: Just checking to see if anybody has tried this - : The oil pump moves the oil and discharges it right at the point where the pipe fitting is at the skirt of the block.It then runs through a couple of slots cut into the pump body up into the center camshaft bushing area, then up the distributer shaft and forward into the front of the valve chamber. : It appears that if the slots in the pump housing were brazed closed,and the pump housing machined for a good fit with an "O" ring, the oil would be forced out the fitting at the bottom of the block where it could be piped to a remotely mounted filter, and returned to the camshaft bushing area through another fitting drilled and tapped into the block about 1.5" above the existing one. : What am I missing?? : Seems like an easy way to get full-flow filtration. : Bob Carabbio I think you have devised a great technique for full-flow filtering!Since you are dumping the oil back into the original oil-flow system with your new fitting in the block, there would be absolutely no difference from the original oiling system as far a flow to the bearings is concerned.I feel it has been proven by many others that the A oil pump is a fine design (really not very different from modern pumps) and fully capable of providing plenty of flow through a filter.Those who have converted engines to pressurized flow to the main and rod bearings have no problem generating "normal" oil pressure with this pump, and since a filter really doesn't provide much resistance, not much pressure is required for normal flow volumes.Your disign does offer some advantages over the valve-chamber mounted filter design (which I have on my A) since there would be practically no way the oil could bypass the filter, as it can in the other set-up if the clearances are excessive in the cam bearing, oil pump housing and distributor driveshaft areas. |
