spidermonkey Posted March 9, 2009 Share Posted March 9, 2009 ok so when some one on here says the top end has gone can you explain that to me? is he on about power? throttle or what? He is probably on about something in the head or valvetrain, the top end tends to be the head the bottom end is the block etc Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted March 9, 2009 Share Posted March 9, 2009 The bottom end of any engine consists of everything below the top end.............. Alright only teasing, the bottom end is also known as the short motor, this consists of pistons, rods, crankshaft, bearings, bushings and of course engine block and sump. When refering to the bottom end you're usually talking about anything between the crankshaft and the pistons, problems in this area are known as bottom end problems. The cylinder head of an engine is bolted to the engine block, I've never heard it referred to as the top end but I assume from your question this is what you mean. The term "top end" usually refers to the upper portion of a cars rev range, an example of this would be if someone says "the car is making good power at the top end". The cylinder head allows the engine to inhale air and fuel which is then ignited by the spark plug and then to exhale the exhaust gases. Its all controlled by the timing gear of the engine.
