The inside of my dynamic chamber has a pretty thick coating of what I believe is engine oil, especially in the big square section before the runners. The source I believe was from faulty oil injector check valves which allowed boost pressure along with metered oil to run back up (wrong way) to the dynamic chamber. I could be wrong though, but 3 of the check valves on the nozzles were done.

Having replaced all my oil nozzles, I expect this problem will stop, and my compression should improve a bit. I'm concerned about the sludge in my dynamic chamber drying, hardening and making its way into the motor? Make any sense?

Should I be concerned about this?

 

Wouldnt that just be the PCV?

 

PCV

I doubt that boost would cause any of that since the boost is moving into the engine not out.


I've seen it on plenty of FCs' intakes too. Most N/a. No boost causing that.....

 

So I *should not* be concerned about this buildup in my dynamic chamber?

I just fear like a big chunk comming off and mucking the engine/turbo/cat

 

Well if you have your dc off why dont you just clean it?

 

 

I'm trying to avoid that kind of work. It's fricken caked in there. Thick buildup.

 

Grab some 87 octane and let it soak for a day or two and then get a putty knife and wire brushes. Or have it media blasted
