Re: Manual transmission causes crankshaft wear!
You say Heavy clutch pressure. What clutch is causing the problem? Looking at the main bearings in this engine does not seem possible that it would distort. How many so far have had the problem and what are the symptoms?

But when I called an Subaru Expert, he already knew that this was happening. He stated that the wear on the crankshaft journal was dependent on whether it was a push or pull clutch system. The evidence on my (or more correctly, now mine) crankshaft and thrust bearing followed his theory and experience. As to what clutch is causing the problem, it is not brand related as far as I know, (but "We" only use about three different brands) it is more of a the higher clamping pressure, the more damage as collateral damage. So far the best thing to do is to start the engine in neutral! Only start the engine after oil pressure is built I am looking into this but there is a lot going on and will report back as soon as humanly possible.

Re: Manual transmission causes crankshaft wear!
How do you wait for oil pressure to build with out starting the motor. Do we have electric oil pump?

On my only 5 speed, (The Racer) I put it in neutral with the ignition and fuel pump switches turned off, and without pushing the clutch, I spin the engine for about a minute, (best guess) to get the oil pumping, with this 140k mostly stock (temporary) engine, (until I can install the new engine with the Eagle rods and the CP pistons) and after a minute, click on the ignition and fuel pump. It starts and instantly goes up to 80 psi, until it warms up. By the time I install the new engine I will have it figured out. I hope.

Re: Manual transmission causes crankshaft wear!
Hi Tony.
I just got back from a computer-less three day trip to install a water heater at my parents house in Pittsburgh. Yes, THREE DAYS to install an instant on gas water heater replacing the thirty old one that was INCORRECTLY installed. I think by the well known Rube Goldberg! Six.5 hours of travel time, 40 hours of waterboard-eske Home Depot shopping in two nearby cities, one run into a c8urb blowing out my 17" tire on The Claret, three days on ONE SHOWER!!! Four visits to tire and part stores. I'm home now. I will just sit here in the fetal position, rocking, humming to my self, maybe covering up with a blankey... BTW Thank you Brian for the loan of your spare SVX tire, I got home fine! Tony, now, after my rant, I'll go read the E-Mails that you sent. PS. How do you spell "blankie?"

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.

Re: Manual transmission causes crankshaft wear!
There are two switches on the trans. One is the reverse switch which we all use for reverse lights. The second is a neutral indicator for cruise control. It is open in neutral and closed in gear. You must use a relay wired to the 87a terminal to reverse this in order to act as a neutral safety for the starting circuit. Or just hardwire the circuit. Either way you lose cruise control.
