2000 LX470. 270,000ish miles.
I bought it three years ago with 180k for $8000.

My son has taken this truck two states away to college. It’s seized up on him the other day and we had it towed to a shop. Today the shop reports that the engine is completely seized up and digging deep enough to find out why would probably cost more than a new motor. I have replace the timing belt once, probably just under 90,000 miles ago. They say that doing a timing kit on it may or may not work and there’s no way to tell.

The shop has found a used motor with 135k miles and can get that motor for $1800. It’s from a salvage yard and I don’t know the story behind that vehicle. They are quoting roughly 27 hours of labor and some additional for random other parts here and there for a grand total of $6700 to acquire that motor and put it in.

I am a 10 hour drive away and unable to get to that shop. Before spending this much money I’d inda like to have it looked at by a separate shop for a second opinion but they’re just aren’t very many in that small town (Starkville, MS).

I feel like the truck is worth next to nothing without a motor. It’s worth considerably more with the motor and I could easier recoup my cost by putting the motor in and holding onto it for a few more years before selling it. Other than this, it’s a great vehicle and in great shape. New leather on the interior, looks good on the outside, etc. It’s the truck in my avatar

I’m leaning toward paying for that motor and bringing the truck home. The plan was to bring that truck home this summer anyway and let my younger son that’s still at home start driving it and buy my older son newer vehicle to take back to Starkville when he goes back to school.

Anybody have any other thoughts or insight or advice about the situation?
 
Pay for a compression test on the potential, 135K mile engine.
Question I would want answers to:
Is it a 2UZ-FE from a Land Cruiser?
From a Sequoia?
From a Tundra?
Non-VVTi?
At 135K has it already had its first timing belt.

$1800 isn't a bad number for a relatively low mile engine.
 
Talking to my kid a little more this afternoon… he said when he tried to restart it it cranked very slowly. The shop is saying it is completely seized up. Those two statements don’t seem to agree with each other. Is there a scenario where it might crank slowly for a little while and then become completely seized up? Seems to me like it should be one or the other.

I’m leaning toward spending a few hundred to have it towed to a second shop in town for a second opinion. Can’t really deal with it until Monday morning, though since all this went down just before closing time on a Friday.
 
Do not believe the shop. Ask your son to do a video of cranking (check battery voltage first). It may have a boken timing belt. Engines won't seize for nothing. Ask your son to inspect oil and coolant levels.

You do not know the condition of the replacement engine and you may end up in a worst situation than what you are now. Take it slow and take a step at a time. If your son is not mechanically inclined, post a help in the ih8 seeking another member's help to inspect the vehicle. If it is 10 hours, it is most likely 5 hours for me. if it is within about 100 miles, I can go have a look.
 
Sounds like a shop sees an easy mark. Way more info needs to be sussed out here to prove what they diagnosed.

I definitely took that as verified fact.

Although if it IS just a timing belt, is it a great idea to keep turning it over? Seems like that might be a good way to bend some valves...
 
what's tests have they done? have they at-least took the drive belt loose?
 
A totally seized motor usually happens after plenty of warning signs and/or significant abuse or massive oil leak. A 2UZ suddenly starting slow and then "seizing completely" seems... unlikely.

Get a second opinion or better yet, get it back yourself and throw a socket on the crank. Borescopes are cheap now. Not too hard to spend an evening pulling plugs and get some really good pictures/video of the valves/cylinders.
 
Thank you guys! I’m two states away but going to have it towed to a different shop with instructions to dig into the problem deeper.

So they reported it’s completely seized up, and then said it may be fixed w a timing belt job?
Did they charge for that professional diagnosis? Or they had a card reader telling your fortunes?
 
I say go ahead and get the 2nd opinion, don't say anything about being at another shop unless they took it apart. Just have your son tell them it stalled and won't start again let them figure it out and hopefully give you a detailed diagnosis.Two hours is more than enough to find what is wrong with it. The borescope suggestion is very good idea you could look inside the cylinder if the walls are scored.

If it is an engine issue I highly suggest to bring it home and do the work at your time, look up Car-part.com and search for an engine in you area.
I was lucky to find a 2UZ out of a 2002 Tundra with 185k for only $1550 out the door with six months warranty and I did verify the VIN from the vehicle it came out of. Don't rush into anything take your time and don't let the shop rush you into doing any kind of work.

They were using a Magic 8 Ball. :lol:
 
A super rare timing belt/component failure on a 2000 hundy is not supposed to be locking up an engine. Wonder what "seized up" really means?? Won't turn over? Turn over but won't crank? Cranks but won't roll? Trust less than most if the alternative results in much more money to absentee owner.
 
Unlikely timing belt broke. Unless last T-job was a poor one, wherein tech did not replacing parts like idler pulleys' (bearings). Which Dealership tend not too replace them. Even if belt broke, 98% chance engine is fine. Shop can pull RH cam cover (belt) and inspect belt.

If engine is blown. It's more likely from a coolant issue. Further inspection is need, by first looking for clues:

1) Have your son, remove radiator cap to see if any coolant. No coolant (make sure to get pictures), look for signs of dried (pink crusty) coolant, from front to rear of engine.
2) With a fully charged battery. Have him crank engine with oil dipstick removed. While videoing the engine focused on dipstick tube opening (Camera needs to be held stead). Engine with bad cylinder damage (loss of compression), will have a certain squeaky sound and very often be heard even seen coming out of dipstick tube.

3) Use a bore scope to inspect cylinders.

Still uncertain.
4) Compression test. A cold engine compression test. We don't get actual good readings. But we do see a dead cylinder and variation between cylinders.

If replacing engine with used. Run VIN # at carfax and Toyota/Lexus service history. Do your homework. Once engine picked, based on history. Have shop do a borescope inspection before install.



VIN # plate, is on bank 2 head (RH head, PS). If VIN # plate removed, be very suspicious.
