    Default "free" 599

    Last week i got a free 599 block 6.5 for asking about it laying by the dumpster
    My summers priority has been cleaning out my back yard which used to be the parts yard when i had a mechanic and apprentice working in the shop.Since i have closed the shop and don't have anyone working for me,plus there will be a fee charged before long to dump vehicles at the dump.
    So i set a target goal of ridding myself of 22 vehicles in 2022,#19 is on the hoist.I think i will blow by 22 and end up in the thirties.
    So i decided that i should try and salvage what i could from the 599 block as a change of pace this weekend.
    Was told it was running good when removed,clear water was leaking out as i winched it out of the dirt and onto my rollback.
    I didn't hold out much hope for a good engine,but hopefully a crack free block and maybe a decent crank,besides the injection system.
    The injection system was full of diesel so that was a good sign,no lines got damaged getting it on my deck in a hurry,the guy was locking up.
    A few pic's of what i found.599 b.jpg599c.jpg599d.jpg599.jpg

    The chafed oil cooler line may tell the story. It certainly didn't "run" with that.

    Haven't made it to the getting the crank out yet...
    A few pictures of what i found once the heads were off
    Will try to free up the pistons somehow to lessen the chances of hurting the crank if it hasn't been run out of oil from the oil line.
    Used a zip wheel to knock off the heavy rust then a wire wheel,with some rust killer sprayed in the holes.

    A little Orange for sure......DEEP CREEP PENETRANT WILL HELP....

    THEN.... AFTER SOAKING FOR A WEEK....A good solid block of wood and a 5 pound hammer to try and jar the slugs loose...

    Definitely be a .030" overbore or more depending...

    On a positive note, you have at least $100-$200 of good useable parts. The plenums, serpentine set, ip, exhaust manifolds, etc.

    Yes the positive note...
    Complete fuel injection system with a 4911 pump
    One head with no visible cracks,complete set of precups with no cracks,and exhaust manifolds.No serpentine stuff or top plenum.
    And hopefully a good crank and rods.
    I expected some backlash with my rust removal method with the zip wheel.
    I kept one picture out of the thread but here it is.
    The block is toast.
    The rust probably toasted it as well,not sure if it could have been sleeved for deep rust pits...
    But i doubt it can be sleeved599 bugger 2.jpg for cylinder wall punchout.
    My luck,finally get a 599 block and it's worse than the cracked blocks i already have.
    I plan on a trip to a buddies wrecking yard to see what is laying around there for 6.5 stuff to try and save.

    Does that crack extend all the way from one of the webs? I bet it was from a toasted Harmonic Balancer?

    I wouldn't take that bet. Those cracks, if they are cracks, happened long after it quit running. Robyn likely has it right. This was a block, on the ground, in Alaska, full of water, for years. The climate killed it. There's probably not a single crack in any of the webs. Go figure, but that's how luck runs and, what may have been a fine specimen was claimed by nature.

    Harmonic balancer is in OK condition.
    I think a cylinder full of water and freezing took it out.
    Hopefully the hole in the oil line dosn't lead to a buggered crank.
    I will be pulling the 94 in the back yard before winter to see if there is anything salvageable from it.I was looking at it for parts in the spring for the Burb,but found water in it at the time.
