B21A1 Horror!!

Got a bottom end for free the other day and just took a hour to tear it down. Here is a link to this bottom end. We think it is out of a 1991-1993, I am guessing, Honda Prelude. It had been sitting at a friends house for a year and his dad wanted it gone. You might like the pictures. Wasn't pretty to pull apart and is very dirty. Just a reminder to keep your motors clean too!

Here's a few pictures!!

Guess how much of the timing belt is wrapped in there?


Yes the whole thing! Don't ask how this happened. I don't want to know myself!


Keep the oil changed, having sluge can hurt your motor!


Hmmm, spun bearing?!!


Best case scenario is that the cylinders will need honed, the crankshaft will need polished, mains line honed, and rods will have to be machined and polished. About $400 in work and $500 in parts. Then new bearings and rings ordered. If he had kept the oil changed and the outside of the motor cleaned I bet none of this would have happened!!

poor poor engine.

it must have had some awosme down hill action when the belt snapped, and kept the motor turning. lol

thats a good effort for a snapped belt.

[Slow96GSR]

It wasn't snapped, still all in one piece, almost. It has a cut half way thru it so my guess it that's how it got off the cams.

B21?
I thought B20 was as big as B series ever got to?

Wow.

Any idea when the last oil change was?

[Slow96GSR]

Yup a B21. And no we have no idea on the last oil change. It was messy tearing it down too. I used all my rags so now I have to order more!!

Looks pretty horrible.

On a side note, re: rags (yes I know you are in the US), the local auto store that I was in over the weekend had a 'bag of rags', that were made out of recycled clothes etc. Thought it was a pretty good idea, plus you are helping the environment .

[Slow96GSR]

Ya, I was being sarcastic though. I just get mine off a truck after they have been cleaned. I get 500 at a time and then when they need cleaned the truck drops off 500 more and takes the dirty ones. As for recycled rags, we get those too, like if we are working on stuff where they will just be tossed after the job.
