Someone recently posted some pictures of a factory 934 or 935 showing the turbo drained to the sump. Also, didn't the earliest Turbo Carrera's have the sump drain as well without an additional scavenge?
My take on the drip tank to scavenge pump adaptation is that it was to effectively drain the turbo on shutdown and reduce latent heat oil coking. For my use, sacrificing the drip tank and scavenge pump for an effective AC seemed worthwhile until my next rebuild at which point I will likely go to a mechanical scavenge system without sacrificing my cam sensor. However, I don't track the car or even AX at this point which I think would have a significant impact on the decision process.
