I don't know if this is the proper forum for this post. If not please move it.
On my '97 and '93 Ford Taurus SHOs there is a secondary intake valve butterfly arrangement. This opens at a higher rpm for more power. The runners in the intake are tweaked for low end power and this opens the second intake valve to the intake manifold and adds power up high.
This butterfly assembly is called an Intake Runner Manifold and gets carbon-ed up badly from the oil ingested through the PCV system. Plus the Surge tank part of the intake fills up with oil.
Recently I have added a catch can between the oil separator between the heads and the PCV valve on my '97 and have been collecting the condensate before it is sucked up into the engine.
I have found that the mixture is ~50/50 mix of oil and water. I now seal off the fresh air intake part of the PCV system and have noticed that the water condensate is almost eliminated. Plus I have 10" Hg of vacuum on the crankcase on the '97 and ~2" Hg on the '93.
Any comments?
