Hi,
Over the past few months I have encountered what appears to be oil sprayed on the inside of the passenger side fender well area, along with a fairly good size oil puddle on the concrete under the radiator over by the front passenger side tire. Today I removed the throttle body and noticed how filthy it was. My Trailblazer is a 2002 4x4 LTZ with the 4.2 Vortec engine, and has approx. 157,000 miles on it. I understand that the PCV system is poorly engineered, and has a tendency to let blow by oil collect in the resonator. I may be wrong, but believe the oil reaches a certain level in the resonator, then is blown out around the tube/hose that is located under the front of the resonator.
Questions:
1) If I were to make or purchase a Catch Can, where would I need to splice it in...........Between where the hose is in front of/under the resonator, or spliced in between the short "L" shaped hose on the drivers side of engine.
2) Any plans for making a homemade catch can, or would it be best to purchase one that is vehicle specific......if there is such a thing.
Sorry about scrounging for information on my first post, but I really need to get going on this before my wife returns to work and needs the only spare vehicle we have...........any information would be greatly appreciated.................thanks.
