Sorry to here for your loss on your 565 Don.
I have a few :?:s
#1 What happened to the original bolts :?:
#2 Did your builder replace your original oil filter adapter with another one :?:
#3 What was your oil pressure before you shut the engine down after it blew the oil filter :?:
#4 Did you receive the engine from the builder with the oil filter on & the motor Primed :?:
#5 Was your engine builder aware of the size difference of the adapter bolts prior to you receiving the engine back from him :?:
#6 If local, Did the engine builder offer to check out the bottom end after it popped the filter or did he tell you it would be fine with the repairs you made:?:
I know its alot of questions but all of them could be important on the final outcome of your delema.
I know it's not the answers you were looking for but it's hard for me to give you a honest answer with out gathering as much info as I can get with out sounding like I'm on a Witch hunt for engine builders due to this nightmare Im dealing with at this time .
Look on the brite side I'll bet your guy diddn't call you uneducated or that you must really suck at being a mechanic like my builder has said about me .
