The pump didn't have anything to do with it. These ICs are failing from stress fractures in the core due to the inherent design flaw of the core and repetitive heating and cooling cycles.

Right now, your options are either another OEM one from the dealer that will eventually fail again or the upgraded one Speedriven and I put together. The thread is located here: https://www.crossfireforum.org/forum...-got-real.html If you're interested or have questions about the upgraded IC, shoot me a PM.

As for the upper plenums, nothing sucks worse than having to clean all that crap out so good to hear you have a catch can to keep it all nice and clean after you clean these out. Best advice to clean them is with a high power pressure washer followed by new parts washer solvent or shoot in a can or two of brake cleaner and swish it around in there. If you don't get everything out with the pressure washer, you can leave them in the solvent over night but i wouldn't leave them in longer than say 8-10 hours.

Take care
