So, after loosing the good fight that I got drug through the mud with for 4 months, I'm left to myself to fix my truck. No other good options. On top of that I'm about to loose my loaner...because I 'should have' fixed it by now even though my rolling junkyard of a loaner truck has spent most of it's time as a dealer decoration.
...and in accordance with my great luck, I found a leaking head gasket and a liner leak on my 871 to go along with the cam I have to fix. No avoiding it now, it needs some work here. Heads gotta come off. You know what that means... 685k miles on it.
I have enough to buy parts and tools. That's it. Fortunately, I'm very mechanically inclined.
I'm finding alot of different part numbers for isx valve cam. 4298626, 4059331, 4298629 to list a few.
I'm finding references stating that the cam from a 2250 fits an 871 and others. I'm having a hard time swallowing that but I might be wrong.
I also know there was a revised camshaft with wider lobes I believe, which would also require a change in rocker arms if I'm not mistaken. A call to Cummins gives me the typical idiotic shrug of a response aside from 'they fixed the cam issue, buy a recon'. Uh, no.
I don't know if these are parts number changes, actual newer compatible revisions or whatever. I know I found an 8629 NIB Cummins cam for $600 but won't buy it unless I know for a fact it'll work right. I don't need to confuse the ECM.
Anyone care to enlighten me? I've got a 2010 cm871. Valve cam is toast, among other things.
