Oil-Pump BlueprintingNever install an oil pump right out of the box. Instead, blueprint and sleep easier. McAfee has a routine he follows, and you're free to follow all or some of it. Whatever you do, verify the condition. Check rotor side clearances, properly index the rotors, and check the relief valve for proper operation. Or order yours from MCE Engines for a precision blueprint.
Stop Leak!Never has there been a better solution to driveway oil spots than the one-piece rear main seal Ford began using in the early '80s. Did you know you can retrofit an older two-piece-seal small-block Ford with a one-piece? Talk with your machine shop about it. All you need is a boring bar and a smart machinist with a nose for Ford part numbers. The savvy machinist uses the boring bar to remove the seal grooves. With the grooves removed, there's room for the one-piece seal.
One-piece seals are not foolproof, however. To be leakproof, they need a thin film of high-temp RTV (gray) around the circumference, then a spot of RTV on each side of the No. 5 main cap mating surfaces, as shown here.
Effective CommunicationFor a successful engine build, there must be concise communication between everyone concerned. When McAfee sends his machine work off to Motor Magic, he attaches a tag with detailed information specifiying what's to be done, right down to dimensions and tolerances. Include a tag with your castings, be sure to get it all in writing on the work order, and keep a copy.
Why Blueprint?If you haven't figured it out already, McAfee is obsessive about blueprinting. Why? Because true blueprinting leaves nothing left to chance. It closely inspects and treats everything to ensure uniformity and proper function. Blueprinting means never losing sleep wondering if you missed anything. So what is blueprinting?
