The compression seems fine. Head gaskets often fail in a spot that doesn't effect the compression, so that is possible.
But in your case I would be quietly optimistic.
Flush, run for a day, flush again ect. Just use water, dont waste antifreeze.
others might have advice on what sort of detergent flush to use if the oil is stubborn to shift.
I have heard that acid or caustic flushes are not recommended, so probably avoid those.
Washing soda [Sodium carbonate] is supposed to be fairly benign.
I used it with no problems.
Yes. A breach between oil & coolant system will put oil (60psi) into cooling system (13psi).@FJ40Jim have you seen this before?
So possibly it could still be a head gasket? (fingers crossed)Yes. A breach between oil & coolant system will put oil (60psi) into cooling system (13psi).
Or just put antifreeze back in and forget about it! I cant recall who made the statement on MUD, but it is perfect for the 2F motor and your situation:
"It is too stupid to die"
If you know who wrote that, please give proper credit!
Yes, possibly a breach between pressurized oil and less pressurized coolant. Best place for that is the oil cooler. If not there, then HG, cracked head, cracked block are all possible.
But first, the oil & cooling systems need cleaned out, filled with clean fluid and test driven to see if symptom comes back.
