OP just wait til the rod comes thru the side of the block

If the noise goes away when you accelerate it is NOT rod knock. I think it sounds like a top end noise but hard to tell form a vid over the internet. Could also be a chain slap issue, I'd have a look at those guides and tensioner.

Thank god!! Just curious, if you paid the car off within ~30days of throwing it on your credit card why didnt you just pay cash for it? Credit card points?

yeah, but the OP wasnt the original owner for the original 100k...plenty of owners have put 200k on their car...

Nitrous kit will add more oxygen which will help the knock sound go away... Or dump two bottles of seafoam in it and Rev it to 6 grand and hold for 4minutes 3 secs and 2 milliseconds... The second method is on a budget.....


In all seriousness check compression... If it checks out then hope you have another vehicle... Take it to a reputable shop get a second opinion... If internal no point in cracking it open to fix... Drive till it dies and have another engine ready to swap in... That's what I would do...o and change your screen name... It ain't bad *** no more
