Looks like it was burning some oil after all. Good shot of the tie-bar lifters.

Pistons and rods out.

You can see where all of the main caps were walking with stock bolts. For some reason I thought I had ARP mains.

16-18k on this LS2 chain. Being replaced with a Cloyes adjustable setup.

Bare block ready for some serious machine work.

Nice work

Sweeeeeet :thumbs:

Nice. :cheers:

Question: I notice what appears to be an LS1 style knock sensor on the side of the block. Do you plan to change to the LS2 style when the engine is finished?

I have heard (unconfirmed of course) that possibly some of the earlier LS1 KS's were not nearly as good as the later versions or the LS2 type. Other than the obvious design/mounting difference between the LS1 type and the LS2 type, do you know of any actual performance differences? A pro/cons on this?

I've had these knock sensors mounted on the back of the heads and on the sides of the blocks without any problems in either location. They work fine and I've never had a false knock issue.

I just heard from Shawn.....

Sleeves going it today. :party::party:

Jeez these guys are moving fast.

VA. Speed has an impressive in house facility.:cool:

I'm certainly no expert at inspecting engine mains......how can you determine by the appearance of the cap that it was walking?

Wow, I chimed in late as hell on this one. I've been out of town going on 2 weeks now. Still gone but just now getting on the forum.

Kevin! I am proud! You'd better take me for a ride in that beast when you get her back :)

I didn't read through the thread, just looked at the pictures.. when do you plan on having it back?

Wow, pretty interesting shots of the main caps moving on you, thanks for posting.

Were you the guy at ECS getting your coil overs put on while I was having my black vert street tuned?

You can see the high/low spots and the transfer of metal as opposed to a freshly machined look.

Yep, that is clear. What isn't clear is why the wear would be in an arc. I would expect the disparity to be linear.

Maybe the mill tooling marks when the caps/block were machined were in an arc? I'm not an expert, I just know a little bit. I'll ask my machine shop guy next time I talk to him.

That's what I was thinking. Photo's of this kind of thing are hard to take as well.

I would expect it to done in 3-4 weeks. We'll get together. :thumbs:

Nope. My coilovers went on in my garage with the help of some forum friends.

After hearing the explanation, I think the presence of "high"/"low" spots, as indicated by "clean" metal vs "dirty". (Actually I guess it's not "dirt" as such, but rather the presence of motor oil, etc).

The small areas of "clean" or burnished metal are just visible in various places. One example is the area directly around the bolt holes where, upon torquing down the caps, the metal directly around the bolt holes is being "stretched" slightly as the bolt pulls upward on the block and the aluminum block material becomes "burnished" against the steel main cap from vibration/movement over time.

I'm thinking that the "arc" visible in the pics were actually from the original machining of the surface and are (in this case) made more visible by the "dirty" oil at the microscopic level when opened back up. The "movement" is so slight, probably on the order of .0001 or so (or in that range), maybe less, that there would not be a discernible "direction" pattern as such. I guess the thrust forces are being applied in a more random or even circular manner, i.e. front-back, side-to-side, depending on applied power and rpm, etc. Interesting.

Hope that makes sense, cause even if it doesn't, that's my story and I'm sticking to it. :rofl:

Sounds good brother. You've got my number.

You really can't see the fretting in those pictures.The fretting from cap walk is actually metal transfer from one surface to the other.The arcs are from the block machining.

I got some good machining pic over on LS1Tech-i'll post them over here tomorrow night
