If some dimensions do not match, mark them and send the crankshaft to a machine shop to have it resurfaced. Then measure the crankshaft again so that you can replace the bearings to get the crank to bearing clearance within specification. Step 9: Finish disassembly Remove the core plugs, br...
The timing belt itself is just a few bucks, but if the rubber wears through or a tooth breaks, it'll probably crash at least a couple valves in the engine. See more pictures of engines. Tennen-Gas/Wikimedia Commons Engine timing is critical to the engine's actual function. A properl...
The ECM is a computer, and features many of the same parts as the computer you have at home or at work. There's a microprocessor that receives, interprets and reacts to sensor inputs as fast as they occur. And it's composed of hardware (a pretty standard circuit board) that's encod...
The intake and exhaust steps are combined together, as are the compression and ignition steps. Two-stroke engines are lighter and more powerful; but they aren't as fuel-efficient, they tend to break down more often and they also produce a lot of exhaust gas because oil and fuel mix ...
Positive crankcase ventilation involves recycling these gases through a valve (called, appropriately, the PCV valve) to the intake manifold, where they're pumped back into the cylinders for another shot at combustion. It isn't always desirable to have these gases in the cylinders because they ten...
Some aftermarket devices also let you look very closely at your overall fuel economy, even allowing you to download data and graph your fuel consumption. Others track the data themselves and enter it into their computers, comparing routes to see which way home from work will help them net the...
