I dont remember it staying on that long in the past....Am I crazy and it always did? I "thought" it would shut off almost immediately upon cranking the engine.

It is a red light in the upper left of instrument panel/guages. ]]> 7.3L Power Stroke Engine and Drivetrain jgarden http://www.thedieselstop.com/forums/f24/oil-temp-idiot-light-stays-242605/ http://www.thedieselstop.com/forums/f24/leaking-dahlonega-242602/ Fri, 20 Nov 2009 13:47:53 GMT I need a mechanic in the Dahlonega, Georgia area TODAY.:sick:

I'm visiting here, and when I cranked up this morning, fuel started pouring on the ground at the rear of the engine. It seems to be running into the valley from somewhere. The Filter is not leaking around the top, and the housing is dry as far down as I can reach.

The only dealer I know of is Chestatee Ford, but I don't remember thinking it looked like a truck place.

Any help will be appreciated. Thanks in advance.

The mechanic I had replace the u-joints said there was a little play in the slip yoke (if that's what it's called?) on the shaft.

My question is as the there are 220,000 miles on the rig and I've decided to invest in keeping it for about twice that, should I just get a new/reconditioned shaft rather than paying to have the existing one examined. As the current shaft has a little play in it my thinking is why not just get a new one?

I realize it's possible that the shaft won't cure the problem, but I'd have the piece of mind of knowing I'd upgraded things.

Also as I've made the mistake of buying a cheap hub for the front, is there a "minimum quality" threshold for a new/reconditioned shaft and does anyone have recommendations for where to get one. When I google them I see some reconditioned shafts pop up for about $350.

I have a 2001 F250 4X4 with 213,000 miles on it, engine is completely stock. It is running great, however I have noticed the tranny cannot decide between the top gear and overdrive (shifts back and forth), between 50-55mph or so, the first time I get on the highway and up to speed after the truck is cold. It will go back and forth 4-5 times, and then it is fine the rest of the time you drive it, goes into overdrive when accelerating properly and holds it while cruising no problem. Shifts all feel good and smooth except for this small problem. I have watched the "o/d off" button on the shifter during the hunting, and it is not doing anything funny so I do not think it is the steering column wiring.

So I am curious what direction I should go from here, thanks in advance for any help. I am hoping it will not require a complete transmission teardown!! ]]> 7.3L Power Stroke Engine and Drivetrain Corless116 http://www.thedieselstop.com/forums/f24/transmission-hunting-between-50-55-mph-242586/ http://www.thedieselstop.com/forums/f24/no-start-242584/ Fri, 20 Nov 2009 02:23:18 GMT i have a 94 powerstroke i pulled the hpop off because it kept blowing the oil line and cleaned it up i put it all back together. i primed the oil system and changed the icp sensor but still no start. the codes that came up was p1211,p0340,p0198 if anyone can help please do. i have a 94 powerstroke i pulled the hpop off because it kept blowing the oil line and cleaned it up i put it all back together. i primed the oil system and changed the icp sensor but still no start. the codes that came up was p1211,p0340,p0198 if anyone can help please do. ]]> 7.3L Power Stroke Engine and Drivetrain guthriem http://www.thedieselstop.com/forums/f24/no-start-242584/ http://www.thedieselstop.com/forums/f24/recommended-fuel-saving-chip-242581/ Fri, 20 Nov 2009 02:07:23 GMT I came over from the Non Powerstroke section to ask a ? about my buddys 2000 Powerstroke.I could not give him any advice on this subject because my truck has no computor.He has a nice truck with plenty of power,but would like to rechip to get a little better milage.Thanks for any suggestions about which chip to choose....robert I came over from the Non Powerstroke section to ask a ? about my buddys 2000 Powerstroke.I could not give him any advice on this subject because my truck has no computor.He has a nice truck with plenty of power,but would like to rechip to get a little better milage.Thanks for any suggestions about which chip to choose....robert ]]> 7.3L Power Stroke Engine and Drivetrain robertleo http://www.thedieselstop.com/forums/f24/recommended-fuel-saving-chip-242581/ http://www.thedieselstop.com/forums/f24/expected-life-ball-joints-242574/ Fri, 20 Nov 2009 01:10:16 GMT How long should ball joints last, generally?

My original ones are shot at 82K and I'm sure they've been gone for probably the last 10K. Front tires wore really bad on outside.

Are Ford ball joints any good? Or are they junk? Thinking of having them do them for quote of $750.

My issue... When it is 30+/- degrees outside, My truck won't start right away. Anything higher than say 35...no problems. When it is cold, i will let the GPs heat up for about 30-45 seconds before I start. The truck sounds like it wants to start (maybe 1/2 of a second of starting sound) then nothing. Last week when it was 12 degrees out, it took about 30 minutes of trying before it would finally "take" and stay running. The truck was even plugged in for 3 hours before I tried. I have Diesel Kleen additive (white bottle) in the fuel, and took off the fuel filter on the coldest day, and it was all full and fine (no gel).

Why i don't think it is the batteries... Well, after 30 minutes of trying to start the truck, the starter was still turning over fast and was able to start the truck (no I didn't hold the starter down for 30 minutes...just maybe a 5 seconds every minute or so). The oil level (Rotella 5w-30 syn) is fine (although it is at 5k miles).

What would be the symptoms of a bad/failing GPR or Glow Plugs? I live in Northern Nevada (Fallon) so it doesn't get any colder the 10degrees or so, but it is that cold almost every dawn during the winter...and quite frankly, i dread going out to try to start it when I know it is cold.

I'm going to change the oil to Mobil 1 diesel synthetic (because wally-world no longer carries the Rotella Synthetic...but I doubt that will help much. like I said, it wants to start at EVERY attempt, but never quite goes beyond that original fire. And when she does finally start, white smoke pours out for minutes.
