Oil Lines

In the factory set-up...

The oil coming from the engine is first routed to the oil thermostat, at that point it either goes to the cooler or back to the oil tank or a mixture of both if the thermostat isn't fully open.

The thermostat has a pressure relief valve which will bypass the oil cooling circuit should it be restricted. So your oil pressure shouldn't drop. But you are burning power by maintaining a pressure adequate to hold open the relief spring due to the restricted oil line.

I repair 911 oil lines as a side/hobby...

I'm prepared to build some for the 73 cars from newer lines... Anyone interested?
75 911S 3.0 to 3.2 now to 3.4 Twin Plug (Inwork...)
