So i was cruising in my turbo civic the other day and dropped into 3rd gear and heard a very loud pop. i wasnt over 5000 rpm's, but now when i drive the car its alot more sluggish. i feel like i have no more power. im not loosing coolant or oil so im not sure what could be the problem. It doesnt smell like im burning coolant but when i start the car up fo the first time after sitting a while it shoots out black liquid from the exhaust for a second. What could be the problem

 

That black liquid is just condensation mixed with carbon

check your plugs

 

only things that pop are intercooler couplers and headgaskets.

 

Could I do more damage to themotor if I drive it for a couple days and it is the head gasket that blew

 

yes

 

sounds like a coupler popped off to me

 

Is it making boost?
