Well, i would put the engine on an engine stand, flip the block upside down, push that piston up out of the way, and get to work on it with a toothbrust and some brake cleaner.... make sure all that crap runs out of the block when you clean it. THEN, post some more pics of it on here so we can see it some more.
IMO, that would be worth a shot before taking it back to get it rehoned. Just make sure, that when you rotate the crank to get that piston out of the way, not to complete that pistons stroke to the top. i dont think you would want your rings to try and push that crap.
hope that'll help, maybe someone else can answer to this too.

Don't use brake cleaner on your cylinder bores. I would suggest WD40 or some other lubricant. The brake cleaner is going to remove all traces of oil and you are going to get nearly instant flash rust from the moisture in the air.

As far as your bores, you might be in trouble--tough to tell from a picture. I would go at it with some really fine scotchbrite and either WD40 or 3-1 oil. After the cleanup, if you are still in doubt, take it back to the machine shop who did your machine work and ask their opinion.

Thanks for the reply guys. Now i am not totally lost. I'll try all that out.

agreed. for some reason, WD-40 never even crossed my mind...
Let us know how it goes.

^ ^ ^ I agree- really tough to tell from a picture, but by how bright it is, I'd have a lot of hope for it being superficial enough to clean up okay. If you do have to re-hone, make it a very, very light pass. But I don't think it'll need it.

So I tried what you guys said. I put some wd-40 on it, I let it soak, then I scrubbed and here are the results.





Doesn't look good. :thumbdown

Ulgh, CRAP. No, I don't like it, either. Time to ask the machinist.

What a damned shame.

But damn, great pics.

Thanks.

Have nothing constructive to add, but damn this man can take pictures that ilustrate his point correctly.

to you sir!

Thanks man.

What camera did you take those pics with? Those are some fricken nice close-ups.

It was actually a cheap Fujifilm finePix 2300. Thanks. Now I gotta go get the cylinder rehoned.
