I have done a little research on the problem of blown head gaskets. It lists the following symptoms:
1. steam from exhaust when at operating temperature - not observed
2. emulsive colour in the oil - not observed
3. difficulty starting - not observed
4. stinky exhaust smell in the coolant reservior - it stinks but not of exhuast - more like coolant stink - therefore I say not observed.
Now the last time I posted a problem about my transmission you guys were very close, the problem was actually in the solenoid, not the valve body. However the whole transmission was nearly ****ed anyway, so a rebuild was unavoidable.
So based on the lack of symptoms, would it seem the problem is more radiator and hose focused rather than head focused. I will be trying hard to observe for water drips from now on.
