Ive yet to have a problem,But i am using a duttweiler pump
and the bypass for the pump is drilled into the fuel pump block off plate.
Which means the whole timing set is always getting an abundance of oil
when ever it is bypassing
There seems to be a compatiabitly issue with the billet roller drive gear,the
composite sensor drive gear has fixed that issue. As far as the austemper
cores there aren't any issue that I am aware of .
