oil change after 30 years sitting

Recommended Posts

Fabulous looking G!

How does the oil look on the dipstick?  Any history about the engine?  15-40 diesel engine oil such as Rotella or Mobil Delvac.

Sweet truck. Be sure to document your progress. Hint hint we love pics and a good story about an old Mack.

if it has the period correct luberfinder it likely has to fill up that whole filter assembly  before you start to see any oil pressure. thats how it was on my END711. you might be able to pull the turbo oil feed hose and pressure the block with oil first if you want to play it safe? I think there are some aux ports on the side of the block as well where you could force oil into it?

Had a guy come in to the dealership with just such a truck that was started after decades and was smoking black. I cleaned 30 lbs of mouse nests and droppings out of the air cleaner housing.

Great advice...check all intake pipes and inside the turbo. When I start a truck that's been sitting a long time, I like to pull the valve covers and pour the new oil over the rockers so it runs down over the lifters, crank, etc. Pressurizing the oil passages would be even better.

There's enough mud on that steering tire for 30 years sitting, but that cab looks rust free. Dirt floor barn find? There is no visible rust, must have come from a no humidity state...

Heads up algae grows in diesel, or at least in the new diesel, so you may want to make liberal use of the fuel tank drain and flush the tank out real well. They make a fungicide additive that kills the algae but it doesn't dissolve it. It'll clog things up pretty good. Flush tank, change fuel filters, put some fresh fuel in it and pump new fuel through the system via the (hopefully equipped, but if not it's easy to install) fuel hand primer pump. You'll want to prefill the new fuel filters, and make sure you lubricate the fuel filter orings. And make sure old oring comes off. Never know with a 30 year old sitter.... (2 fuel filters)

Great find. I assume you had it towed out? I assume it's not running yet.

I would change the oil prior to cranking, if at all possible remove the injectors first and spray Kroil,or Thrust, or PB Blaster in each cylinder prior to cranking  do this for a few days to free up the rings . Then crank the engine with the injectors out (no compression) when you have achieved good oil pressure then reinstall the injectors and light it up
