Re: Hmmm..... Cranking engine without firing.....
Hand cranking cannot be compared to a low idle.U cannot cause any problems with a slow hand crank but a low idle start for a fairly dry motor makes thing move to fast but not fast enough for proper oil pressure
and therefore could cause more wear.I think there is a happy medium here.Thats why i believe most vechicles are designed to go into a high idle on cold start up .Porsche really richens up the fuelmixture
on cold start up and therfore want u to get moving rite away but nothing higher than 4000 rpm until temp is at normal .I have tried both ways and if i let the car idle for say 4 or 5 min i find that it will smoke
alot out the tail pipe even thruout the day on warmer starts,just waaay to much fuel.I also think that can contribute to AOS,02 sensor ect issues.I now start and go regardless of temp out and never see smoke
out the tail pipe.The only time i let it idle a little more is if i have been driving it really hard i willl let it idle for a minute or 2 before shutting it down.I find if i just shit shut it down quik after a hard run its hard to start again.
Sorry getting off topic here,just some observations .
