Aganit, good for you! Santa came early. I find what you state they did a bit odd. Iv'e had IAP sensor's cause "surging" issues but never witnessed a turbo or idle setting to cause this. Did they re-flash your ECM? Maybe member Cat can ring in on this.

Yep the IAP or a sticking actuation solenoid can cause a surge, not sure why at low idle or when coming to a stop. But the cleaning of the turbo and readjusting low idle not sure why that would change anything, but I don't know how to clean a turbo while its installed, other than a surface cleaning of the compressor wheel. Oh well, its running good and that's good. LOL Merry Christmas and Safe Travels.

There is an inspection procedure in the CAT workshop manual on how to inspect and clean the turbo, the cleaning part deal with the oil lines, if they get clogged. I recently inspected my turbo because i was looking for an oil leak. it had some carbon dust on the exhaust side fins but it was light, no oil residue. So I am an not sure you would want to dump a solvent in there.

Cat, that is my quick 5 minute diagnoses on "surge" issues. Unplug the IAP. If the surging ceases then replace it.If not, then I go to the solenoid (most of the time it's a hi impedance on the coil connector contacts). Most of the time it's either or. I have a spare IAP at all times in my on coach. $160.00 is cheap insurance when your on the road!
All in all, I find the Cat system pretty simple to diagnose in comparison to other's designs.

Folks, like what happened when Jesus healed the blind man i dont know how, i only know that the thing was tore up and now it ain't. Whatever they said they did is ok with me, i wish i could be more helpful to this site by explaining everything in vivid detail but i simply don't know. I am an old retired air conditioning contractor of 35 years business ownership and have been retired so long have almost forgot all that.
My wife and I love you folks on this site,and hope you have a wonderful Christmas.

Well curiouity has got the cat .
Im going to have to take a look at mine while im in there doing other work .
I have looked at a few videos , and yes if one wants to clean one . You will have to take it apart to do it correct .

If this is true, the filter must be to protect the downstream fuel injection system, perhaps from shards resulting from an HEUI pump failure, and obviously would not help longevity of the HEUI pump? Of course, I'm just musing and obviously I don't know, but for that money plus $1300 labor, it's got to be more exotic than the normal, everyday in-line oil filter.

I'm guess that the kit can be copied with parts from a variety of manufactures and with installing it yourself, the savings will be significant.
So now, what's the diff between putting one on a C7 and a C9, for example?

See post 46 total parts is like $200.00. The kit price of 1600 includes a HEUI pump. Merry Christmas Safe Travels!!

For a C9 you could use the filter but you have to make your own hoses for the inlet to the filter and from inline filter to HEUI.

Well, that certainly helps, as those pumps aren't cheap...

Any reason why one couldn't do that?
So this thing goes in between the lift pump and the HUEI, where there is none now and with the Primary and Secondary filters being between the Lift pump and the tank?
Did you not mention before about the HEUI failures not being so much of a problem, in the C9 and maybe why they only have this kit available for the C7?

The term lift pump implies fuel as does the terms Primary and Secondary filter. This filter is a inline oil filter. It goes in the line from the main engine oil galley to the HEUI pump. There were HEUI failures on the C9 engine also but I do not know the failure rates of C7 versus C9. Just an opinion the C7 had a higher failure rate than the C9. The failures were worse in some applications than others. The C9 HEUI had a very failure rate in compactors.
Have a Merry Christmas- Safe Travels.

Well, that certainly clears that up and don't know why I had my head wrapped around another filter for the fuel. So, this is the answer to the possibility of dirty oil and maybe not having to change it so often, or so it seems.
Merry Christmas and safe travels to you and yours, as well!
