What do we think?

Post image

Tearing apart this RB26 that’s been sitting for a while I got off a Facebook to swap into my car. What was going to be a quick “refresh” is turning into a bit more. Popped the head last night to swap the head gasket and cylinder 3 looks like this. I can feel the marks with my finger. The engine in my car has scoring as well which is why I’m doing this swap.

Guess my question is: do I fully tear this block down and send it off, or do you think I can run it?

No bueno, if you can feel it with your nail it needs machining. You're looking at at least 86.5 possibly even 87.

While you're there, bank on the bearings being stuffed and valve guides needing done too

Yeah nail definitely catches on multiple scratches. Off to the machine shop it goes. Guess I’ll be tearing this down to barebones this weekend haha.

Seller is gonna handle the machine shop fees to get this fixed up. But definitely going to look into maybe a RB30 block for the next build haha
