Hello spdsk8race and welcome to ...... The Forum ......
That code doesn't look good for your car. As mentioned, there has been a lot written about that problem, for your review.
You might consider draining the crankcase oil to see if there are metal particles in the bottom of the pan.
Is your car boosted..??
Have you tracked it ..??
Will it start and run at all ... ??
$15,000 sounds like a lot for a new engine ....
Come back.
