I've done a ton of reading, researching, & talking to others; I haven't seen any thread talk about it in a long time so I would like to hear some updated experience of the reliability with the 465 multifuels & the truck itself. I hear mix results from people, a lot say the engine is reliable and others who say the engine is expected to last only 50,000 miles. My assumption is that these engines only last 50k if you drive them at 2600 RPMs non stop & not caring about your EGTs. My truck have almost 35k miles and so far I've only had to do basic maintenance and fix things that I cause too break, now I finally got my first issue though, I have a small oil leak when the engine warms up, it seems to be around the injector pump (Don't seem like a big deal, gaskets gets old overtime) I typically keep my RPMs around 2200 and at the most 2300, my EGTs is around 900 Unloaded and 1200 at the most with a load. So, let's hear about everyone else experience, how reliable has your truck been & what issues you guys have?
I'm currently debating on going through my whole truck next year and possibly doing an engine swap, a 12 valve cummins comes to mind, but Im a big fan of the multifuels, I would prefer to rebuild an LDS with an HX40 turbo & head studs to help with the head gaskets with its high compression (Im only looking for around 250hp or so, reliability over power) but it's not worth it if the engine life expectancy is only 50,000 miles when a 12 valve can get 500,000 - 1,000,000 miles out of them. As for the rest of the truck, I know everything else is fairly bulletproof if maintained properly, Im not a fan of the spicer 5 speed but I can live with its short overdrive, Im hoping the 395 tires can bring my RPMs to 2,300 at 60mph, and for brakes Im planning on doing disc brakes in the rear.
