Keith Browning Posted July 21, 2008 Share Posted July 21, 2008 I was viewing that Motorcraft filter video again and wondered what the possible symptoms or likely damage could be associated with a broken standpipe? I looked at oil flow and oil is drawn from the crankcase, up the front cover through the pump and past the regulator to the oil cooler, then to the oil filter and finally the HPOP reservoir and the engine lubrication system. I would expect to find debris in the reservoir and anywhere in the engine. The small plastic pieces might not cause any major restriction but they could clog the piston cooling jets... I don't think breaking the standpipe would create too much debris but this also affects the filter bypass. Any experiences or thoughts?

Jim Warman Posted July 22, 2008 Share Posted July 22, 2008 We have at least two in our area that have had broken standpipes (that I know of) that have left plastic in the system from the tabs on the bypass valve... They are still on the road with no apparent ill effects..... yet. Both of these were serviced in aftermarket shops - in both it was us that found the damage.
