Can I replace rods and pistons instead of buying a new engine?

Hi Scotty, I have a 1998 Honda prelude automatic base model with 170,000 miles. The engine started to knock and one day it died. It had no oil in it when I checked. It sounded as if a rod broke completely. I was wondering if I could replace the rods and pistons instead of buying a new engine.

You're probably throwing away a lot of money, time, and labor by replacing rods and pistons.

What is the condition of everything else? Crankshaft, bearings, cylindricity of the bores, any valve or head damage, and a whole engine full of parts that have been directly affected and/or damaged.

Usually such a vehicle would be scrapped, but if you want to save it, either get a salvage engine, a short block, or a long block.

If you do a short block, you're taking a big chance that lots of other parts are still usable.

Same on a long block, but with fewer parts to re-use.

And to do things right, you need to know a lot about the "idiosyncrasies" of that 2.2L engine. And having several of the special tools needed would be helpful.

Been there done that, so LOL.

Even though you could, it doesn't mean you should. I would personally either scrap the car or....if you LOVE the car....buy a new motor. Rebuilds on those engines are extremely tricky and very expensive.


@mod_man
I agree. Better to buy a new/used engine than to rebuild this one.

You have to at least take the block to a machine shop for inspection and cylinder honing before you rebuild the engine. Try to look around in junk yards for a engine if money is an issue and the block is wrecked. You don't want to put new pistons and rods in and just blow the motor in 100 miles.

It's time to let her go.

You have a 23 year old vehicle and you're talking about a huge job even if you just decide to "risk it" and buy an engine from a junk yard.

The point being, if you're wiling to do that much work

you can probably find an 8 or 10 year old Honda that needs an engine for almost nothing.

 

At least putting the labor/cash into replacing the engine on a much newer Honda would make more sense than bolting a replacement engine onto a 23 year old transmission in a car with 23 year old parts
