Lesson to be learned here is - Never buy a used engine that you cannot hear run and test compression and stuff on, unless you are getting known to be good parts with it and not paying more than scrap weight.
Even an engine that was running good when pulled must have every opening capped or it is subject to damage.
I saw a 402 Chevy that was not buttoned up - Had mice crawl up the headers and nest in the heads.
I've seen mud daubers get in places where you would not want them - which is pretty much anyplace.
Do not leave anything open to the air - such as injector lines, injectors, anything else. I have seen a lot of engines that were worked on over the years, fail for unknown reasons.
I always have to wonder if possibly something got someplace where it should not have. I cringe when I watch most mechanics work. If there's an opening / plug it.
I've seen pieces of dirt fall into spark plug holes, bugs in engines, Lots of stuff.
Saw a 6.5 diesel that was not buttoned up have water damage from moisture that got in through an open exhaust valve.
Used engines and rebuilt engines are not worth much more than scrap unless you are very familiar with them
My new Mopar crate long block was about $5300. I would not invest to heavily in an unknown engine
Like I said, Used engines are worth scrap weight, Unless you know for sure about them - otherwise you just as well play craps or blackjack.[/quote] darn skippy brother very expensive lesson very well learned,..all the more reason to alert others of this practice, if said individual played on my lack of knowledge on this ,I'm sure there are others,..the idea of him doing this to others (as well as what he may be gundecking under someones hood),needs to be addressed by the honest vendors, the ones who literally would go out of their way to make a situation right. That truly and honestly care,Clearly from all that phone calls Ive fielded this person has been exploiting this site before he became a paid vendor, and as someone who subscribes for the help of others on my CRD,it stands to wonder how this misrepresentation brings down a good image set by people that worked hard on these things, to have a very good forum, A very good way for Newbies like me to understand the CRD world, to get the right information and appreciate Crd ownership, certainly not what I've gone thru,I hope. but i agree less trust, and do not go by someones gut word, this is a very expensive lesson indeed.

I learned this lesson a couple of times - but only to the tune of $300 or so. It took me a couple of times - slow learner - but the were not terribly expensive lessons
