Hi Blokes,
I was visiting a facebook site just recently and came across a wonderful informative piece of technical data that a lot of us may not be up to speed with as yet.
I will relay the information as stated, in the thread that I have just read, it goes something like this:-
Revving the engine to redline makes the pistons go all the way to the top of the engine where if you drive normally they don't wear out the top bit of the bore.
If you drive normally the pistons only go up and down a bit, not all the way, hence no wear on your block.
Since you do most of your driving in the 1500-3000rpm range, it pays to be careful and get that bit working good first up.blah blah blah,
This astounding article was placed on the WA DISCOVERY DEFENDER 4X4 FACEBOOK after being picked up off a Toyota forum or facebook page, it was titled "MUST BE A TOYOTA THING".
I think (or hope) that something got lost in the typing of the thread.
So remember to keep those revs up to redline on start up, you don't want uneven wear in your bore, do you?
Very amusing but scary ehy.

SupporterI think the 'wording' may be the problem.
If a vehicle is driven sedately for years and then over revved there might be a chance that the top ring gets broken on the wear ridge.
I remember a test being done by a motorcycle mag on two identical small bikes in the UK many years ago.
One driven 'normally' the other driven like it was stolen. There was a difference in the wear in the bores where the piston on the bike that was over revved traveled further (by a few thou).

Subscriberthats why cars have a red line, so the piston doesnt come all the way out.

....I can confirm that revving a tired 3.5 to valve float on regular occasions can result in top ring breakage...

Ah. See! If they'd done that from day one that wouldn't have happened. Can't break the rings on the lip if it's not there.

Ash, so I was really lucky when I pulled second instead of fourth in a little Formula Ford several lifetimes ago that the exhaust valves stopped the pistons exiting the bores!!
All four were nicely bent.
