friends 1993 prelude vtec stopped running, so I pulled the head off for him and this is what I found:



Pretty rough, took out the piston, scored the bore, killed crank and conn rod, etc.

no holes out the side though. 200k miles on it. Im suggesting this:

Holy **** MANG! That is fantastic. Why replace? Why not rebuild?

 

ouch... yeah i picked up one of those h22s. few things wrong with it but overall good buy.

 

i dont think its rebuildable, and it has 200k on it. The cylinder wall is scored pretty deeply, i dont think it can be fixed.

 

You can sleeve it.

"That's what I'm talkin about!"

And it would be bulletproof.

 

how do you sleeve it? i didnt think that that engine was sleeved. Does it have to be machined?
gimmie some more info, maybe its a project ill tackle!!!!!!!

You won't be able to tackle that by yourself, unless you have your
own machine chop.

Try looking up Darton Sleeves or Golden Eagle Sleeves

 

^^^ Benson too. Search archives for username Earl for more info.

I have access to a machine shop and am capable of pretty much anything. Are the cylinders machined out, and then the sleeves dropped in? im not sure if that would be worth it. I can get a used motor for 2k, and the car is stock. its not my deal, its a friends. if it were me, id think this is the perfect time to build it up!

Yes it is machined this way. Some material is bored out and new sleeves are pressed in or whatever. A sleeved engine gives you more options at the start- you can choose NA or turbo way. However you can have forged pistons of any compression dropped in and you will not worry if those pistons scratch your cylinder walls.
There is also one thing you colud consider- you never know how healthy a new engine is... What if it breaks in the near future the same way??

 

hmm, well , like I said, it isnt for me, its for a friend. its a 93 prelude in kinda rough shape. About 200k on the clock. He isnt really into dropping money into it due to lack of funds. I wasnt sure about rebuilding a 200k motor, whether its worth it or not. So i found this and suggested it to him:

Seems like a good deal to me. Im doing all the labor for him for free, cause im a damn good friend, and I also enjoy it, and am learning a lot. what would you do under the circumstances? rebuild a 200k motor with stock parts, or by a used motor?

 

It's not only 2k$ he will spend. Count shipping, some stuff will need replacing etc... He doesn't need to buy a new tranny, does he? Maybe he would better buy only new engine without ECU, tranny and other stuff he is having at the moment in working condition?

 

uh if the crank and conn rod are damaged as he said...I wouldn't touch that motor

 

aaa yeah I skipped that... Definitely buy a new engine.

I would go this route

 

Heres a pic of the complete damage, its pretty ugly lookin for sure

 

Looks like a rod bolt failure to me. Get a new engine. Crank + sleeves + pistons + rods + labor = more money than a longblock swap.

Poor motor....

Thats what I figured. With 200k on it, and that much damage, who knows what damage the block incurred. My vote is for new engine, but its not my decision. Maybe he should just sell the car without an engine and start fresh :/ But im willing to swap engines for him. (My first swap)

Not sure if it was the rod bolts, you can see the rod lying on the bottom, I think it was a lack of ouil issue, the rod is snapped.
