Crack on the outside of block HELP! I did a cam and head swap today and on the second to last head bolt i heard a pop and there was a crack on the side of the block! I used an air hose to blow out any water before i started all the bolts because I KNEW this would happen if there was water in any bolt hole! Should I try to weld the crack or just call scoggins-dickey and by a new LS6 block?

Yeah i was thinking the same thing i was just in denial. Thought about going to an ls2 but sounds like to much trouble. I just want to get my car going again. Sounds like a lot or overtime this week.

Sounds like you didn't get all the water out. What kind of air gun did you use anyways? I prefer to use one with a rubber nipple on the end, really works well. Sorry to hear about the troubles, good luck.

I priced the lsx block but it is just a little more than i wanted to spend. If i was going to stroke it I would love to have a lsx block. I just got another 99 vette ls1 off ebay for $550. I just want the car going again to try my new heads and cam. I tried welding the old block for laughs but there is so much oil in the casting the crack is just trying to run. It might work for a couple of passes at the track. Maybe I will use it for an episode of PINKS with a 200 shot of nitrous! lol

When I bought my car, it was modded. Had a heads/cam setup. When we tore it down to do a different heads/cam setup, we found it had a crack just like you just mentioned. Never realy had any issues with it before, but it didn't seem to dyno as high as it should have. I would say get a new block.

I probably could have ignored it because it had two cracks on the outside of the block around the bolt passage. It did not get into the water jacket I believe but I want the car to run for a while so I just bit the bullet and bought a new block. I may try to use the old block for something else.
