    Pinto block- oil pressure sensor port. Before of after the filter?

    I have been told, by people that should know about pintos, that the oil port in the side of the block (where pressure sensor goes) is after the filter. In other words the oil available there is filtered. I have found this to be incorrect. I fed my turbo from an adaptor there and got a blockage at the oil inlet of the turbo. I now have to get a new CHRA but this time will use an Aeroflow -4AN inline oil filter before the turbo.

    are you talking about the oil pressure switch port? because it IS AFTER the filter, but that doesnt mean you cant block the turbo feed though, fo rthat reason most to teh turbo yb boys run a filtered oil feed pipe

    I would still be concerned as to what blocked your oil feed to turbo pipe in the first place, is there contamination somewhere in your engine?

    I never realised running a filter in the oil turbo feed line was a thing... something else to buy to now, not risking this new setup!

    The -4AN line wasn't blocked. It was where the oil enters the turbo and passes through a 0.035" restrictor hole in the cage pin. Only a tiny bit of debris but enough to block the 1mm hole and starve the bearing
