Oil Filter Adapter

[Gauthier]

On the top side of the oil filter adapter, there are two solid plugs. Into what side of the oiling system are these two plugs sealing?

Thanks for the earlier thread. Based on jwilliams3's input, it seems that using one of the two ports for a bypass filter could reduce the oil flow to the turbo. Is this correct?

I disagree with jwilliams on this. The bypass arrangement increases oil system capacity by a quart or 2. Therefore, it doesn't decrease the amount of oil available to any component anywhere in the engine. In my opinion, based on what I know of the oil circulation system in this engine, there is absolutely no harm to your turbo bearings by installing a bypass filter in either port.



I plan to install a bypass filter identical to Amsoilman's in the outer-port (the one farthest from the block). That port will have a cross fitting on it so I can run an oil temperature gauge, oil pressure gauge, and the bypass filter. But I'm waiting until after my engine breaks in to get the bypass filter (I have a theory about the beneficial effects of small contaminants in the oil system during break-in).

I know for a fact that 2 bypass filters have a flow restriction in the input line to the bypass filter. Puradyn restricts flow to 6 gal an hour of engine running and Amsoil restricts to 2. 5 gallons evert 10 minutes.
