Chapter 1 General Engine Installation & Break-In Highlights RND Engines have been carefully remanufactured to precision standards. The engine will perform properly if both the technician carrying out the installation and the vehicle owner follow the guidelines provided in this directive. If the engine installer or vehicle owner does not follow these directives, has poor situational awareness, or executes poor judgment, the engine can suffer damage or premature failure that may exclude it from being covered under warranty. When in doubt, direct all questions and comments in writing to [email protected]. The following is a partial list of causes for a remanufactured engine to fail early in service. When a properly remanufactured engine fails to give satisfactory service, it is usually due to: damage to pistons caused by detonation, pre-ignition or “lugging”; piston scuffing or seizing usually caused by overheating or excess fuel; bearing and crankshaft wear caused by under-lubrication, contaminants in the oil such as dirt, or coolant seepage; excessive piston and cylinder wear caused by ineffective air filtering, coolant seepage, or (most commonly) excessively rich air-fuel ratio. The leading cause for issues related to engine break–in for engines equipped with NSC-plated cylinders is from over-enrichment of the fuel system. Engines that “run rich” will wash down cylinder bores and never achieve ring seal. Vehicles with original equipment core engines that have suffered previously scored cylinders are especially susceptible to over-enrichment concerns. We have seen remanufactured engines suffer failures due to enrichment issues at start-up and during break-in from faulty injectors or other issues resulting in incorrect fuel trims. As a result, RND Engines mandates that NEW GENUINE PORSCHE OR NEW GENUINE BOSCH FUEL INJECTORS be fitted to all engines under all circumstances. “Cleaned” fuel injectors will not be acceptable. ENGINES THAT HAVE NOT BEEN OUTFITTED WITH NEW FUEL INJECTORS AT THE TIME OF INSTALLATION WILL IMMEDIATELY HAVE THEIR WARRANTY VOIDED! NO EXCEPTIONS! Genuine Porsche or OEM components are required. USE OF SUBSTANDARD AFTERMARKET OR PERFORMANCE COMPONENTS ARE NOT AUTHORIZED. For example, use of incorrectly oiled reusable air filters may foul MAF sensors, aftermarket exhaust or sport catalysts may cause rich running, and aftermarket ECU tuning may raise or eliminate safety limitations such as rev limiters and monitors that may prevent a check engine light from coming on due to incorrect engine operation. Use of ANY of these types of components will immediately void the engine warranty.
