Added Oil Separator.
I read this thread and thought that an oil separator was a good mod based on my experiences with previous cars and fouled intakes.
Last Friday I received an oil separator from JLT for my 3.7L. It took 2 seconds to remove the PCV line on the passenger side and install the JLT Oil Separator. For those interested it came with the same type of connectors and tubing Ford used on the original PCV line. Their black anodized version even looks like a Ford OEM part. Sweet!
Well I put close to 300 miles (mixed driving
) on the car this weekend after receiving my JLT Oil Separator. So today I was curious as to how much oil it had accumulated.
A fair amount considering only a few hundred miles of driving. Anyway, these things really work!

The only reason you see liquid oil in the seperator is because it has cooled and collected. Practically speaking, the intake sucks in oil VAPOR which the engine burns off. In a stock engine, it shouldnt collect more than a film on anything unless you dont change your oil often enough. Yet another reason to use a good synthetic oil with low volitility.

Unfortunately not all of the oil vapor does burn off, and the accumulation has been an issue on my cars cars in the past. The real benefit starts after 50,000 miles, when that oil film thickens, turns to sludge, & the build up starts robbing power. The clean up isn't cheap or easy either.

Oil contamination derives from the positive crankcase ventilation valve ( low pressure/high vacuum for positive
displacement blowers) common on most internal combustion engines where vacuum is pulled on the crankcase
by the intake. This contamination occurs when oil vapors exit the crankcase via the PCV valve /vent hose, enter
the intake tract, and create adverse effects such as carbon build-up on valves, pistons, and plugs, as well as
causes harmful detonation. Detonation in many cases causes the ECM/PCM to retard timing, thus creating a
reduction in horsepower.

Of course they work, the well designed ones at least. By removing that oil from the intake, you're getting an effective increase in octane, and if you were boosted, you'd be adding insurance against knock/det because of the effective octane increase. (Oil causes det)
