is it a blown head gasket?

my coolant is all rusty and there are some drops of water under my
lid for oil in my engine.my radiator produces some bubbles when engine
is let to run for some time.does all this indicate i have a blown head gasket???everything else is fine in my car though.
and if it is a blown gasket , are these block seals any good????

that could be a blown head gasket. Is your car down on coolant and/or making white smoke out of the tail pipe? If so i would say it is probably a head gasket. I'm not sure how the block sealers will do for a head gasket problem i mostly use them for leaking freeze plugs and things like that. There is a kit you can buy that uses a dye and it can tell if combustion gasses are getting into your cooling system. You may want to go look into that is you don't want to pay a shop diognostic fee. Good luck with that and i hope it isn't anything major.

If your head gasket is blown internal there should be oil in your radiator or antifreeze in your crankcase,(by by bearings). Rusty could just mean you need a back flush. When your car has been running and is at normal operating temp. check your dipstick for water signs. When your engine is cold check your radiator and recycle reservoir for oil. If you got a blown gasket, replace it, dont try sealers.

there is no white smoke coming from my car and there is no
loss of coolant.the only thing concerns me is some drops of
water under the lid for filling oil on the engine.
and the bubbles coming out from radiator when car is let to run for
sumtime.my car doesnot over heat and my dip stick has no signs of
water.power is very much same.
