AEM Filter is killing my 7.3 . . . check this out
Thought this would be of interest to those of you who have an AEM filter for your truck or are considering one. I WAS running an AEM Dryflow on my '96 PS.
I got my oil analysis back from Blackstone yesterday along with a personal call from the regarding the results. Silicon went from 7ppm to 29ppm!!!! They said to check the intake for leaks, etc. So I did. A visual inspection and pressure check showed nothing. The AEM filter was a bit dirty on the outside but not damaged. THEN, I looked inside the filter and saw sandy dust everywhere. The inside is supposed to be the clean side!. The filter was installed ~8000 miles ago on a DIY intake and cleaned ~4000 ago according to AEM instructions. I secured paper to the bottom of the filter and tapped it to get the stuff from this inside out. I have attached pictures to show the results! I feel the AEM filter is killing my PowerStroke.
I have contacted AEM and hopefully will hear back. I'll post the response. I hope with a new filter -- probably a 6637 type -- I'll be back to normal on the silicon soon. I hope there was not too much damage. More pictures on webshots at:
