Not in '86. At least my US 1986 does not have one, I had to add.

How feasible is it to put an inline filter in the return line?

Is it really that much of an issue? What problems can you point to arising from this?

The fan was added in 1987 (my mistake).

People have added filters (including Jim Fairman, the late Cole, etc), and another very trick fix (Cole did this, too) is to re-route the return hose from the scavange pump to dump into the crankcase breather cover - that way, the oil is picked up by the main oil pump an sent to the main filter before going to the crank, cams, etc. That is a project that I plan to do, but haven't yet.

The main problem with the OEM setup is that if the turbocharger bearing cartridge cokes the oil that sits in it at shutdown, the coke particles end up in the oil tank and then get distributed throughout the engine - biggest problem is the particles plug the cam spray bars.

I have owned my car since 97&thanks to a few good guys/gals here i just recently learnrd that the fuel pumps was ran on one circuit,all the dash lights were ran on 1 circuit,head lights on one circuit,i wonder how many 930s& assume 911s have caught fire from this poor design?Also wondering when Porsche corrected these problems.
