OK so I bought another CSVT with a bad motor. I got the motor out and semi disassembled when I found the problem. It spun a rod bearin. It also blued 3 of the crankshaft counterweights  Where the crank was originally drilled for balancing the holes have burnt marks on them from heat. This sucker got really hot on the flywheel end of the motor. Now my question is....Is this normal for a spun bearing on these motors? Is it worth rebuilding or should I get another bottom end? The motor had 98K on it and also had a loose timing chain on one bank

Personally i would get antoher bottom end...it would be cheaper to fiund a low millage on then to get all the parts you would need for a rebuild.
Also, why not consider a 3 liter???? Im not sure if thats what you want to do, but that too would also be cheaper than a rebuild.

yeah a new 3.0 short block is like $500 from Bill Jenkins... I'm also in search of a used SVT engine to do the same. I figure I'll build it slowly and when I'm done, I can do the swap in a couple weekends... or so...  Where do you source yours from I checked greenleaf and car-part....

I think I spotted an SVT bottom end in classifieds for $300....

Well it smoked the rod bearing the rod and the crank is nicely scratched. it had a ton of slop  Personally I think the crank might be shot now. The cylinder walls look excellent..no ridge and they still have the cross hatching all the way up and down the bores. It's rather sad one bearing crapped out. I know of a 2.5L non svt motor locally....might just get that and swap the svt heads on it.
And for those wondering the car was in the classifieds and is from PA. I got it very very cheap 
also the oil that came out of the pump and oil galleries after the heads where off was nasty. It was really dirty and alot of silver to it. The rest of the motor looks awesome. Cylinder bores are great cams look good cam bores etc too.  WTF is the matter with these friggin motors????

Generally 2.5L SVT engine will not last as long as a standard 2.5L engine. These engines have bad/cheap rod design. SVT engines with higher compression put more of a stress on the rods causing them to fail.... If you do a rebuild get new aftermarket rods...
Many have said that these engines oil pumps cavitat when taking sharp turns, etc. Actaully from what I have heard on testing, it is plain and simple rod failure....not to mention cheap torque to yield bolts.....
3.0 rods are a little stronger and don't have the same problem as 2.5l engines from what I have heard.....

Bob

The blueing is normal. Don't freak out. Which bearing did it spin BTW???

1. Generally speaking you don't know what the hell you are talking about. 
2. Again you are completely wrong! There is plenty of real world data to go along with metallurgy to disprove that statement.
3. 10 to 1 vs 9.7 to 1 in peanuts in the grand scheme of things. Hey isn't the 3L 10 to 1 & run on 87 octane to boot.  That makes it break more rods and last even shorter then. Also refer to answer #2
4. Oil starvation is a possible issue with the 2.5L's lack of proper head drainage. (rpm and oil level exponentially increase the chances) However it's not the oil pump failing it's oil pressure drop from lack of oil in the pan!!!
5. Post these test results please and then refer back to answer #2 & 3. If you can't back up this hearsay while other data proves it wrong then why post it like it is gospel. 
6. They are the SAME [censored]-ING parts (rods, crank, bolts, studs, etc) Let me guess you heard this where you heard everything else right.
Doesn't that make it ZERO for 6...
Folks if you just don't know then please stop posting your _______ comments. Just sit back and learn something...
You see when someone that is actually trying to learn reads your post they might believe your load of [censored] and think it's the truth instead of the festering pile of BS it truly is...
I swear it seems half my posts are correcting other people's piles...

DemonSVT,
You know Demon, courtesy and respect are in VERY short supply in todays world.
My information comes from comments and observations that I have read/heard from Terry Haines and a few fellows over in England that have been discussing the situation with Ford engineers if I remember correctly.
Cavitation - The sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces. If the oil pump fails to have enough oil feeding to it what do you think it begins to do? I did not state the oil pump was at fault - did I?
Since you have left such a bolsterous message, may I inquire as the source to validate your energetic comments?
I am the first to admit that I am not an engineer. I again am commenting on converstations about this problem that continues on....I guess I really don't know much about the 2.5L engines in spite of the fact that I rebuilt my 2.5L and atx from scratch.......
Now back to my morning cup of coffee...
Bob
P.S. I just reread your message...You are just damn outright rude!
