99 S80 Coolant Loss Diagnose
My friend are leaving US, and he would trash the S80 as it has a blown head gasket. I told him I will take care of it. Now I am the owner of it.
Head gasket symptom: Coolant loss due to water came out of tailpipe. Coolant tank smells gas like. Milky engine oil. Miss fire.
I am now trying to use gasket sealer to temporarily fix it. When I was flushing the cooling system, I found the driver side carpet was wet: heater core leakage.
Moreover, the cooling system seems to be under high pressure, the upper radiator hose was hardly to squeeze when engine was running. Is this normal?
I have a 97 850 and been working on it a lot. S80 is a little new to me. Is it similar to fix the heater core as 850?

There is circulation I think. The upper radiator hose can get hot when engine is in normal temp. The water is warm when I drain it after it got normal temp. This also indicates that the thermostat is good.

Progress:
Check the spark plug holes. I can see water in No.4. Oil filled No.6.
For heater core, I just bypass it right now. Cut the hoses and connect them.
Tech, how to disable fuel injector in S80? Just unplug the attached electrical switches?

While I checked the spark plugs, I found water in No.4 cylinder and oil in No.6.
Disable the No.4 injector will allow the gasket/block sealer to work. Let it fire will keep sealer from passing through the holes due to combustion gas pressure.
Am I right?
