Re: Manual transmission causes crankshaft wear!
Haven't been here for a while, but just saw this thread. i have some information about this issue which severely affected the first engine on my 94 emerald pearl. Engine was only slightly modified, Lan chip, exhaust camshaft substituted for intake camshaft, Snorkus. It had a 2004 WRX 5-speed, with ACT clutch kit and heavy duty pressure plate. By the end of its life, maybe 20,000 miles and 25 track days, with the 5-speed, and 105,000 miles overall, it had serious thrust bearing wear. To the extent that I was routinely throwing belts, and even had the timing belt slip a tooth. Young Tom can vouch for this. He autopsied the engine, after it fried as a result of a burst coolant connector hose across the top of the block.
Of course, later, with a new block and crankshaft, he built the famous 246 WHP NA engine, along with other mods that ultimately made it car of the week on Bringatrailer and got it featured in the Drive Channel weekly chat show. With that engine, on his advice, I always started it in neutral, and, and at stop lights put it into neutral, totally minimizing the time with the clutch pedal down. My experience is that this is really a thing.
