Ok I was curious on the quality of the XS copy and decided to do a direct comparison of each since I already had the Aeromotive FPR, I purchased the XS version I have not tested it since the ground is cover in snow but I thought the community would like to see pics of each unit side by...
I imagine they are not cheap Im running a set of MSD coils they are easy to find just a bit of wiring is required which is very minor heres the link

Ive been running mine like I stated for two years, and it has a one way valve thats stock on the 7m ISC (its the small washer with rubber that goes between the ISC and the flange) to avoid pressurizing the unit its clean and Ive had no problems
It could also be the cams seals if they leak the oil will come out at the bottom weep hole only wat to tell is to take it apart there are a few other places oil could be leaking as well but if it pours out my guess would be the cam seals.
Did you pressureize the FFIM or the entire system when it was bolted on Ive seen flanges warped causing a similar sound from not sealing properly to the head.
