Pop the hood off when you go to put it back in?
4 bolts? Get it out of the way?

I actually had plenty of space to take it out with the hood dampers off and tilted back nearly vertical.

Got the engine over to the machine shop today. I probably got 5gals of cream filling from the block and oil pan. Other than being a chocolate eclair of an engine, it's in decent shape. Headgaskets didn't blow, rods don't seem bent, if the crank and bearings look good then I'll consider myself lucky.

Everything is surprisingly intact.

No rods were bent and no bearings were in bad sbape

The sludge made it inside of every journal.

One tiny line around the crank that will probably polish out.

This bolt was seized af and ended up snapping the timing cover trying to get it off.

Lifters, cam, and balancer out and in the wash.

Cylinders are all smooth

Same for this side

Never ending milkshake

The machinist is backed up right now so I went over and tore down the block to save some time and money. Pretty straight forward. Everything will get inspected and new parts should be in by Friday.

​Deck the block, surface the heads, bore the pistons, replace bearings, seals, gaskets, freeze plugs, pistons/rings, timing chain, tensioner, oil pump, and anything else I can.

It just keeps splooging everywhere, hopefully that's the last of it.

Do you have the capability of hot tank and magnaflux? It would suck to get it all machined and rebuilt only to find out you got a crack somewhere

mbb has a good point. You haven't found the source of the leak yet. You had a decent picture of one half of the intake manifold sealing surface. Hope you inspected it before cleaning, and found something.

Have you considered just getting an engine from a salvage yard? If you find a truck that has been wreaked but otherwise looks in good shape and you can't see anything wrong with the motor, you could probably buy it for $1,000 or maybe less. If it is a good motor and you continue to take care of it, it should last as long as you will own your truck. I have known a lot of guys who have replaced motors with salvage yard motors and had good success with them. This will probable cost you less than rebuilding this motor and you will get back on the road faster. Also, with all the damage done to this motor from the water you could have damage to your crank shaft, cams, cylinder walls, and the numerous other parts on the motor. If you should have a cracked block that you didn't find when you do the rebuild, you could end up having a big problem with your rebuild. With all the risks involved with this truck, I would try to get it running again with as low a cost as possible that is why I am recommending a used salvage yard motor. because I think it has the lowest cost and the lowest risk of failing you and all your efforts of getting your truck back to a reliable vehicle.
