Sorry, classic v4 sti
Do u have the baffled sump or the plate?
Cosworth stuff is savage money i know its good quality and performance and thats what u pay for probably...
Jasus that's bad luck man sorry to hear that
What was changed in the new engine build did you RE use any parts that you could say effected the 2 engine
Second engine failure was taking a roundabout normally or are you acting the maggot on roundabouts?
Original oil pump and pressure release valve are iffy from factory in classics
Something like this baffled sump be the way to go
