Initial RPM when Starting
Good news folks, Spring has arrived! I have a question for you experienced L owners. I've had my 01 for 6 weeks (1000 miles), and was wondering about the startup RPM. Every time the truck starts (hot or cold) the engine races to at least 2000 RPM. It only does this for a brief second or two, but I can't help but wonder about engine wear prior to adequate oil pressure. Any comments would be appreciated. Thanks, Bob

If you hold the odometer reset button while you turn the truck on and wait for the display to come back on b4 you let go, you can enter debug/diagnostic mode. If you then press the button a few times you will get a digital readout of your tach. A lot of other things you can look at too. My 01 idles at about 650-700rpm.

You better beleive its done on purpose.
Every time you start your engine, no matter how long or short it was off, its like driving 100 miles. Lack of oil pressure, plus engine operation = worn out parts.
How many poeple have worked with generators? I have little experience with them, but I kn ow enough to know that anyone willing to spend $8k on a generator engine is willing enough to spend an extra few hundred bucks for an oil accumilator. Those things have an operating lifespan on several hundred thousand hours when properly taken care of. Part of that is getting the oil pressure up Before the starter is engaged. More sophistated generators have a safety button to push that gets the pressure up before the engine can even crank.
Its the same way with smal aircraft. I have gone to school (and subsequently dropped out) to fly planes. The people that live on a tight budget have these very same pre-lubers' installed on their aircraft. It costs big bucks to rebuild an airplane engine.
Why dont automakers have these things installed on autos? Engines would last longer. Probably 5 times loner. Cound how many times you start your truck everyday. Multiply that by 100. Wear and tear = $$$ for the automakers. They design specific lifespans to each part. The timing chain is a very good example. 60,000 mile suggested change. If it breaks, you are up four letter creek. And certain makes and models require pulling the engine to fix/service. The technololgy is there. Aftermarket companies make gear kits to put inplace of the chain on chevy small blocks (dont know about ford). You never see these things get out of time.
Sorry about the rant.
How wbout you chipped fellows? How does your truck start?
