Z Whip LS Oil Galley Diverter Restrictor Barbell. Replace your old worn-out LS Oil Passage Diverter to prevent oil seepage or oil bypassing the oil filter. Non-O-ring end goes into block 1st. If you are not sure if your rebuilt or fresh rebuild with little or no oil pressure is missing this, you can remove the rear threaded oil galley plug above the oil filter location and see if you can see the shaft of this barbell through the hole. This installs in the oil galley hole behind the rear engine cover on the rear of the engine on the driver side.
