3.2 Warm up or drive off

[albroon]

Recently there was an article in 911 & Porsche World which suggested that one should warm the engine through before driving off in a 3.2L

The owners manual suggests that you should not do this!

I'm confused.

With the 3.2L engine's reputation for eating valve guides, I'm also concerned.

Which policy should I follow?

Follow the owners manual.

Keep the RPM's below 3000 until the oil temp. reaches the 1st notch on the guage.

Beware the urban myths!

The owners manual is right. Around a minute of idling at most, then keep the revs below 3 - 4K until you see 180 on the oil temp gauge. NEVER lug the engine [low revs/high load] - always a glden rule but especially when cold.

The valve guides? Mine were in great shape at 150,000 miles. High oil consumption can be symptomatic of several issues, only one of which is valve guides. There was a bad valve guide materials choice during the 3.2 production run, but most of these failed before 50,000 miles.

Drive it hard, change the oil regularly, and enjoy the ride!

I get into my car, start it, and drive away. I keep revs under 3500 and above 2000 (the manual indicates to not "lug" the motor). I don't warm it up for a minute.

Follow the instructions above. One things people forget when they let their cars warm up in their drive way, is that the transmission oil is still cold.

a little knowledge can be dangerous

i struggle with this one. my head tells me to warm up first, but i go with the manual........ditto above, just drive carefully for ten mins.

Forgive me for agreeing with 911 & Porsche World, but if you don't let the Carrera go through the warm-up ritual (fast-idle) governed by the DME, it has a tendency to sort of choke and want to stall at low RPMs, forcing you to give it more gas and inevitably pushing it over 3000 (which seems to clear-up the problem). I've been told this is a characteristic common to all 911s and a mechanism built into the design. Shifting is also much harder, particularly with the 915, when you drive off cold. I've tried both methods, and a reasonable warm-up period seems a lot easier on the car. Ok, now you guys can blast me

I let my 85 run for about 30 secs to get the oil circulated and under pressure and then drive off...no prob keeping revs at 3K or less until warmed up. Shifts a little more tightly for a few blocks but thats fine.

By the time you get the seat belt fastened and get situated in the car after starting it, its ready to roll. No reason to sit longer and waste fuel, you started the car to go somewhere.
