Here is the scoop on your 2000 power steering. (assuming you have the 4.7L 4.7L V8 "semi-hemi" engine)
 
For model-year 2000 the Dakota got a brand-new front end design. It replaced the old steering-box-with a rack-n-pinion. The 4.7L V8 "semi-hemi" engine also had a brand-new design PS pump.
 
For model-year 2001, the specified fluid for this system changed to SYNTHETIC PS fluid. I suspect that Dodge discovered that "normal" PS fluid was not sufficent. Dodge changed the spec for the 2001 Daks to be ATF+4 (synthetic ATF fluid)
 
Personally, in my 2000, my steering was VERY stiff anytime the ambient temparture was below minus 5F. I tried several different PS fluids and most of them were troublesome.
 
I now run "RedLine power steering fluid" which is 100% PAO esters. (the very best synthetic lube that man can make) Since switching, I have NEVER had any issues with stiff steering no matter what the ambient temparture is.

THe 4.7L V8 semi-hemi engine has proven itself to be VERY reliable. (There are very few other engines on the road that use a girdle made of special iron for the bottom end or MAGNESIUM valvecovers.)
 
What do you mean when you say you have "zero compression".... did you actually check the compression with a compression tester and ALL eight cylinders read zero? I simply cannot beleive it.
 
When was the last time you cleaned your IAC and checked your TPS? (I clean my IAC at least once a year.)
 
Also, a PCV valve stuck open would cause the symptoms you describe
 
definitions;
IAC = Idle Air Controller
TPS = Throttle Position Sensor
PCV = Positive Crankcase Ventalation

#99 of 465 1999 dakota knocking in oil pan by dallase

Feb 17, 2007 (8:58 pm)

this engine is really pretty strong and carries good oil pressure it runs cool just has that knock when it warms up, the truck has had a new distributer put in at 35,000 and a new catalytic converter (excuse spelling)at about 40,000 mi.

#100 of 465 Serious loss of MPG! 98 dakota 5.2 man 4x4 by bthev

Feb 18, 2007 (7:11 pm)

I've got a major loss of MPG(8-15) and it's getting worse! Problem was first noticed after a coolant change, oil change, and belt replacement at a shop. The belt was replaced to bypass the failing compressor. Also I went with a high mileage oil this time (117000 miles). Took it to a different shop and they didn't find any codes, they also did a fuel injector test...all OK. Replaced PCV, plugs, wires, rotor and cap. There is also a noticable ticking sound coming from the engine. Clutch also needs to be replaced but I haven't noticed any major slipping. I also hear a whining noise behind my drivers seat, not like wind, but like rubber or gears. Tires OK.
 
Here are my thoughts:
1. Problems with valves and lifters
2. Exhaust leaks
3. Computer needs an update
4. Compressor actually improves engine performance
5. More transmission problems than I realize
 
Any thoughts on this would be appreciated!
 
SPECIAL NOTE: I have been using Bosch Platinum plugs before and after the MPG problem..they work fine. The split type give better economy and the single type more power.

#101 of 465 Spark Plug and Auto trans question by gtownguy

Feb 28, 2007 (2:01 pm)

Hi guys, its been awhile, i have had a lot going on. Anyways, I have a 01 QC 4.7 auto 4x4 with 77k miles. I was going to change spark plugs again with the stock champions but was wondering if any great successes with a longer lasting platinum type????
  Also, I was going to change my trany fluid. Done this before on other trucks, but I understand my auto trans has a spin on filter inside. Any special tools needed or tricks to know?? Any help and comments appreciated.
 
Thanks,
Tom.

A lot of folks are running Bosch Platinum +4 (#4418)in the 4.7L semi-hemi engine.
 
As for your xmission - I special-ordered he manual xmission myself. I do know that if you do not use the proper ATF+4 (synthetic) fluid in the automatic, you would be asking for troubles.

the best plugs to run beleive it or not are the cheapest,they are also a cooler running plug. Auto Lite 3923, you can pick them up at wal-mart for 10 bucks for all 8. Plugs with plat. tips will detonate and cause problems.
