The guy I talked to was at Engines Direct....they currently have some remanned 6VE1 engines on ebay...and apparently sell remanned engines across the Country to numerous dealers, etc

He mentioned they had to replace the stock rings with a different type to fix oil burning.....

Their crate engines are all new parts with upgrades for $3400 less core of $425, shipping is $150.....warranty 3 yrs/unlimited miles

Here is their 800 number: 1-800-998-2100
