One way to post pics is click on "Go Advance" at the bottom of this page.. then click on the "paperclip" icon in the tool bar... then click on "Choose File" and find your pic in your computer and upload it to the post..

The paperclip is just to right of the smiley face and just above the red X in the tool bar on the "Go Advance" page.. It might be possible that since you only have a few posts so far, you might have wait til you get 25 or more posts before you are able to post pic's... But, i am just guessing..

In addition to the many poor UOA results I've read about from 7.3L PSD owners who've run extended OCIs with by-pass filters and/or synthetic oil ...I also think that diverting 10% or more of the LOP flow from critical engine parts is a bad thing to do! Below are just a few ..."quotes"... from the BITOG site...

..."After almost 60 UOA's comparing/contrasting data logged for UOAs and bypass systems, I can tell you that there is precious little difference in actual performance when looking at UOA results."...

..."Blackstone advised dumping the oil. I just changed the oil, went back to 15/40 Rotella T and OEM full flow filters. I did this as I will make 2 quick changes of oil and filter and with a 3rd fresh oil and filter change sample after 3,000 miles. I went back to factory system as changing Amsoil full flow and bypass 3 times is too expensive"...

..."Pretty pleased with this sample. I removed my oilguard bypass and just ran a Fleetguard Stratapore ...the 15W40 dino performed just as well as the 5W40 Delo Syn I used to run for 1/2 the cost"...

..."Well Terry and I are concerned about the high FE trend that has developed. So the amsoil is going to come out and I am going to run a 5,000 interval of DELO 400 and resample"...

...and my own analysis shown below of many 7.3L PSD UOA reports indicates there's no "statistically significant" difference in UOA "Iron ppm" readings (which is the best indicator of "normal" engine wear) between a full-flow filter and a by-pass filter ...and if anything the engine's with by-pass filters indicate a little more wear than the ones with full-flow filters!
