Leaving Ticking over when cold

[j3gme]

Hi is it proven to do any damage to the engine if say..... on a cold morning you leave your car ticking over to warm up, I know diffs, tyres, brakes, gearbox, etc would not be warm so gently goes when setting off on a journey, but theres nothing in the handbook under "warming up procedure" to say you should'nt do it. Anyone know any diffrent???
Thanks

Personally I can't see any harm will be done I leave mine to warm up if its cold.

Chris,
It depends on the engine. A S6 - not advisable.

I have been told this is a definite no no for a S6 - you should warm it up by drving, but obviously keep the revs way down, until the oil temp is up.

Tickover is not good as the oil isn't being moved around as much as ideal, plus idle speed places to highest loadings on various internals such as the camshaft. Not good. Best to at the very least hold the idle at 1200-1500rpm, or just drive off which is what I recommend.

I agree. Never let the sp6 idle when started from cold, the oil pressure is low so no oil may be getting to the Cam, even with the oil way expansion I had done with the rebuild. It's best to start off immediately and get that oil pressure up. Thats my view.

I always leave mine for 2 mins - on startup I generally (at the mo when its cold) have 60+ on the oil pressure.

Then drive but keeping the revs down till it hits the "GO" temp, then we are off...!

Tend to keep mine at ~1500rpm for a couple of minutes if really cold and then drive off keeping to light throttle and under 2500rpm until warm. Oil was -1C when I took it out of the garage today, drove off when oil was about 5C.

10 secs at 1500rpm, then off we go!

As said, the Speed6 suffers from low oil pressure at idle, so you wont be doing her any favours leaving her idle for long...

[Englishman]

Do your really mean low oil pressure? Mine is up to 70psi at idle when cold. But I agree there is probably little oil flow to the top of the engine when cold and idling so best to get going.

[Targarama]

Yes, sorry, I mean oil flow.

Always did the same - a few seconds at 1500RPM or so till everything's flowing and to stop it stalling on a cold morning, then off at low revs.

If lack of flow rather than pressure is the cause of excessive wear wouldn't an uprated pump cure the problem assuming such an item was available?
