Picked up this seized 8.1 block this weekend for cheap. Keeping some of the parts for my build, and likely scrapping rest of block. Guy lost #1 & #2 rods out the oil pan.

I don't think this block is usable at this point anyway? (I'm sure someone will set me straight)

Wife was thrilled that I put a BBC in her Scion! :haha:

Well, I'm gonna go out on a limb and say the pistons are probably not reusable........
Nor the crank.

But, I'm not totally sure about the block.
Depending on the exact location and other particulars of that gouge, it might be salvageable.

If its below the bottom travel of the piston it might not hurt anything.

I was thinking the same thing, but then add up all the damaged parts, and you might pay more than a good running engine.
 
I'm far from an expert, but it may be worth having a machine shop check it out.

If it didnt hit water or crack, its fixable.
 
The block is useable, and the crank is salvageable. The crank would need to be welded then reground and the block could be bored oversize and nothing to worry about as far as the chunk missing at the bottom of the block.

He has spoken :bow::bow:
 
I agree about the crank, I have seen worse ones than those fixed, but I was not sure in this day and age if it was worth it, or even if anyone still did those.

I just figured a junkyard or rebuilt would be more practical. It has been a long time since I had any of that kind of work done, and almost that long since I walked through an engine re-builder's shop.

I don't think there is but one left in town anymore.

this was my thought, I never said it's not feasable, just not cost effective.
I had a bad crank on my 6.2 diesel, they wanted $600 to grind it and nitride it, I got a complete running engine for $350 and I was done.

As much as it pains me, this thing is likely headed for scrap. I really don't need another "thing" to trip over in my already stuffed garage.

And your point above is spot on - I paid $900 out the door for my 8.1 going in my K5. Into this one $50 right now, and it's my third 8.1. (I have a disease!)

I don't think it would take long to pass the $900 - $1,200 range fixing this engine, just getting it back to a useable bottom end.
 
You call that carnage? Looks like it needs a rebuild to me. :D I thought I was going to see some real carnage.
