41 0 MOPAR PERFORMANCE PARTSfrom the pick-ups all the way to the tank. Having three longoil lines running to the dry sump tank adds weight. So, if thedrawing is modified, we can have some problems. If youonly run one line from the pump to the tank then you mustuse a #16 line. In an arrangement such as this, each scavengesection of the pump feeds into a manifold that has three #12size inlets, and one #16 size outlet. For reference, a #I2 linehas a diameter of approximately 3/4" while a #16 line is 1inch. This allows our new lightweight system to make asmuch power as our earlier system.All Lines Shouk Ie%*lZlete Frmt ScavengeBall Plate TODrag 011 PanFlmr shouldbe angled backand lo the nghluilh car on lwelgroundVenlcal BalmUnder X3 Main CarFigure 7 - 35Figure 7 - 32Figure 7 - 33OIL PUMPThe positive-displacement, gear-type oil pump is driven bythe distributor shaft, which is driven by a gear on thecamshaft. The pump is integral with the timing case cover.A cavity in the cover forms the body of the pump. Apreissure relief valve regulates the maximum oil pressure.Oil pump removal or replacement will not affect thedistributor timing because the distributor drive gear willremain in mesh with the camshaft drive gear.Oil Pressure Relief ValveThe: oil pressure relief valve is not adjustable. The springtension is calibrated for 5 17 Wa (75 psi) maximum pressure.In the relief position, the valve permits oil to bypassthrough a passage in the pump cover to the inlet side of thepump (Figure 7-36).Figure 7 - 34
