MY VOODOO IS USING OIL !

[jasonstang]

Interesting point about warmup. I basically live in a desert so it is quite chilly first thing in the morning. I let my car warm up until i hear the rpm idle drop which usually takes about 3 or 4 minutes. I drive it quite gently until the oil is up to temperature which usually takes another 10 minutes.I drive my car pretty much every day and follow the same routine.I am in BC so we have some spectacular driving roads in my area that I can really drive this car quite aggressively on however I am always cautious to make sure my temps are up prior to doing so.

That's usually the best way to warm up the engine.
It also keeps less fuel out of the oil as well as heating catalytic convertor faster.

So let it warm up a bit or jump in and drive right away?

I would not let the car idle for any longer than it takes to adjust your seatbelt. Driving at low RPM (2-3k) is better than idling.

Usually just wait till CHT hit 120-130F (or rpm drops to 1000 ish) and you can start driving. Keep the rpm below 3000 and loud pedal no more than half.
I've never had any of my vehicles idled to operating temperature since new and none of them burn any oil.

The best way to warm up the engine is driving the car. Idling for extended time periods is the best way to glaze the cylinder walls and mess up the ring seal.

From the PCNA manual (the only one I have in PDF handy; emphasis mine):

Starting the engine

• Turn ignition key to ignition lock position 2.
• As soon as the engine starts, release the ignition key.

The first operation of the starter is ended automatically when the engine starts.
If the engine does not start, subsequent starter operations will not be ended automatically.

If the engine fails to start after 10 or 15 seconds of cranking:

• Wait about 10 seconds before engaging the starter again.
• When starting the engine, be ready to drive immediately.

Drive vehicle at moderate speeds and avoid engine speeds above 4,200 rpm during the first 5 minutes.

• Do not let the engine idle to warm up.

After several tests the dealer has determined that my engine needs valve seals in two cylinders. Glad its not a problem in the bottom end!!

ouch, good luck!

No NOT rev it high or go WOT until the oil temp is >140*F.

I always drive gently until its warm. It has been using oil since day 1

how did you break in your car? every V8 I have owned and known has this issue and it usually comes to breaking in the engine.

If you babied it, you are SOL. If you varied gears and rpms and redlined it several times, you ensure proper piston seals.

The owners manual says not to idle to warm up the engine

In this case I read the manual and followed it.There are varying opinions on how to break in and engine.I have always done a hard break in on previous engines and never had an oil burner.For the first hundred miles the manual recommended varying rpms which is what i would expect and no "extended" WOT use.They did not say to keep it under a certain rpm as some manuals tend to do. I have the feeling these engines have probably been spun and tested and properly seated right out of the factory. If this wasnt the case then the three or four people who handle your car in transport could be determining how well your initial break in goes. My car had ten miles on it new so who knows??

Don't forget that we've got twice the number of valves as most V8s, which doubles the chances of a bad guide/seal to allow oil in the combustion chamber from that pathway. Not that this is even a problem, but it seems that rings are the only discussion item when we talk about oil consumption in the Voodoos.

MAV basically nailed it. The dealer did a compression/pressure test and all cylinders were perfect and even.Two valve seals on order from ford to fix the oil burning issue.

Pardon my mechanical ignorance but how did they narrow it down to the two valves if the compression was OK?

Thanks for keep us posted SMS.
