I need some help finding this hose - 928 107 312 00

Is anyone able to find this hose in PET (Parts catalogue).

The hose is market with part number 928 107 312 00 (but this is not a valid part number according to Porsche. The part number has no succesors either.)

I have also attached a picture from PET of the "oil filler neck" - the hos I need enters the "filler neck" on the opposit side as hose number 55, in the same height.

Thank you.

 

On the GTS that hose (pointed at) is supposed to run over the intake to the other camshaft cover oil breather. That hose is not the same as 55.
Somebody correct me if i'm wrong.

 

They changed the breather system on the GTS multiple times over the years, so it's not surprising that PET is not conclusive. I can't even find the filler neck with the additional spigot on that side. What year is your GTS?

I have the breather spigot on the filler neck on that side too, but the hose on mine goes off under the intake, and not to the cam cover like yours.

Roger at 928's Rus should be able to track it down for you. The P/N seems about right for that area/group.

 

Mine has the side to side front of cam cover connection like yours Phil .... but they changed things so often on the GTS trying to solve oil consumption/breathing issues that this one could just be another version.

 

Thanks for all the information.

The GTS in question is a MY1992.

Thanks for the tip regarding Roger at 928's Rus.

 

The part number for the hose that goes from the PS to the drivers side front cam cover vent elbows is the one you see in the attached pictures

The hose that connects to the PS oil filler neck and from there runs under the intake manifold where it connects to the "Y" at the rubber transition between the MAF and TB is a different number

 

The hose that runs from the OFN to the "Y" for 93-95 GTS only is #928 107 316 00 See the attached picture

 

Remember that there are at least 2 iterations of the breather setup on GTS's. The OP's '92 and my '93 had an '08 filler neck, and the 928 107 312 00 hose running from the cam cover to filler neck as well:



'08 neck:




Note the bolt/plug/thingee molded into the nipple on the base, to block off one of the outlets:



Pretty sure that both the -08 filler neck and 312 hose are NLA.

I ended up using the -08 filler neck on my stroker, as it was a convenient way to re-route the breathers as Greg intended. If you just need a section of good oil hose to replicate the 312 hose, Greg's got a couple of rolls of hose that would work.
