Start n Stop driving.....
I am just wondering because I just talked to a man with a PS 7.3 who bought it new in 1996 and had like 300 thousand miles on it with a lot of start and stop driving and he told me every year it needs a starter and batteries to keep it right.
I thought it was only the IDI's, by the way I love the diesels but gassers do not eat these items like this....
He was in the market for a new truck and said it would be gas...... He no longer pulls however and cannot afford the new diesels.
My mom's got an '02 with 380K miles on it so far(had like 10K when bought in '03), and it's gone through perhaps 2 starters and 3-4 alternators in that time. Probably 2-3 sets of batteries.
Now, this truck's driving patterns were different than that - for most of it's life, each trip was 60-ish miles one way, and it was a daily driver. Some heavy hauling, but not much comparatively.
Of course, I've noticed the same thing with my IDIs - I haven't gone through /nearly/ that many starters; I have ended up pulling the starter every year or two, to either clean it or replace it.
Most of the time, if it starts cranking poorly, it's either the batteries are failing or the starter has gunked up... NOT failed. Of course, my time-to-maintaince ratio may be different due to using used starters - I haven't actually bought a new starter yet. It's always been one that I either got cheap/free or came with a vehicle.
I've also reconditioned at least one starter myself by installing a new set of brushes and greasing it.
Usually, though, it's just a matter of crud from the engine getting inside the starter and it needing to be cleaned and greased.
edit:
Note that for the last couple of years, I've been commuting 10 miles to and from work each day with my IDI. 8 miles of highway, just about enough to get it fully warmed up before I shut it off.
I haven't had any issues with running the batteries down doing this; 10 miles seems to be plenty to keep things charged when starting from a mostly-charged state.
My mechanic set me straight on rebuilt starters and he was like in most cases there is no substitute for new.... Both of mine he looked at to try and make one good one did not pass the test. The armatures were to worn to bother, he said even a little to much blueing on them they are ready for the trash.....
I have a 3 miles commute and do about 4-6 starts a day. Starter didn't look anywhere near new on the truck when I got it lasted 3 years with junk batteries and crappy cables. New 2/0 and 3/0 cables and group 31s and a Powermaster starter later when the starter gave up it's last... Time will tell how long it lasts but I expect it'll last a very long time. When it fails I'll report in here with the postmortem, which I suspect will be whenever the brushes wear out that'll be all it needs.
If your engine does not start quickly, fix that and your starter will thank you with a very long service life. Long or repeated cranking sessions will significantly shorten the lifespan and increase risk of overheating or damaging the commutator bars or windings rather than just replacing brushes and blowing out the old junk.
As for comparing to a gas truck. I daily drove my 460 truck very similarly to how I drive the IDI for 7 years before I got the IDI. It went through one starter, and that was actually a failure of the wee little 4ga cable, it burned at the end on the solenoid. Replaced solenoid and ran new 2ga cable and it started like new. My fault for not looking things over often enough before it got to a no start, but easy enough to see what's wrong and push start. It's easy to get lax on maintenance when you have a simple reliable vehicle that just plain works every time.
As for carbureted gas vs IDI diesel reliability I see little difference. Maybe slight favor in my experience to gas engines as I've had issues with return caps leaking air causing the occasional hard start. It's an inconvenience of the return system design but the engine will always start and it's a fairly quick fix to identify the wet cap and replace o-rings. Not a show stopper, tends to only happen if I've done anything up top recently and bumped a return cap. Aside from that my stuff just plain works be it gas or diesel.
I will say I own nothing EFI, tried that once and it was the most unreliable and annoying POS between the electronics not wanting to start in cold weather (needed gas or starting fluid in the intake, then was fine the rest of the day), and the driveability issues from emissions equipment that was a never ending time and money pit that never ran quite right as compared to a carbureted engine. Never again with EFI.
In the winter time (temps in the single digits or lower consistently) I will throw a charger on the batteries about once a month just for maintenance although it is probably not needed.
There is no doubt the newer diesels make more power but they have more to deal with.... Definitely for High way use pulling an IDI needs a turbo.....
