motor loads when clutch pedal pressed

This is something new, that I haven't seen before... The engine becomes loaded, like you just turned on 8 head lamps, when you press the clutch pedal down... Doesn't do it when the engines cold, but the warmer the engine is, the worse it gets... I had to raise the idle or it would die when you press the clutch pedal down... I'm thinking/hopeing throw out bering, and not some motor issue, makes no audible noises either... I'm baffled

Re: motor loads when clutch pedal pressed

Does it try and creep foreward if it's in gear, clutch in, and no brake?

Re: motor loads when clutch pedal pressed

I think Shane's right. Have someone push on the clutch pedal while you look down the timing belt side at the harmonic balancer. You'll be able to see the pulley move in and out.

Re: motor loads when clutch pedal pressed

thats what I was afraid of... but my crank should be fine, its just the thrust bering that must be worn out then. unlike the 2g's that have bad cranks

Re: motor loads when clutch pedal pressed

yep.... its walking... dunno what the end play limit is, I'm guessing a good .020" or more when you press the clutch...

Re: motor loads when clutch pedal pressed

seen that also it happed to one of craigs blocks and cranks,because crank shaft supply was to polish the crank and they cut it and did not tell us. the crank destroyed the block and oil pump in a month. they ended up buying a new mistu block and crank for us for there fuck up

Re: motor loads when clutch pedal pressed

well 6 bolt motor guys should take note... you are not immune to crank walk. I didn't bother to measure the walk in this but its at least .020"

If you build it right there's very little chance.
