There shouldn't be any welding involved. The 4.0 is a detuned 4.2 due to fuel injection.

1989 jeep grand wagoneer 360 how do i test bad crankshaft position sensor


double posted, now with 360, 5.9L V8 fact.
great.
and has no such sensor.
its a CARB car
with ICM , spark magic box. , NO ECU /PCM brain in car
there for no CKP sensors.. sorry?

if you dont know what is there, photo it and post it
so others can see what is missing or wrong, from factory day 1 build.

i google for you
rockauto shows no such part in 360
alldata.com same
hell. even the 90s the same.
see it here.
all schematics

if engine wont start. even with test fuel, check spark
see the spark section below, under ignition.

http://oljeep.com/gw/elec/GW_wiring-1990.html

the distributor has cam sensor. not crank.
it called today, CMP, cam sensor
this sensor sends signals to the ICM the ICM then makes spark
buy driving the coil,
the CMP is more like Points, simulation, and lasts near for ever.

the 89 4L has a CKP (crank sensor) and is know to fail on brand new cars. (you need to tune it to make work , back in 88/89) at flywheel.
ask me how in know./././??


360 spark
CMP >>>>> ICM>>>> COIL>>> Dizzy cap>>> spark plugs.
this is the chain of events.
the DIZZY does the ADVANCING with ICM. totally. on this car.

Jeep block casting code 53008403


what are you doing> , buying a bare block?

why not say what is in hand. (fit what? just tranny and mounts or what? , be legal or make EFI happy, or ? all other parts on engine?)

i did a www scan and in 1 second, bam the 4 banger

not the 4 liter.



2.5L gas engine not the diesel of same size.

so...

1984 to 2002 run (all year run lenght) not an answer.



http://en.wikipedia.org/wiki/AMC_straight-4_engine



what does FIT mean.

to the mounts, the transmission, all will

pass smog

be legal, say in CALIF? (strict year codes there.... btw)

make EFI happy (fit)

just the block, short block or just a naked block. you never said./

key fact on bell housing

Instead of the standard AMC bell housing bolt pattern, AMC/Jeep engineers adopted the General Motors small V6 and four-cylinder bolt pattern



short answer, all years fit, the short block.



In 1986 the head went under a minor revision, the head bolts were increased from 7/16 to 1/2 inch.

id bet that be lowest year.



http://www.allpar.com/mopar/amc-25.html



any with 1/2"head bolts





here is a nice page. google hits are free. huh?



http://engineguy.com/jeep-dodge-chrysler/2-5l-1.html?dir=desc&order=name



crank snout?

oil bypass

head bolt sizes

for sure the best answers are at all the top engine builders pages.

never on ebay. avoid them for facts.





you need a 530 block.

shop for that.

Jeep 360 rattle sound at idle in park


it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

Have a 1979 cj7 cant find a flywheel with right bolt pattern the motor is a amc 360 but a flywheel from a 360 has a differnt bolt pattern than mine any help please


are you sure you have an amc 360 and not a 304 and also are you sure the flywheel came from an amc 360 and not a chevy 350? A 350 will bolt directly in place of the 360. You might also try a 350 flywheel.

1989 jeep grand wagoneer--no gas getting to carb.--


That may be right - no gas in the carb is likely a bad fuel pump, or a clogged fuel filter.
