Only if the cooling system is out of antifreeze. Also a blown head gasket will cause overhiting if the rupture is on the cooling system side, will empty de system by burning the antifreeze fluid and for that cause a white smoke with sweet smell out of the tail pipe; if the rupture is on the oil side will cause a bluewish smoke and increase your consuption of oil; if your car does not have those syntoms more likely your not having heat could be for other reasons, bad fuse, bad blower, bad switch, bad control, etc
No
I blown head gasket can cause an engine miss which one cause a rough idle.
No, only a blown head gasket or cracked head will cause coolant to mix with the oil. A leaking valve cover gasket will only cause oil to leak onto the engine block externally.
It could lead to it indirectly, but it won't be a direct cause.
yes if its stuck closed.
Yes, I blown head gasket will definitely effect the emissions.
No, a normal tune up cannot cause a blown head gasket. A blown head gasket normally is caused by an engine overheating or by a defect in the gasket or head. If it happened right after a tune-up that is just a coincidence.
the blown head gasket would make it over heat. but it wouldn't cause the heater to blow cold, it should actually blow hot if that is wat happened
You have a blown head gasket
There is a strong possibility that you have either a blown head gasket or cracked cylinder head.
I have a 1990 Mustang 5.0. I know for a fact the head gasket is blown. Every time I open the radiator there is a release of pressure. So my answer is yes.
yes
