Superior Use Auto Parts Purchased a used engine for my Durango for $2050 they said it had 43k miles on it. engine had no oil pressure Gibsonton Florida

I purchased a used engine and transmission for my 01 Dodge durango for $2050. they said the engine had 43k miles on it . we installed the engine ( it looked worse than the one i pulled out ) we started the engine and it had no oil pressure. I called Superior Used Auto Parts and they said the engine was out of warenty . I pulled the drain plug out and couldnt get the oil to drain due to the sludge build up . this engine has alot more miles on it than they stated.

Im going to tear it down and take a look at it ..  I checked with the BBB and they have a "F" ratting wish I had check them out before I did business with them. they have only been in business for a little over a year and I read 45 complaints on the BBB 's website , they were all stories like mine.!!!
