REAR MAIN SEAL still leaking

[SOLSAKS]

newly built motor
shop that installed and machine shop have tried at least 3 times
to replace the rubber main seal

each time they were very careful
and did things as right as rain
but still leaks

they said they made sure all valleys etc were clean
( hope I am using right terms )

has anyone experienced this
that has advice ?

thanx

RTV on lower seal "wings" or "tabs" along with rtv on beveled area on lower bearing cap. Everything must be clean, dry, and free of oil. Also, must sit for 24 hours with no oil introduced (aka not running). There is a diagram somewhere on the interwebs, but someone here may have one.
