Engine blown?
 

yesterday i went to the drag strip, I pulled a couple runs and i was pinging
on the way back home on the highway i was in full boost and all of a sudden i see this heavy white smoke coming out of the engine bay, so i pull over to check it out. I could not see where the oil came from, its everywhere , i lost about a liter.
I noticed the dipstick was out, could the oil come out from there?
did i blow something else?

The car starts, i even drove it home after i topped off the oil.

you pressurized the crank case. either by bad rings or bad valve seals or bad pcv valve or a combination of those.

+1 Have a leakdown test performed to properly diagnose the engine's leakage.

Does the car still ping or knock? Did it quit smoking? Is it missing? If not you are probably ok.

You have to check for leaks to see if you blew something else. I've heard of people loosing oil that way. But I have had my car blow oil out the filter on the valve cover. It blew oil straight onto the exaust and smoked like a chimney.
If it blew you would know it. I wouldn't drive it pinging. I would tow it before I blew it.

I use a 323 turbo pcv valve on my car. If you don't have one you can pick one up.

you may have to change your screen name...

It doesnt ping anymore since i lowered the boost,it dosnt smoke either, the smoke was just from oil on the manifold

Look who's talking....maybe he should try some head gasket stop leak in the oil to stop the leak

EDIT: OP, If you haven't been around long enough to get that little joke, do not try head gasket stop leak in the oil....it doesn't work...mouglie can vouch.

i had same thing happen not in my miata though bad rings and bad pcv and also partly my fault i had pulled the dip stick tube out and lost the 0-ring and installed it without it

hahaa, i'm just kidding yo!

good luck with your car aigh...

update: I drove my car today for the first time since, it misses, its drinking oil like crazy, and theres exhaust fumes coming from the valve cover
headgasket?

Do a compression and leakdown test before pulling it apart. You could have more than one problem.

white smoke = coolant

""I could not see where the oil came from, its everywhere""

wow lol

check the pcv, see if u grenaded it, im guessing head gasket if the car still ran but shitty. i pressurized the crankcase on my old red one, and that wasnt pretty. Oil fucking came out of everywhere. It was like hey im from the wood work and id like to cover your engine bay. However, i only did it at like one psi and let off quickly when i saw the oil pressure jump and felt the car stumble. That one psi covered my motor bay with oil very quickly, it came out of gaskets and everything, dip stick popped and all. But this was like a half a second mistake. Im assuming that if u held it for longer, you would see all kinds of fun things. Check your compression, and do a leak down. This will at least tell you where to start on your problem.
