I'm Diesel Stupid
350k is the avg end of the service life on a IDI. But I've seen many go longer than that and a few die sooner. I pull a 15k GN with my '92 on a commute between Kali and TX. I like the simplicity of mechanicals and the truck has no problems keeping up with others. Also, it's not very stock either. I've also completely rebuilt the powertrain shortly after purchase. I know what I have as a result. honestly, the cost of purchase and refit is equivalent to the cost of a OBS psd. The choice is yours.
Footnote...
I see two posts in the IDI section and one is talking a potential IDI owner out of a purchase and the other has got nuthin' to do with IDI's.......I'm going back to the basement.
Thats good info...I think Im going to look for a 95-97 PSD.
