Burning shit tonight of oil

So I have a mazdaspeed 3 2007 with 132000 miles so what happening to me is I just changed out 1 injector which was always open and after 20 miles my car started to smoke suddenly like the car was on fire and after 20 miles of driving I lost more than 3 quarts of oil before that it was burning no oil really need some help

 

Did you replace it with a cleaned / tested OEM injector that has new o-rings and seal?

If it was running fine before, sounds like something got unplugged, left un-attached, or similar. Could be an oil line came off, possibly near the oil filter if you were messing around near there, or a coincidental oil feed line breakage near the turbo. Have you looked under the car to find out where it lost the oil?

 

3 quarts in 20 miles is a TON, the car would drive like total garbage if it was burning that much. It is likely there is a leak somewhere and it is just puking it out.

 

All injectors probably were leaking and new/rebuilt injectors plus $200+ in o rings on them plus a set of Corksport injector seals is how I would have done it. Wait. I actually did it. But you have a massive leak. Time to go underneath and look at everything
