PCV line "Camel filter" mod I prowled through Pep Boys and found an air filter for filtering the PCV line. The filter is a small acrylic bottle, filter and separator used in an air compressor-line for spray painting. It cost $19.95 and is a Camel 56-100, without the automatic drain, so it has a small manual drain at the bottom of the clear acrylic bottle. It is designed to filter solids AND liquids from air, so it should work better than fuel filters designed to sperate solids from fuel.
The actual filtration is through a tiny 3/4" tall replaceable poly filter and the acrylic container is about 3" tall and 1 and 1/2" in diameter. The oil seperates into the bottom.
I also bought 2 brass 3/8" fittings that are made by Camel and sold alongside the filter, and a brass 3/8" splicing fitting, and some screw clamps. The Camel filter with auto drain has the same part # (?!?) and I doubt if this would work in the PCV system, so be sure you buy one with the black plastic screw and thread lines that show through at the bottom.
When full, the acrylic container will hold maybe an ounce of oil. I temporarily mounted it with cable ties to the A/C condenser so I could see it and drain it. I used an extra 30" of 3/8" gas line tubing, spliced into the existing line, which I twisted 180 degrees over to reach toward the new filter.
After 150 miles the filter has collected a tiny barely visible amount of oil. My '98 car never did ping but I was interested in the filtering the PCV line after reading Steve Hovis well-illustrated website about PCV filters. Oil has no octane rating and collects in the throttle bore. Steve, thanks very much for the concept. Anyone with pinging should try this "Camel filter" mod. It should result in a slight increase in octane for anyone though, and it is super-easy to do, in about 1/2 hour, for about $30.00 total.
This mod accomplishes more than a new PCV valve because it is an actual filter, and does not cause a reduction in air flow, which I suspect is all that the new GM PCV valve does.
I would not be surprised if someone else has already tried this, but I had not heard of it and thought others would like to try it out.
