New CPL# for rebuild

[Rawze]

(02-26-2019 )NoTime Wrote:  Rawze I got ahold of Mr. Haggi ( I hope I spelled that right) and got some good information and so very near future help from him. And he was very addiment about counter boring the block and liner protrusion. My problem is my mechanic is 100% sure my block needs no machine work. He showed me the seats for the liners and said they are fine but I might as well be looking at the inside of a brain I don’t know what to look for. This guy has been rebuilding Cummins and Cats for 25 years and that’s all he does and everyone says he knows what he is doing but I’m kinda worried about not counter boring the cylinders!

Am I being to anel and demand the machine work or trust this guy??

Also huge shout out to Mr. Haggi!!! It’s about 600 miles from home to his shop but he is my engine guy from here out!!!

You can do what you want to, its your livelihood your pissing around with there,... All I know is that if it were my own truck, It would not be up for discussion. even if it were a brand spanking new short-block,. I would have pulled it apart and counter-bore to set the liners to 0.014" (or 0.015" if big HP ). Aren't you paying them?

- That is the problem with mechanics who do things for 25+ years,.. They are generally arrogant, stubborn, and don't want to do anything outside of the little box of thinking they have cornered themselves into by living in the past. makes me wonder what else they don;t do correctly, as it is even more common for mechanics to have many other bad habbits and mis-conceptions after doing such tings for so long.

- no wonder they have problems with ISX engines,.. They apparently don't know how to build one up right, the people they are using for programming are horrible, and the list of foreseen problems is starting to get long real fast over there it seems. - how many times have they torqued a head and let sit as mentioned above, then re-torqued the next day? -- have they ever?

- Are they using an impact on that final 90-degrees on the head too? -- I would bet so. --- (*rawze(me) shakes head*)


25+ years and an argument about such things points right to a big red flag to me as it screams they likely have a LOT of other bad habits to go with their apparent short-sighted knowledge of newer style red ISX engines and their higher compression requirements.

I would not trust them to hold a screwdriver if that is the case. Sounds like they are the typical shop I would tell people to run from like hell.

===========

You say the engine failed due to carbon packing and not a head gasket failure. In that case, it may very well be that there is no visible liner fretting signs yet, but I guarantee it will not last a million miles the second time around if you don't counter-bore it. You would be lucky to get 300-400k more maybe. Expecting it to last another million would be like claiming you could go 1.6 million at 500+(or600+)hp without any fretting,.. good luck with that, I want some of what the guy is smoking so that I can live in that pipe dream utopia of ignorance too.

Are you building it into a 300k mile engine (considering the ~600k on it already and it not machined)? -- or a million mile engine? -- That is the difference.
