D&S Engines has the facility to properly remove, replace and store your vehicle while the engine work is being performed. The old engine is completely disassembled. During this process we take note of any problematic areas in the engine block, crankshaft and cylinder heads. After the engine is completely torn down we use a number of different techniques to clean the engine components of grease, oil and dirt. One of our specialized tools is a large oven, that literally bakes the grease right off the engine block and cylinder heads. After all the parts are cleaned they are carefully inspected for flaws. If the component is damaged we can usually save it with a special repair. If everything looks OK then we move on to the machining process. You might have heard of a process called Magnafluxing. This uses a magnetic field and special powder to check for cracks that are not visible to the naked eye. This process eliminates that risk that time and effort will be spent machining a damaged item. The engine block, cylinder heads, connecting rods and crankshaft usually always need machining. By this process we remove a small amount of material to insure that the engine's clearances will be within tolerance. It is extremely important that the surfaces of the engine block and cylinder head are machined, this is called decking. The process of decking helps to reduce the risk of head gasket failure due to warped or uneven surfaces. Once all the machine work is done. The engine is painted and reassembled. It is very important to check the engines tolerances at this time to insure a long service life out of the engine. When we assemble an engine we use only name brand quality parts. To skimp on a connecting rod bolt or a push rod at this point is a risk that we just won't take. The final step of the engine rebuilding process is the reinstallation of the new powerplant. We take great care in the reinstallation of the engines to insure that we do not damage the car, especially the collector vehicles. In many cases there are auxiliary components that need to be blasted or polished, its the little details that really make an new engine look and run the best that it can. Special Machining There are other automotive components not related to the engine that need special machine work. When replacing a clutch in a manual transmission vehicle it is usually required to machine the flywheel. This process allows for a smooth surface to engage the clutch. Many times this process is ignored and the result is a chattery clutch. There are some European vehicles that do not allow for flywheel resurfacing, check with your service manual before proceeding. D&S Engines can also machine engine accessories that have a tendency to warp or wear. A flat mating surface is essential on an exhaust manifold to eliminate gasket failures and leaks. We can also repair broken studs and cracked flanges. Radiator Repair and Restoration D&S has on location a full radiator restoration shop. If your vehicle is equipped with a repairable radiator we can bring it to like new condition in our shop. New units are used to replace the unrepairable or unrecorable radiators.
