Sloshing in dash and coolant not returning to radiator from overflow

Here is an update on the head gaskets that I replaced.
My leak was occuring on cylinder 4 and 6. I guess alot of failures are happening there.
when the gaskets were pulled I could see where it was leaking.
symptoms were:
gurgling coolant in the heater core while accelerating
slight sweet smell from exhaust
spark plugs 4 and 6 were slighty different than the others, whitish deposits
doing a vacuum check on the coolant system. It was not holding vacuum and you could hear gurling in the block...

toyota head gasket kit $220
head bolts $180
machining heads $225 machined .006"
and a few other tools and parts..

I have a 175k miles and It should be good for another 100k miles

In conclusion if you cant fix it yourself, put your seat belt on and check the air bags..

 

Sub'd. At 178k and after reading this thread I think i hear this noise.

 

subbed, i'm at 175k and I think I heard this noise yesterday.

 

O7 tacoma 4cyl...368000... Same problem I guess after listening to you guys I should assume head gasket as well

 

So being that I don't have 3 or $4000 to have the head gasket replace what's wrong with pouring in the radiator substitute to seal the head gasket
