I am sad to say that there has been a death in the family. I almost shed a tear today I walked into the shop and on the floor sat not 1 but 2 blown dmax's. I had to go sit in the office for a while after that. we have had a few calls for rebuilt dmax's but never had to rebuild one yet, now I have 2 sitting on the floor of my shop. Oh well it was only a matter of time. will get the rebuilt and back on the road by next week.

Good catch Mac, typo on my part. I was simply curious what he was going to do for rebuild parts, not a jab at spelling....hehe

get the sleeves from Napa or Grangier My father in law is the owner of the shop and yes the MOTORS will get rebuilt. I run the boring bar and will bore them out and put a sleeve in the MOTORS. Then the ENGINE assembly man will reassemble the MOTORS for delivery to whom ever would like to buy them. The MOTORS were a pot luck draw in the weekly core MOTOR drop off at the shop. Have a great day.

HP here's the plan of attack
1. get duramax block off shelf
2. wire brush top and take a looksy inside
3. if hardened inlay is present will try as long as I dont go 0.030 over
4. unless you have better advice we havent done one of these yet.

help would be appreciated thanks

I was curious about your sleeving comment, Shawn, I don't think anyone has sleeved a DMax as far as I know (which isn't that far, actually - but I would have remembered hearing or reading about it). The DMax cylinder bores are induction hardened - one of the unique features of the engine.
