Or would you buy a reman with warranty?

Or put a used engine in?

Context, My son has a 2V Ford V10 that is worn out. He wants to overhaul it.
I kind of want him to do it so he can learn more stuff while I am still alive.

My fear is replacement parts. This is a 2001 engine. Little to no OEM parts available.

Sourcing parts is hit or miss anyway. I cannot buy a kit with "quality name" parts.

Buy new valves, will the head pop off one in a year? Valve springs will it break them weekly? Will the piston rings seat? With the new pistons crack and break?

Even the machine shop, will they grind the valve seats correctly? Bore the block correctly? It only takes one mistake to ruin the whole thing.

I can't remember the last time I had a good experience in overhaul parts or machine shops.

In recent years I did a Mitsubishi 2.4, rings didn't seat. Had to pull apart and do again with a different brand of rings. I think that one had new crank bearings that were off spec too.
Ford sport trac 4.0 cloyes timing chains sets, failed one after another.
Isuzu. 2.4 had 2 of the 6 new pistons break between the ring grooves in the first 1,000 miles. On second attempt rings didn't seat. Sold it as is.
VW 1.8 turbo, popped the head off a brand new valve in the first 100 miles.
The list goes on.

to say I have no faith in replacement parts is an understatement.

How do you buy parts with any confidence?
 
100% bacon.

I'd drop* a used motor out of a wrecked truck. That's generally what I do for older cars, or no resale value. Or find one out of an RV.

*edit word.

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?

our dump takes them whole, but you have to pay a lot to get rid of them.

Park out back for son to live in? :flipoff2:.

I would rebuild the engine if I have time, we have one or two covid era sb350s, one is still in the crate, the other in in a truck.
 
I'd find a good used engine since it's an old truck. You can probably find a reman unit for less than the cost of rebuilding now days.
 
If I blew the motor up in my wheeler (2002 3.4 Toyota V6) I would overhaul it myself and not worry about it as I can still get OEM parts for it. The DDs is probably just swap the motor.

It fits in a lot smaller dumpster if it catches fire first. You know the wiring in old RVs just can't be trusted. Mouse probably chewed a wire or something.

If you look on car-part.com junkyard database there's a v10 without EGR for $1000 with 135k on it in Iowa.

Yes you can, I was seeing remans for just under $3k.

Of course you only hear the worst on the internet but the internet is full of stories of guys opening them up after a problem to find some pretty crazy stuff.

Seems pretty common to find one or 2 holes bored .060 over and the rest stock.
Or it should have been bored and wasn't.
Just all kinds of weird stuff.

Car-part is my go to. I have a couple local junkyards on there that have been great.

Used is my choice. My son wants to overhaul, but he doesn't fully comprehend what that entails or the lack of quality parts and this, I don't think, is what he should be learning on.

This isn't a stripped down rig where you can pull the engine back out in 45 minutes.

Often our opinions get skewed based on our personal experiences. Just wanted to come here and make sure I am not crazy thinking replacement parts are garbage before making a decision on this project.
 
I agree with those that are saying you should just put a used junkyard engine in it. Good luck with whatever you decide to do.
 
I rebuild them if I have the time available, both for the swap and the rebuild... so ~3 months intermittent.

My ranger shitbox thread is out there because I don't have the time and went to look at the reman and found that market is fucked as well.

Now looking for a good JY takeout.
 
An RV would be the LAST place I would look for an engine.

Think about it... parked for months on end (half the cylinders start pitting from moisture), then fired up, run a couple short stints, then running 70 mph with a car in tow across the state, parked for a week, then return. Do it all again next summer.

Most RV engines are roached before 100,000 miles from this type of life.

On top of that, you will then have to pay to dispose of said RV when you harvest the engine.
 
Depends on time and money. Throw a good used one in then take the time to rebuild yours good.

You say the engine is "worn out". How many miles on it. How was the maintenance done? What does inside the valve cover look like? Lots of sludge? low compression low oil pressure? How many spark plugs has it shot out?
May get by with rings and a valve job.

swap in the JY replacement, let him rebuild the old one as he sees fit without the rush of things. slide in the corner to sell for pennies on the dollar in 10yrs when the truck falls apart around the drivertrain
 
Trying to stick with Mahle/clevite parts I am at $1300 on Rock auto and I have not even touched anything on the heads.

Does not include machine work either.

Seems like a used engine is a no brainer.

But it is his project. I will let him decide and just try to steer him in what I think is the most sensible direction.
 
At the minimum, I would take the engine apart to see what's going on. Maybe just lap the valves, hone/ring, timing chain, water/oil pump...

How many miles are on it?

I'm mathematically old enough to have a kid that would be old enough to take on a project like this with him, but I don't have any kids.

But I can speak from doing projects like this with my Dad. So I agree with some of the other replies. This rebuild project might not be all about the $ to be honest. It's about the experience and learning process and doing it with you.

Depending on his age, level of interest, etc, maybe a junk yard swap would make more sense from a financial/speed consideration. But if he wants to rebuild it? What a cool project. So what if another route would be cheaper. I leverage experience learned from doing those projects decades ago with my old man way more often than I ever thought I would. I'd vote to rebuild it yourself, even if it did end up costing more (which it likely will).

Trick answer. LOL

My oldest son bought a rust free V10 excursion with 130k miles on it just for the body. That engine had dropped a valve.

So one cylinder, piston, and head are trashed.

His engine that we are removing has over 250k on it.

If he is stuck on rebuilding it, Then I keep telling him the cheapest, best option is to sleeve the low mile engine, re ring it, bearings, oil pump and timing chains, halfway rebuild one of his heads. He doesn't like that option.

At least not yet.

Doing that we could get something done in the $1k range. Similar price to a used engine.
 
Finally someone understands polls are supposed to include a bacon option:

On a side note, I wouldn't have a problem rebuilding my engine myself. However, it would depend if I have a spare vehicle to use while rebuilding.
 
Used engine. Get the truck back on the road.

My used engines get stripped down to long blocks, cleaned and reassembled with a new Felpro or OEM engine gasket kit (helps just in case you want or need head gaskets while its out) and reman parts that bolt onto it.

Then take the old long block and have him tear that one down and see if he still wants to get into it. You can always have the machine shop place the one in shop arrest while you guys enjoy the truck.
 
What does he do with this truck or did i miss that? I would say that is certainly a factor

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.
