Keith Browning Posted February 8, 2007 Share Posted February 8, 2007 I don't come across too many modded trucks but I had a doozie in the shop recently. Failed EGR cooler, no big deal. When I had the turbo off I noticed that the CAC tube and the turbo compressor housing did not have the usual loose oil film rather, it had a thin, blackened, very sticky coating. Obviously cooked oil. My question for those more familiar with modded engines: is this typical of a modded engine that is run hard? I am thinking higher boost and hotter temperatures combined with hotter blow-by is causing this normally oily coating to cook onto the surface. By the way, it had an Airaid intake, 4" straight pipe with no cat and an Edge-2 tuner. I found the Edge owners guide and box in the console.

2003EDGE Posted February 8, 2007 Share Posted February 8, 2007 On the trucks that I have modified, I have rerouted the crankcase vent to do away with the oily film all together. Quote Link to comment Share on other sites More sharing options...
