Engine/Transmission (1994 - 1998) Last oil sample??

[CumminsPower98]

I just got my last sample back from Oil Analyzers out of four I have done so far running Amsoil Series 3000 5w30 HDD and the copper is way up and the lead has been coming up some too. Below I have listed how the trends are going with miles on oil to the left side.

My question is what on earth would cause this other then bushings and bearings wearing. The only thing I have done that I know of during this last oil change was to rebuild the turbo. As far as I know all the soft parts in the turbo are brass so I don't see how that would affect it. Any ideas? Also Boron has come way down. I know there are many variables and I'm not too worried but the copper just stood out to me and made me wonder. My silicone is still coming down since going to the BHAF after running the drop in K&N for a while.

The truck has 107k on it now and the my oil sampling began at about 69k. I finally got a bypass system ordered to help out. I do a lot of short trips, which I know is not the best on things. Thanks for any input on this. - Mark -

Oil Analysis

CumminsPower98,



I would give Oil Analyzers a call and run it by them. They will have your sheet right in front of them and have seen many different senarios, so I am sure they can help you out. I believe the name of the guy you need to talk to is Dan... Oil cooler is copper???



Good luck, I hope this helps.

If my memory is correct(rarely),I think brass has copper in it. May be from the turbo bushings? Im not sure how it would read on the sample tho. Other than that you should give them a call.

Thanks guys!

Last year I changed the exhaust manifold on a John Deere pump engine, this required removing and reinstalling the turbo, on the next sample the copper had gone from 2 to 65, the following sample went down to 10 and after that back to 2 or 3. I was extremely careful with the turbo oil lines but I feel I must have somehow contaminated something. I'll bet the high copper is because of your turbo work.

I sure hope it's from the turbo work as I see no other reason for it. That makes me feel a lot better, jrobinson2, since you saw a similar thing happen.
