another take on running in,

http://web.inter.nl.net/users/Rob.Koopman/HTML/rustie02.html

He talks about heat cycling the engine, which makes sense at least with
cast iron cylinders.

 

Yeh, I noticed that too.. it was ok until I posted the link.

 

Makes a change, eh?

 

What do you mean?

Where ever there's shit happening, you're bound to find some muck laying
about near by.

 

Whilst undoubtedly true, I believe that was a minor "whoosh"...

I was just making one of my usual part way through threads random point
ok?

 

He doesn't know how to spell Nikasil, which some people might find
slightly dubios for someone offering unusual advice on running-in
engines.

I think I'd prefer to take the advice of the people that designed and/or
built the particular engine I was running in, over some random unknown
internet bloke. But that's just the sort of wild and crazy guy I am.

 

With every car/bike requiring a run-in and no general crisis of engines
failing left right and centre, it's not something to lose sleep over imho.

I remember a time when you used to see "Running in, please pass" quite
regularly. What happened to that?

Glad to be of service, young master.

If the seal around a piston ring/bore is anything but perfect, you go a bit
smoky and start consuming oil. Fell at the first fence for me.

I have never read such complete and utter bollocks in my life...

the advice given can be summed up thus, "break in" by thrashing the
tits off it, followed by a justification that is clearly intented to
sound all technical and learned, but is in fact a complete crock of
shit of the kind you expect to hear on telly adverts for women's anti
ageing cream.

this moron appears to think the entire break in process consists of
bedding the rings in, while managing to be completely oblivious to ring
rotation in use, and screw the rest of the engine.

this _might_ be some elaborate bonsai kitten style troll, if so it is
in piss poor taste as blown motors can and do kill.

if you want to run a motor in properly the easy way is to limit
throttle travel, on a modern jap superbike limit to say 30% for the
first 100 miles and increase 10% for every 100 miles. Within those
limits you can work the engine as hard as you like and go as fast as it
allows.

the one gem of truth in what that website says is allow you motor and
especially your lube oil to warm up on an IDLING engine, that alone
will save you perhaps as much as 30% of your wear

everything else is utter shite, acidity in lube oil is a result of
metal wear and condensation (water) in the oil, not ring blow by, one
of the reasons certain designs of 2 stroke that use crankcase charging
need more frequent oil changes.

the experienced mechanics / engineers out there take a look at the
three "panorama" pictures of the pistons and see if you can spot the
"significant fact" that job public won't, what is special about those
pictures?
(special in the sense of telly ads, after using product x the person
looks better, because the pictures on the wall are hung straight, the
clothes are the right size and of course you see their face the right
way around instead of mirror imaged which always looks wrong
subconciously.

 

ISTR the gixer was doing 95 at running in revs...

 

Is that all?

To be fair, I think the bloke is mostly talking about 2 strokes. With
those, you have to pin the rings, or they tend to fall out of the ports.
The rest of the engine on a 2 stroke is either on roller or ball
bearings, they don't run it, they just run out.

The control line model plane guys use model diesel engines, that need a
specific running in procedure, which involved heat cycling the cast iron
cylinder, so it attained the correct properties.
