Best engine Rebuild kit for a 3urfe

I have 2013 5.7 with 320k miles on it.

I want to have it rebuilt if that's possible. there are full kits online prices ranging from 600 to 1200 complete with pistons, rings and bearings gaskets, etc.

will the block hold up?
is it worth rebuilding?

Any advice or thoughts on the subject will be appreciated.

 

Is there is a loss of compression?

Is here oil loss due to blow by of the rings and or valve train?

Is there oil in the water or water in the oil telling of a blown head gasket?

Has performance dropped off?

If no leave it alone and drive it.

 

Oh, this engine is shot, it has been removed from the frame and is sitting on the floor taking up space.
My tundra is running well with the 4.6 swap that I documented in a thread on this site . I figure it will be easier to sell with the original engine here in California.

The old engine would crank but wouldn’t start, if you cranked it enough, water would flow out of the tail pipe.
There was no oil and water in the radiator or under the oil cap.
I had an engine waiting for her when I bought it.

update on: 5.7 to 4.6 swap- The 4.6 is running strong, traction control lights are on but no check engine. Once in a while, we the truck is left Idling it will start blowing white smoke from tail pipe, I am assuming it’s because I left the air pumps disconnected.

 

Sorry it's currently out of stock... https://www.pureperformancemotorsport.com/toyota-3ur-fe-7-0l-stroker-race-engine.html but it's also in AUD so you'll save another $13k there.

On a serious note you're probably not going to find many with 5.7 stock rebuild kit stories. Most would either take it to a dealer, or swing in a used running engine. Looks to be about $5k currently for a decent used 3UR-FE. Compare with parts and labor for a rebuild.

 

Are you trying to sell a 320K Tundra with a scrap engine?...Or, planning to rebuild the scrap engine for sale?

If you're trying to sell a 320K mile Tundra with a blown engine, replace the engine as cheaply as possible; i.e. used engine. Customers buying in that market segment will not be checking to see if the Tundra has "matching numbers". A used lower-mileage replacement will make the truck more attractive, rather than less.

You will have to consider the cost of replacing the engine versus simply parting out the rest of the truck to determine which nets you the most cash.

Even if you provide the rebuild labor, it is unlikely that you will be able to simply replace parts at 320K miles. You will likely require expensive machine work to heads and block, maybe enough wear in the cylinder bores to require oversized pistons. Anything less than what is needed risks throwing a fair amount of money into a rat-hole for little gain.
