Good point, fair enough. It's been 160k miles since 2003, but it's only ever overheated on me once, not when it died though. I'll look into machine shops around the area and see what's up.Just by torqueing the head can warp it. If been on there for how many years? I assume it over heated and u spun a rod. Spend the 200$ and get it decked.

I'll take a closer look at that spot, to the eye it appears as staining.All in that area. The corrosion and narrow lands is a common place to fail. The corrosion is part of the reason to deck surfaces. But you’re almost ready to assemble now.. just for reference.
Gave the surfaces another look over, any corrosion seems to minimal and that surface is nice, smooth, and shiny. I will keep it in mind either way, and I'm getting ready to start the initial assembly. I was looking at the rod markings I have:I'll take a closer look at that spot, to the eye it appears as staining.
The first 3 are the originals which hadn't taken any damage during the failure, last one was ordered off MWR. I have calipers that I can verify the bores of rod journals, and I already have the verified the new crank is perfectly uniform across them as well.They only refer to the original build off the shelf. After that run wot ya brung..
You’re replacing a rod so you don’t have a set.
If I had stripped another motor to get my new parts ( as I have) I would use the 4 set in my ‘new’ build. Not just random ones.
highly recommend you take your 4 rods to the engine shop, ask them to align the rods and confirm the journal size, they may suggest line boring the big ends which almost guarantees them to be correct.
that said I used to work with a bloke who would walk around a wrecking shop, look down and say.. “oh that’s a good 1275 mini valve,” pick it up and into his pocket..
Oh ok, I hear you, I was reading about rod twist in the repair manual but wasn't sure how much it comes into play.Another engine building thing., so it’s a 2nd hand rod from mwr?
Aligning rods ensure they are straight and the journals are true and in line. Life on engine internals is harsh, they can easily develop a twist.
