Apologies if I asked before....still wondering the finer details where oil feed begins for the turbo and where drains back to sump. Is it same ad ea82T is fed?

Oil feed is from the oil cooler adapter on the ea81, return drain is on the back on the head.

Thanks Brat man. So is it an oil cooler adaptor that fits on the oil pumps filter fitting pushing filter further from pump body? Not water cooled turbo?

Correct. There was an update to water cooled turbos for the 81t in 84, but not all cars were brought in for the service. My hardtop was only oil cooled until the day I replaced the engine.

Thanks. Helps me.
