If you need to ask that you must be clueless as to how a clutch works,
or not thinking before pressing 'Send'...!
If you are causing the release bearing to push against and hold the
clutch diaphragm spring compressed (by depressing the clutch pedal)
the crank will attempt to move way from the clutch cover, this
movement will be within the crankcase and cause the crankshaft to be
forced into heavy contact with crankshaft side thrust (end float
control) bearings - this is why they are fitted, an engine doesn't
need these thrust bearing unless there is a side thrust present. It's
also possible to find the opposite happening if light pressure is
applied to the clutch pedal were the engine has end float issues, you
can find slight up and down movement of the clutch pedal.
Many, of all makes and models, fresh from the factory all should start
with the clutch depressed, 50 / 70k down the road some will still
start OK whilst other won't.
I'm neither clueless nor unthinking. I find it difficult to accept that
the small additional side thrust encountered in the 5(ish) seconds that
it takes to start the engine has a significantly higher effect than the
side thrust encountered during normal running. Let's face it, it takes
hardly any more time to start the car than to change gear - and you do
that far more times than starting up.
By your reckoning my Series 2a Land Rover with 460,000 miles on the
clock should be on its 7th clutch by now, whereas it's actually on its
second. Likewise, all the Discovery's I've owned should have been on
their 2nd or 3rd - but were still running originals at 150k+. Ditto the
current Xantia with 170k+ on its original clutch.
BTW, the Xantia owners handbook says you should depress the clutch
whilst staring the engine (petrol or diesel) in cold weather.
Just as I've never encountered a car exhibiting Jerry's non-starting due
to excessive side thrust I've also never driven a car that MUST have the
pedal depressed to start it. What have I missed out on?
I'm not ignorant at all ... i accept all idea's i know i don't know
everything and never will ,i work as a peugeot master technician..but yours
jerry unfortunately come across as pure bollocks. You may have so many years
experience ..but its obvious you haven't been doing the nitty gritty stuff.
kind regards mark

You're a 'Peugeot master technician' then? That means you see only new
or dealer maintained cars then, perhaps it's you who needs to do some
nitty gritty stuff rather than spout the pure bollocks - if the dealer
doesn't see the faults they can't exist...
I once had an argument with a BMC/BL senior parts manager as he could
not accept that one could have a loose gear on the distributor / oil
pump drive of a Maxi engine - 'cos he had never ever had to supply one
in all his years - until I showed him the faulty one I had on the
bench behind the engine hanging off the crane in front. Or the Ford
dealers workshop manager, in front of engineers from Dagenham, who had
never seen an incorrectly drilled oil-way in a cylinder head before -
even though his workshop staff had fitted three (yes, 3) camshafts to
the same CVH engine in question under warranty - they couldn't
understand why one of the cams failed within a few hundred miles -
quite nice seeing senior Ford Motor Co. management giving a right
bollocking to their dealers rep' in the middle of the workshop of a
small inde garage... :~)
It sounds like the motor trade would be lost without you !. I do nitty gritty
stuff EVERY day of my life so do all other master techs. we don't always
just see dealer cars or dealer maintained ones. we see vehicles from some
independent garages who don't have the knowledge to fix the vehicles (not
their fault). Maxi engine and cvh engine probs wow SO WHAT?? you've spotted
a fault a dealer couldn't ?? don't you think we see things other dealers or
indep. have missed so what ?? its going to happen . Theirs only one ignorant
person in here and im afraid its you .."In 30 years experience i haven't
HEARD OF POST HEATING" . "Real knowledge is to know the extent of ones

Your personal assessments of me have no bearing on this discussion.
Making the statements that I must be clueless, unthinking or ignorant
without any knowledge of me, my qualifications, experience or occupation
speak volumes to everyone else in this newsgroup.
To date, you have not produced one single fact: just anecdotal evidence
from your experience, so here's a challenge for you.
Name me just one car that has an inhibitor on the clutch pedal that
means it won't start without the clutch depressed as a standard fit item
and just one that works the opposite way.
The Renault Megane with the silly keycard thing won't start unless you have
either the clutch or brake pedal depressed.
I had an Alfa once that wouldn't start no matter what you did to the clutch
Pete M - Using the Scouse Side of the Force -
That's it, Pete, go and spoil it for me :-)
Here I am amusing myself baiting Jerry and you go ruin it <BCG>
The Megane is so ugly (at least it's rear end is) they should have put n
inhibitor on it so that it wouldn't start unless you were a registered
scrap merchant. No offence intended if you own and/or like the back end
of the Megane :-)) Can you imagine the read end of the Megane married
to the front end of a Fiat Multipla? Now that would be seriously ugly!
I have found only one. In 1991 I drove a Citroen AX330 (cheaper version of
a 2CV) and it did not start with the clutch depressed due to the side thrust.
I do think its a bit extreme to assume not using the clutch to start a modern
car would be a standard practice though. I dont think it really matters and
its safer to always depress the pedal.
