88. What you see in the pic is not a crack. It is a ridge. I put a bolt that was too short in it and instead of the bolt stripping as I torqued it, it broke the iron that was from the threads of the block back to the timing cover.
Now there is a difference in surfaces. What broke off was about the width and size of a nickle. Somehow I have to get the surface back-up before the TC will seal properly again.
But I really think it's just skrap metal now. Great running block, and all that work I did to make the Hybrid work, gone...sucks b/c of that little break.
slightly different pic.
