There was a loud pop under the hood now car runs rough and smokes from under the hood


Could be a lot of things, blown head gasket, could be steam and not smoke from a heater hose etc.

Went to start car, made LOUD POP NOISE, then smoke poured out from under hood?? Is my car even fixable??


Depends on what went pop. What color was the smoke? If it was white and the engine was hot you may be lucky and just have blown a radiator hose. If the smoke was black or blue that would be more in line with an oil leak which may still not be the end of your car. You need to have someone look under the hook and determine where the pop sound came from.

1990 Geo metro popped and poured white smoke out


its a GEO POPPER.
"no oil up on crank case"

no idea what that means.??????
yes PCV valve. do clog.

white smoke at end if tail pipe.
you didnt say where,?

white smoke has 2 reasons.(tail end)
Steam and oil.
steam goes away fast and looks just like moms tea pot. and smells sweet, like the antifreeze in engine. (rad cap off ,sniff sniff, cold engine)

oil burning, smoke is very very slow to go away.
and smells like , blush burned oil.
if not sure what burn oil looks like or smells like
take out the dip stick on a hot engine
let it drip to the hot exhaust manifold there.
now you know. and is a key diagnostic skill.


no oil seen on dip stick end?, you mean that?
well you need to keep that from happening,
doing weekly service, and for sure old cars.
26 years old.

low oil invites blowing up a good engine.
for sure.
if it did that smoke is oil
if it did 10x worse, both .

my wild guess is you meant to say
I didnt see oil leaking on top of engine.
right?

if the engine backwires to the air cleaner
you forgot to replace the cam belt every 60k miles
the pcv will also be clogged, on cars not getting proper service, super colon.
if the PCV clogs,engine may leak oil bad.

this engine btw is a G10 3 cylinder.
with TBI injection.
we can talk TBI all day, owned one.

white smoke can come from many places
exhaust manifold, leaks of oil can land there
engine can back fire to air cleaner making smoke.
tail end.
steam is much worse. ill not delve in to that yet/.

Sounds like you have a major electrical short somewhere. If you are not mechanically inclined, you might consider in having a professional take a closer look at it.

My 01 gmc jimmy made a loud pop and white smoke started blowing out from under the hood. Now it makes a knocking sound but not like its low on oil or inside the motor. I dont have water in my oil and now...


The smoke under hood means that u need replace gasket between exhaust pipe and engine but smoke and knocking is not very good, it looks like your engine pistons has cracks and u r loosing oil by smoke time to time, i'd buy used engine from crashed car with less miles on it
