Hi, just wondered if anyone has used a oil cooler sandwich plate for oil return from a turbo rather than modify a sump ? Or think of any reason why or why not ?

Cheers

if you mean as when fitted to the filter, then that would be on the pump pressure side rather than a open return

Hmmm... your right i think, cannot go that route then o/ .Saw what looked like a sandwich plate on good old eBay advertised as a turbo oil feed return, never heard of it before.

Cheers

I've seen crankcase breathers, oil filler caps and dipstick holes used for turbo oil returns but as said, the oil filter assembly is on the pressurised side of the oil pump.
