I'm guessing that this is used as a utility vehicle and not as a racer of
any sort. With that in mind, I'd go the crate motor route. In the long run,
it will be cheaper and easier, PLUS comes with a warranty.
Just my .02

>> Hi Im new to the group but my truck isnt.I bought it new in 87 and
>> have purchased a 2001 Wrangler which has given me the ability to put
>> the ole dodge back in order again.
>> What Ive got going is 4x4 long bed that has an engine with 210,000
>> miles. No major engine work. The timing chain has never been replaced.
>> no top end or lower rebuilds The fuel injectors where replaced about
>> 5000 miles ago.
>> Symtoms:
>> When you whack the throttle wide open she dies. If you feather the gas
>> pedal you can get the truck up to speed but still have total loss of
>> power. It backfires thru the throttlebody when you accelerate hard
>> also. The exhaust also sounds like it may be backfiring but its hard
>> to tell since the tail pipe is missing. Can't belive it I've never
>> replaced any exhaust components since new and the thing has gone thru
>> wisconsin road salting for almost 15 years!
>> Observations:
>> 1 Full tank of good gas
>> 2 vaccuum pressure is aprox 22 inches of mercury? pretty steady
>> although its only about 20 when idling. gun the engine she slows back
>> down and its about 22 inches again and will hold there.
>> 3 New Plugs plug wires rotor and cap.
>> 4 timing looks ok advances properly but i didnt follow factory
>> guidelines. Put the light on and dialed her in at about 750 RPM.
>> 5 not a bad idle for 210,000 miles farily smooth
>> 6 checked most of the electrical connections reseated them.
>> 7 removed oxegen sensor. looked ok didnt do factory test as
>> outlined in shop manual tan in color no deposits.
>> 8 old plugs showed signs of cold fouling ie light tan in color
>> yet sooty in apperance. no signs of black smoke from the tail pipe
>> like she was burning to rich more like incomplete combustion?
>> 9 didnt check the fuel pressure yet heading out to the garage
>> tonight :-) Cracked open the return fitting to the gas tank at the
>> throttle body gas was pressent.
>> 10 havent noticed the whoosh sound from the gas tank went I open
>> up the cap. Lack of pressure a bad sign?
>> 11 noticed a connection on top of the fuel pump with a little
>> cap that looks like a tire valve stem cap. Well anyway this nipple or
>> whatever was wet but I also noticed this after i over filled the gas
>> tank since the fuel gauge hasnt worked for about the last 100,000
>> miles
>> 12 no signs of oil fouling on plugs. Havnt done a compression
>> test.
>> 13 tappet noise. always had it
>> 14 oil pressure all of a sudden drops then comes back up. Thats
>> what the gauge says. True reading? The service manual talked about a
>> bushing under the oil sending unit that may need to be checked to see
>> if its seated to its proper depth.
>> Am I wasting my time on this tired motor? Jasper engines will retail a
>> motor for $2165.00 Plus my engine Is that a good way to go? Will they
>> discount off this list price or am i better off rebuilding my old
>> motor.? Seems like they have a pretty good warranty. 3 years 75,000
>> miles? Thanks for any help you people can offer. Im love this stupid
>> truck :-|
