2.5T Blown Head Gasket?

[yanga001]

Go out when the engine is stone cold, don't start the engine, unscrew the coolant cap, is the tank pressurized?
does it hiss when opened cold.
Carefully examine the coolant bottle for any faint white chalky deposits.
If yes to those 2 tests I would get a bottle of block tester and see if the fluid changes from blue to yellow when idling.
That would be definitive to call the gasket.

If its limping along ok for now I'd be more concerned with the oil leaking on the belt, it could easily skip teeth.
Assess the coolant leak but attend the oil leak or you might be in for a $1000 rebuilt head too.
Most often its a cam seal. Not a huge repair but you're in Colorado? eesch thats gotta be cold..

So I remembered to test this today finally. This particular Volvo does seem to have coolant pressure still when dead cold. I did not notice any chalky deposits in the reservoir.

However, this Volvo still passes the block test and my two other white block Volvos also seem to have coolant pressure on a dead cold engine (and those I am not concerned about head gasket integrity on).

What do you think?

I had a 98 V70 with a slightly compromised head gasket for over 2 years. Biggest issues at the end were hard, misfire based, starts due to the car having some coolant in the combustion chamber. These volvos can fail where its a coolant into the combustion chamber that does not result in oil/coolant mixtures.

Unfortunately, 1.5 miles is enough to do the damage. My V70 got worse when i went 1km in -15C and the temp guage went slightly above its normal position.

My trick for these tests was to take the coolant bottle and lean it such that the fluid covers the bleeder port (small hose). If bubbles come out then it means coolant is being replaced by gasses which are coming from the combustion chamber.

The turbos are identical to other makes, and i believe it is a coolant cooled turbo. Check the lines around there. I had a TD04 crack its coolant jacket and leak a bit of coolant. Head gasket sealer fixed it funnily enough, specifically the blue devil stuff that reacts on contact to air when it is up to temp.

Overheated inline 5 is worth its weight at metal recycling, nothing more. Even if a fix is attempted, it will be plagued till the end of days.

I've heard situations where the head gasket can sink into the block or depress it basically, I've also heard of the sleeves actually moving/dropping(but usually for generic sleeve replacement and not say Darton).
