Would you do a Major engine overhaul with parts quality these days?

I would do a rebuild myself but wouldn't trust a shop to do all the superfluous checking and measuring you have to do to ensure things are right.

 

[KrustyTJ]

If he’s not sure on keeping it my vote is junkyard engine with warranty been there done that it worked out well

 

[arse_sidewards]

An RV would be the LAST place I would look for an engine.

Disagree. Roof goes before engine. You can pick up a shitpile with a 60k engine that might have another 60k of RV use on it and get 200k out of it by swapping it over to daily driver usage.

 

[Mikenike]

Nothing, it sits. When it started missing he went and bought a 2018 F150.

He is not sure what he wants to do with it. Fix and sell, Fix and keep. He is hung up on building it, or cashing out.

Either way, non running was not worth anything so something had to be done.

In that case junkyard engine would be my vote

v10 has a lotta bits inside it
I don't even like 6cyl stuff because it has too many things in it


so....
get a 4-53t to use instead

Ha, put one of those in a GMC pickup in like '84, 5 speed behind it. Top speed 60 mph, but it would pull 14K while doing it.

Built a 5.0 sbf this past winter/spring.

So far so good, but we are barely past the break in stage

 

[Kyle]

Depends on the cost.

Made in China parts are trash.

 

[TrikeKid]

I'd buy the reman with the best warranty, usually dealer or Jasper depends on the application.

 

[Lumberjack]

I would rebuild it, great learning experience for both of you.

 

[fordguy]

how much is youe time worth? good machine shops are HARD to find

good tools are EXPENSIVE

parts quality SUCKS

those v10s hard to find in so-cal tho...

hard choice honestly.

I'd bet most of them up here get tossed in the aluminum breakage bin rather than being put on car-part, because people leave bad reviews when they get an engine that has several broken off exhaust manifold bolts, and every single one up here is going to have a few broke off studs

like a bunch if other useful rare parts, stock or aftermarket.

If you rebuild it with normal off the shelf parts, do you think that a rebuilder would use anything better than that ? Even a cheepie rebuild lasts pretty good in my experience. If it’s not destroyed then rings and bearings and a timing set will last a long time . I wouldn’t hesitate to swing a rv motor into it and get it back going while the whole deal is fresh in your head where everything in the truck fits,goes. I’ve seen too many trucks get a full motor rebuild and not make 20,000 miles in the rest of its life. I’ve done a ton of short and long blocks over the years and only had one bad one and only one re ring cheepie build go south. And both were not from bad parts

 

[SamuraiKodish]

Currently deciding what to do with the EJ25 in my Subaru I just bought. All the junkyard engines i'm finding have higher miles. If I go the junkyard route i'd at bare minimum reseal the whole thing.

 

[Gdogg]

I do a lot of diesel work and some gas stuff, I buy almost everything right from the dealer. I did a 5.4 3V timing chain and phaser job right after Covid started and a lot of parts were on back order from the dealer, so I used a Cloyes chain and guides, it didn’t go 9000 miles and a guide broke, the chunk of plastic jammed the chain and broke it.
Then I did a 3.5 Ford phaser, chains and water pump, again I used Cloyes chains and guides. This engine went about a year and the same thing happened.
Both these jobs I only used Cloyes chains and guides, everything else was from the dealer, but the guide ruined the job along with both engines.

If you are buying parts online and they are saying that they are OEM there’s a really good chance they are counterfeit. I’ve been burned on them also.
I’ve been wrenching for over 40 years and I can’t think of one time an OEM part failed.

 

[PAE]

The only drawback to a GM crate 5.3, 6.0 or others in that series is they still have AFM/DOD, and swap out the parts and you just voided the warranty.

Kinna stupid

 

[AKnate]

Sen

Been thinking about this. Don't know what to do with the rest of it though. Cut it up and throw it in the dumpster?

Like GM SBC the 5.0 has so many parts options I would feel much more comfortable doing that series engine. Have a 350 I did a couple years ago hanging in there strong with no failures yet.

We did studs on the engine we are pulling, been there, done that, But yeah I bet your right.

If you rebuild it with normal off the shelf parts, do you think that a rebuilder would use anything better than that ?

This is where experience comes in. I would imagine a rebuilder has some kind of relationship with their supplier, they either trust the parts they are getting or they move on, or they go broke doing warranty stuff.

Then I did a 3.5 Ford phaser, chains and water pump, again I used Cloyes chains and guides. This engine went about a year and the same thing happened.
Both these jobs I only used Cloyes chains and guides, everything else was from the dealer, but the guide ruined the job along with both engines.

Had that same experience with Cloyes as of late as well. Too bad, Cloyes used to be the thing.

it ain't bad to do, especially with the motor out
but people are stupid whiny wieners

 

[shortbus4x4]

LS swap it.

 

[Levigarrett76]

Pull it and tear it down and see what you find, then decide. I am leaning towards JY engine.

Are there any other vehicles in the fleet that might present a rebuild together opportunity that are a more common platform with better parts availability? Ford/chevy smallblocks/big blocks, 5.9 cummins etc?

 

[junkytj]

In your context, used motor all day.

If I'm going to do one myself, it's going into something that I plan on keeping for the rest of my days. It's about time. It takes a ton of time to track down quality parts, find a good machine shop and wait your turn for them. Researching the particular issues and methods to put it together correctly. My time is finite, spending it on an appliance vehicle is not my thing.

Reman - Has the theoretical advantage of being a new engine if remanned properly. The problem is as you have identified parts quality is currently shit, so then you are dependent on the reman warranty department. That is always shitty and time consuming.

Used was put together with factory parts and I can check compression and leak down. I can run water through the coolant passages before installation, sometimes I even get the accessories, so I end up with spares.

 

[arse_sidewards]

Doesn't help that the people in question are fucking retards with no frame of reference for what they're dealing with.

Some CA flat rate super tech trying to extract a broken stud is going to go about as well as King Charles trying to mount a tire with spoons.

 

[Gdogg]

Had that same experience with Cloyes as of late as well. Too bad, Cloyes used to be the thing.

Doesn’t that just piss you off.
When do a job I don’t want the customer to ever have the same problem again, I really hated for these people to have problems but it’s a problem from the quality of the parts not work.
