re

I did hear leaking at the throttle body, and at the adjacent cylinder to the test.

On the face of it, that would imply a leaking intake valve,
plus possible head gasket or head thing.
what are the compression readings ?

Does it run at all ? If so, how well ?

Diagnosing what is exactly wrong with this engine was put on hold due to some family  issues tis summer.  Originally the list thought the oil cooler may have failed, which I replaced, and although there is no longer oil in the coolant, the power loss remains.  I have checked the cat which you can see daylight through, and today did a leak down test with a borrowed tester.  The short of it is that there is definitely leaking going on.  I heard no leaking at the exhaust nor did I see any bubbling at the coolant reservoir.  I did hear leaking at the throttle body, and at the adjacent cylinder to the test.  Am I correct in reading this to mean cylinder head/gasket issues and perhaps leaking valves?  I am still trying to get this engine running and would prefer not to rebuild the bottom end.
