
too much. Or maybe I'm thinking of the 20R....
If you hear an arythmic rattle or chattering from aproximately the
waterpump area with the engine idling, that means the
chain/gears/guides/tensioner kit needs replacement, and now the cover
needs replacement as well.
