Seems sketchy. Were they like... ?

One piece of advice, since you had a code so quick: Take a mirror and check around under the hood. When I purchased mine, which also went through a dealer auction, somebody (dealer, PO, not sure) had used what appeared to be Red RTV high heat Permatex gasket maker to band-aid oil leaks from the valve cover. A few months of ownership and that 'fix' stopped working, which is where the 'fun' began and my issues reared their ugly head. A quick look with a mirror would have found that.



Not familiar with your engine, but if they were trying to pass it off as a solid engine, you never know what you might find.
