That whole 993 oil filter console retrofit is pretty interesting. Definitely something to consider if/when the engine is out and being rebuilt.

I wonder what kind of reconfigurations were required with regard to the oil lines.

Also, that "tank > engine > floor" diagram had me LOL at lunch. The group of people I was with thought I was going crazy.

Wait...I think my understanding of the circulation has been the wrong way around


But, but but...the oil gets filtered *after* the motor? Shouldn't it be before?

Because Porsche, I guess..

I guess the idea is that short of user error or outside of "standard operation" oiling system fcukery, the engine would be the only source of foreign matter in the oil.

Brilliant! (Shouldn't there be a really smoky heat exchanger in there?)

I'm reviving this thread to ask this question. To avoid the problem noted in the quoted post - could you pour oil in where it is normally added and have that oil drain out of the pipe going into the bottom of the engine (assuming the pipe is disconnected because the engine is out of the car)?

Here is what I have and really need to know what is the INLET and OUTLET at the oil filter.

Green - after filtration
Red - before filtration
Yellow - oil cooler (bypass)

So you would pour oil in at 13 (top of the black line) and drain it out at the end of 24 (the pipe running along the bottom of the wheel well on the passenger side of the car that attaches via hose #26 to the oil tank). I'm asking because I changed the hoses on the oil tank while the engine is being rebuilt. I cleaned around the area before installing the new hoses but I also had to cut the old hoses out. I'm worried I might have knocked some debris into the tank outlet hole in the process. I don't think I did but this would be cheap insurance for the costs of a couple quarts of oil - yes?

Thanks Ricardo. I'm going to seem a bit dim here (maybe "am" rather than "seem") but I'm having a hard time corresponding the location on line in this diagram to the actual parts I'm looking at in the car. As I look at the car - line #13 in this diagram would be right above line #15 on the oil tank. Line #'s 12 and 14 are closer to the top of the oil tank. Am I reading this wrong. I'll order the book. Thanks again.

Jpoint, I have not really worked in this area yet, it is on my list in my C4 project but I am not there yet. So I have to defer to others to help you out as I don't have a mental map yet of the various bits and where they physically are in the car.

Thanks Ricardo - just to be safe I pulled the hose and pipe going to the engine and check the line for debris. Everything is clean.
