yes, it is.... it can be trashed... but anything "timin'" comes from ecm..................
if its tha same hole that keeps goin' down there are several things that can cause it......... what was tha first fix... how long did it run on tha first fix?
if either crank and/or flywheel splines are screwed then ya may need ta replace at least one or tha other or both............. on a bad part is i've never heard of either one being able ta be fixed... tha hub on tha flywheel can be replaced but would be more cost effective ta jus replace tha...
no key at all.. tha flywheel will only go on one way.. it fills tha gap ya referin' to........... it can't "snap" off... flywheel splines match tha crank.
2000 + have whats called CDM electrics or also refered to as "electronic motors".. they have a single control module that controls/does justa 'bout everything 'lectric on that motor... so no you can't.. it doesn't have one individual advance/idle stab. module
jus know tha V6 stuff... a little pre (inline 6's) V6 era... oiler was form "83/'84, can't remember for sure exactly when tha oiler came out on tha V6, tha design stayed basically tha same for 20+ years...
one thing is certain, tha ONLY ones ya hear 'bout are tha ones that take a dump... you...
you and me both............. it is convenient for most though.. i've never kept it on anything i had but most of my stuff i twisted way up on tha rpm scale... good luck and hope ya solve this little inconvenience..............
do you know tha history of tha motor?.. reason i asked is if its ever been over heated either one or two times being major or if its been over heated several times being minor ya might consider an oiler delete....... any type of heat weakens tha ring gear on tha crank...
best i remember its B.. continuity will tell ya... no readings involved, jus make or break... if it doesn't do that its bad... sounds like it may have a "sticky" spot in tha travel somewhere...
forgot... you can test tha contacts in tha cap with a continuity test.. connect leads to tha blue and black then move tha float up and down tha shaft... should make and break tha reading.............. make sure tha float moves freely on its own and doesn't stick anywhere....
there are only two sensors that will trigger an oiler alarm when all is workin' as it should, low oil in motor tank and rotation sensor (this one is kinda iffy sometimes)
does tha motor tank stay full (or close to it) on its own?.. if it does ya may have a faulty contact in tha cap.. when you...
since you have no "history" about this motor then i would also recommend gettin' rid of tha oiler... not knowin' about whether or not its ever been hot or not over tha years is not a good thing....... jmo
history of a motor is very important ta know... ya mostly can't go with "tha seller says"...
to old and forgetful ta argue 'bout it... could be but think tha '84 had a three ram also.. maybe not all but those were some transition years ('83/'84) with trim, block design, chargin' stuff, mounts and such... most internet parts list are no help with pining down what went where and when...
