So I changed my plugs tonight and I took it for a spirited drive and now my engine is knocking. Limped it home, checked the oil and it was near empty. It knocks over 2k rpm. No codes are thrown, I'm going to throw some oil in it tomorrow and see what happens. Pretty sure it's broken though :/

 

spark plugs not oil plug right?

 

Correct, I edited because it turns out I was near empty on oil. Must have spun a bearing

Not sure what to do from here... LS1 swap?

I have an 08 35S, maybe a vq37?

 

Wow... how you lose all that oil? No warning lights?

 

No light came on, now I have a damaged motor

 

Are there any signs of oil leaks in your engine bay?

 

No signs of leaks. Bone dry...

 

How come you didn't check your oil prior to replacing the plugs?

I find it amazing that some never check their oil.

So it's just coincidence that it started knocking when you changed the plugs? That is, plugs really have nothing to do with the rod knock...

What was the condition of the old plugs? Wet, dry, color?

 

Yeah the coincidence was that I decided to run the car hard after the plug change. Hit redline a few times, made a weird noise and lost power on the last run. Immediate knock and stalling ensued. NO OIL LIGHT

Condition of the plugs were dry and burnt looking.

 

How come I didn't do a lot of things...doesn't matter now.

 

Sounds like it's toast
Maybe you can locate a lower mileage salvage motor, or maybe, just maybe, something occurred that can be fixed at minimal cost. Good luck & sorry to hear of your dilemma.

 

Looks like a stock lower mileage replacement is around 2 grand shipped. That's according to ebay anyways.

It matters to others reading posts on this site that if they haven't checked their oil on a regular basis perhaps they should start to do so before they end up like you with a ruined engine.

You should change the title of this thread to "Never checked my oil, car now knocks."

Changing the plugs has nothing to do with you ruining a perfectly good engine that now knocks.

Not questioning anyones mechanical ability but a loose spark plug can & will make a disturbing knocking/ticking/pinging sound that is similar to a death rattle. Did you happen to have any trouble with removing or installing any of the plugs, like cross threaded or anything? Good luck.
