There's alot of ways you can test your vehicle for head gasket ,but the best way would be a cylinder leakage test,because once you see bubbles going into your coolant reservoir/over flow tank confirms this issue .This is a DIY job
A blown intake gasket will cause the engine to run too lean, which in turn will cause drivablity problems. A blown head gasket on the other hand may or may not effect the drivablity of the vehicle and may not set the check engine light. Serious engine damage will occur if you continue to drive a vehicle with a blown head gasket. You can see any or all of these symptoms. White smoke coming from the exhaust, A sweet smell at the exhaust, Loss of coolant, Coolant in the oil, air bubbles in the radiator, engine miss. Either of these conditions may or may not set the check engine light.
An engine coolant leak, sometimes visable outside the block, sometimes internal mixing with the engine oil and sometimes both ways.
Depending on what engine you have,
Intake manifold; vacuum leaks, coolant leaks internal and/or external, oil leaks.
Exhaust manifold; exhaust leaks, backfires.
if it is just a blown exhaust manifold gasket it can ruin your valves, so replace it correctly and make sure everything is clean before putting on the new gasket
blown head gasket or cracked block blown head gasket or cracked block
replace the head gasket
The typical signs for a blown head gasket is white exhaust coming from the tailpipe, gradual coolant loss, rough idle, temp gauge may fluctuate a bit while driving.
Most likely a blown head gasket. Or if you own a GM it's probably the intake manifold gaskets. There is a class action law suit that has been settled , but getting any cash will be a chore. I have a 96 GMC and just changed them for the second time.
Intake manifold gasket

If it was removed then YES.
With a blown head gasket the engine will still run, poorly with issues, but run. A blown engine will not continue to run from that moment on.
Blown head gasket and/or cracked head.
Yes, the exhaust manifold on a 99 Chevy S10 2.2 will need to be be removed during the blown head gasket repair.
Yes, change both of them.
Leak or blown gasket.
Remove the intake and exhaust manifold, then remove the head.
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
The manifold gasket is the same as the plenum gasket. The manifold gasket is a barrier between the manifold and the engine block.
You could lose power if the exhaust manifold gasket has blown on a turbo equipped car because the turbo will not receive sufficient pressure. The turbo will produce less boost as it is powered directly by the exhaust gases.
