S2000 Small Catch Can
By Rob Robinette
The AP1 S2000 has a habit of spitting big blue oil clouds while
on the track in extended right hand corners. An oil catch can will solve the
problem and keep you from scaring the crap out of people behind you in fast
sweepers. The stock engine has a PCV (positive crankcase ventilation) valve that
allows the intake to suck blow-by gasses out of the valve cover. Oil can build
up near the valve and get sucked into the intake where it's burned and turned
into blue smoke. By placing a catch can in this hose you can trap oil and keep
it out of the intake.
For my
catch can I sourced everything from Home Depot. It consists of a small
compressed air water separator (air tool section of the store), two 90 degree
elbows with hose barbs on one end and male 1/4inch NPT thread on the other
(plumbing section), and some semi-transparent plastic hose.
I can't remember what size hose I used so just pop out the PCV
valve shown above and take it to the hardware store so you can get the right
size hose and 90 degree elbows. Find hose that fits the PCV valve, then get the
1/4 inch 90 degree elbows and make sure everything fits/screws together.
The elbows are barbed on one end for the plastic hose, and NPT thread on the
other. The length of hose and mounting position are not critical but if you have
a shock tower bar mounting it there works well. The water separator
has a valve on the bottom to empty the trapped oil.
