THIS x's 1000000. I can't wait for warm weather....

 

The reason is as said before: oil pressure.

I'd like to think about it as for the alternator. It can't provide the same voltage thru the whole rpm range, so does the oil pump with pressure.

Anyone can do what thinks is best, I put out my point of view.
In addition to my experience, if you want to thrust, I can't find the right issue but it was well explained inside Race Engine Technology article.
For give you an example, the conclusion for camshaft was that most of the wear on it was generated during idle operation... that is only a small fraction of total time spent by the engine thru the rpm range.

Sorry for my English, hope everyone can understand.

 

Totally agree

 

Right and nobody is disagreeing with you, but to start driving after 15 seconds of startup? That seems a little nuts to me. And I still don't buy that idling is bad for your engine (unless you're somehow overheating at idle...)

 

Idling isn't bad, there are just more efficient and effective ways to warm up an engine.

 

I'm not disagreeing with that. But Fede seemed to indicate that in an earlier post (idling being the worst thing for your car)

 

I warm up my for 10 to 20 seconds every day and my evo x has 72,000 miles and I have not had a problem like yours. But I do live in California its 75-95 degrees for 9 months out of the year. Good luck with your problem

 

You could probably count on one hand the number of people thinking about their WGA spring temperature when driving.

fosty, you operate at a whole other level, man!

Rich

 

Nonsense, you can idle warm up your car. When you crank the motor and start it the engine revs up to around 2k rpm and slowly drops to idle 900rpm over time as it warms up so no oil pressure or other issues are to be worried about. The suspension and transmission will still be cold so I don't recommend going WOT right away.

I said it before, it's the P0420.

 

Where in the manual does it state to wait until one bar is shown before driving? All I can find is where it states to drive the car slowly to allow the drivetrain fluids time to warm up before going ***** to the wall. Can someone provide the page number so I can reference it? In any case, I let it idle for 20 to 30 seconds, then take it easy for atleast 5-10 minutes after the coolant temp has reached its operating temperature.

 

It's not in the manual, you don't have to. You'll be fine if you drive it with out WOT high revs but it's a rule of thumb for turbo cars. Just like people may tell you after hard driving your car to let it idle a minute or two before you shut it off on turbo cars.

 

Hi guys!
I wasn't saying that idling is the worst thing for the car! Going to 7000 rpm with the engine cold is certainly worst than idling!
What I was trying to say is that for engine lubrication, the worst condition is idling. So to warm up the engine sooner and better I suggest to start the car, wait 10-15-30 sec and than drive it with care (avoid high rpm and boost) until 5-8 miles.

 

iirc, it is in the manual. I'll get you guys a page number tonight when I get home if possible

Edit:
Can't seem to find it at the moment, but if I run across it again, I'll be sure to post here.
