Girdle comes line honed with block. So get a new block, that one is trash.

 

No chance those are casting flaws that can be sanded?

 

Is it really worth the chance for a $500 block

 

Nah, just bummed I spent all that time tearing it down since most (if not all) of the OEM internals are not gonna be reused. Only bought the car cause I knew it had a K24 with a 5spd M/T.
Oh well. Could definitely sell off most of the K24A8 parts. Time to look for a bare bones block.

 

Those are not cracks. They're casting lines where the mold had cracks. They're not a problem.

 

Get it X rayed for your piece of mind. Doesn't cost much. N/A is one thing boosting it is another. I used to work at a foundry and yes Byorn.

 

casting marks from the mold surface cracking

I also dipped professionally into casting helping getting the manufacturing process of these to scale. Vacuum centrifugal near net shape casting.
Titanium aluminide exhaust turbine blades for the GE genx engine used on the 787 and 747-8.

 

I operated a LAMPE it's German made. I produced molds that then went to casting. I was not in charge of quality control so as you can imagine, if it came out of the machine it went on the rack. This was back in 2006. ALOT of what I did was for Volvo Penta. They were boat parts. If your plane goes down in the ocean. I will be there for you. 😁

 

"engines stop, passengers swim" was an euphemism used to promote quality.
These things and processes pass a LOT of quality checks. They cost a couple of Gs per piece! And there are hundreds in an engine.

 

I don't know what to tell you? lol I was making pieces for outdrives. (boats) You know how I feel about Titanium It's just neat. I was minding my own business making sand cast molds. I was not making a couple G's per piece. But it was piece work, as in I was required to "make rate". Your not the real police and I don't know where your going with this but I didn't do it.

I'm just messing with you man but I would not want the responsibility of making blades for an aircraft, that's for sure. We have some sayings also. " When my ship sails". "when my ship comes in". You might be onto something with this whole "I'll just go swimming" thing? I'm going to respectfully decline your offer and stay on the boat. I'll route for you though. Paddle lotus paddle!

 

Lol
