Blown Head gasket rebuild....@297k

I would change the engine and invest the rest of the $175,000.

 

My 2010 Gen.III with 320,000+ had been consuming oil @1qt/fill-up for more than 150,000 miles when the head gasket blew and of course I have the usual knocking on startup and coolant loss. I'm here trying to decide on rebuild vs. replace the engine. I'm new to the Seattle area, having driven my Prius from MA (head gasket blew somewhere about Missouri). The hard part(?) here in the PNW is finding a good mechanic without my any local experience; not fond of the Toyota dealers BTW. So far no one will do a rebuild!; I can only find referrals to the SF or LA areas, many days drive to the south.
*I'd appreciate any leads to someone in the Seattle area who can competently drop in a remanufactured engine, and leads to places selling a decent remanufactured 1.8L for my 2010.*
Many thanks in advance for your help!

 

Probably no rebuilt s per se The JDM people are all over the country ATK started out in California and then moved across the United States now JDM has done the same thing they have outlets all across the United States I don't know what's closest to you but I can find out real quick A rebuilt 2ZZ FXE I don't know The place here down in Fayetteville North Carolina they may do them I don't know

SM-A715F ?

 

been rebuilding my 2010 Prius. Classic oil-burner. EGR pipe is completely packed. Intake manifold looks like a coal mine at midnight. But, best of all is the number 4 cylinder.

Yeah, that's an exhaust valve with a hole in it. Believe it or not, #4 cylinder is actually the cleanest of the bunch.


Here's one of the entrances to the coal mine, erh, I mean exhaust manifold.


And, of course, the classic carbonized oil control ring, plus assorted other goo, gum, and grit.

Anyway, my real question is this: I'm about to order parts for the rebuild. I know that the numbers stamped on the block are related to the main bearings, but I'm not sure how to find them all or how to decipher all the info.

Anyone out there now what
32
3
33
Stamped into the block means?

There's also
UN
RE
Stamped on it.

What other places do I need to be looking to get the right rod bearings, and piston wrist pins, etc.?

I'm a newbie, so any help is greatly appreciated.

Thx

 

Again, I'm a newbie at this, so my apologies for the roughness of my post

I didn't give any specifics about my car:

• 2010 Toyota Prius, Base package.
• 144K Miles. Began burning oil at 98K.

So I was imprecise in my first post. I said the numbers were on the block. Here's what is actually on my engine. I hope this helps you see what I'm trying to figure out:

On the engine block: 33233
I'm guessing these are for the main bearings, but there are other numbers on the crankshaft that are different.

On the Crankshaft: 32333 and UNRE
So I'm guessing 32333 is for the main bearings? Again, this is different that what's on the engine block.
I have no idea what UNRE means. The only guess I have is that we have four letters and there are four rod bearings.


And finally, the pistons and rods:
Cyl #4: B
Rod #4: 9 End Cap: 18
Gap #4: 2GB

Cyl #3: B
Rod #3: 9 End Cap: 18
Gap #3: 2MB

Cyl #2: B
Rod #2: 9 End Cap: 18
Gap #2: 2MB or is it 2WB?

Cyl #1: B
Rod #1: 2 End Cap: 18
Gap #1: 2RB




Just for reference, here's what the EGR pipe looks like on the exhaust pickup end. What an absolutely stupid design.

 

No kidding...

144K miles isn't much, for that degree of carnage. Have you had it since new?

 

Nope. I bought it at 77K when it was only 18 months old, so previous owner drove the snot out of it. I knew nothing about the EGR-pipe/oil-control-ring problem when I bought it, so when it started drinking oil at 98K I was surprised. Priuschat was a godsend for me. I kept pouring oil into the thing for the next 56K miles. Should have bought stock in Valvoline. Even drove it across the country in the summer heat, adding a quart every 300-400 miles.

Performance-wise, it's always done fine, until about a years ago. I was driving at highway speed and it just started bucking terribly. I drove it home (gulp), and parked it. I guess the hole in the valve got to be too much. Anyway, I decided to take the motor out and rebuild it myself (life-long dream of mine, to rebuild an engine). It hasn't been a bad experience. I've been real careful. There are lots of good videos out there that have helped.

I'm at the point where I need to order parts: main bearings, rod bearings, pistons, rings. If I'd know better, I would have left the bottom end intact, but I opened everything up to check clearances. I gotta say, Toyota engineering can be fantastic. The whole engine was in great shape considering what it had to go through with the EGR pipe nonsense. Not a speck of sludge or gunk anywhere. I'm guessing pouring gallons of synthetic through the crankcase helped a lot .

I'm washing everything down with Super Clean degreaser (love that stuff) and am about to lap the valves, and start reassembling it. Believe it or not, it's all cleaned up very nicely. The valves and valve seats a little rough, but I've got several grits of valve lapping compound to bring them back. Otherwise, it all looks very doable.

 

What would it take to bend that rod? Some serious friction in the cylinder?

 

Water in the cylinder. A liquid doesn't compress. The rod usually bends

 

You can get a New Short Block for $1300

 

Or sometimes breaks and punches holes in the block. We had one in the shop recently with a hole in the front, one in the back, and one in the bottom.

 

Specifically: coolant, leaking past the head gasket.

Link? I'm not doubting, just wondering where that deal is.

 

Thats a bot. He just copied and pasted a sentence from page 1. Not sure why bots love to practice on forums.

 

Ah geez, he's quoting me.

I've learned a bit since, lol.

 

??? What are you writing about???

 

From page 1:

 

That "bot" has been here a heck of a lot longer than you have.

In 949 posts on this thread I'll bet there are plenty more duplications although I didn't find an actual verbatim copy & paste.

@ASRDogman, in the future, please read and memorize all comments before you write anything, even if there are a thousand of them. There's no excuse for saying anything similar to what someone else said. [wishing for a "tongue in cheek" emoticon]

 

I'll give myself 40 lashes with a wet noodle...

 

And let that be a lesson to ya!

 

longer than who? The account that posted #948 was created last Friday, and made four posts.

All four of the posts were sort of strange, Three of the four were a direct copy/paste of a sentence or two taken directly from something on the first page of the same thread. The one that wasn't, probably was still copied from somewhere. It ends with "You can see the proper guide here." but lacks a link or any attachment or guide of any kind. It's the kind of thing you would get by copy/pasting text from another post where "here" was a link, or where there was other information you didn't copy.

That might have been a way to try to get the requisite number of first posts, without posting obvious gibberish.

Or it might just have had something to do with the date.

I'm still trying to figure out who is pretending to be bisco and adding "?" at the bottoms of various threads.
