haven't used them but here is their local info, plus their webpage seems not to be working.

IMHO, I'd be leery of a company who claims to be importing used engines from japan.

You need to diagnose your engine more before you come to the conclusion that you have a mechanical failure.

The engine hits a stopping point when we try to hand crank it so it probably means a bent rod right? I dont know what else it could be. Just hits and you hear a huge clunk like metal hitting metal and it wont turn any further in that direction.

My advice is the same as what was given to you in the other thread. Pull the plugs and let everything dry. Check your oil and make sure you don't have a bunch of water in it. If you do then change your oil. When everything is dry, replace your plugs and try again.

A stoppage with the engine hardly means a bent connecting rod. For all you know, that metal sound could be a valve that is stuck or dropped. Have you looked inside the cylinders through the spark plug holes to see if you can see anything in there? Either way, I think you're seriously jumping the gun with a new engine.

Its been drying since last Sunday when it happend with still no luck. Took the plugs out and sucked the water out of the cylinders and let it set for 3 days and tried to start it again with no luck.

Is there any way to drop the oil pan to get a visual? If not, you have to pull it anyway. Take it out, flip it over and see whats going on. I'm thinking you have a bent rod. What about rebuilding the engine you already have?

The only reason you'd need a new motor is if the block cracked. I'll say what I said in the other thread too, get the thing out of your truck and on a stand so you can tear it down and see what happened. It's probably repairable/rebuildable, and you'll save a ton of money and have a brand new engine when you're done. If the block IS damaged, then hie thee to the junkyard and get a new block for a couple hundred bucks, then rebuild that.

Replacing your motor with a used block of unknown provenance is sketchy and asking for trouble. Those JDM motors are a deal for folks who don't have the space or tools or time to fix their own junk and can't afford to pay a mechanic to rebuild. You don't seem to fit that description, so don't be scared of the wrenches.

Seems like the general word here is to diagnose your problem before you fix it. Throwing money on a new engine at this point doesn't make sense.

Btw, ill move your threads to the appropriate generation sub forum where you'll get more help on your engine.

Hey for what its worth I've bought a couple of Japanese spec motors for Hondas and they have all worked out great. After so many miles it costs more in taxes than its worth to keep the car so the car is scrapped and a new one is bought. I would buy one over a junk yard motor because if you get it from a reputable company they will warranty it for a short time.

Time is of essence. Assuming that it was not a salt water flood.

Remove the sparkplugs.

Turn engine over to dry cylinders out.

If there is no lock up or mechanical grinding noise. All is good.

Change oil.

Install new plugs and use plenty of Wd40 On the spark plug boots and coil packs.

Start it up.

If you have no fire or fuel, you will need to remove the ECU, flush it with distilled water, dry and re-install. Try again.

I know about flooding 4runners...

Haha looks like you've been watching too much duck dynasty! You got yourself a nice duck blind started!
