On the stock air box too, but you'll need about 21 inch long lines to make that The length of hose and mounting position are not critical but if you haveĪ shock tower bar mounting it there works well. Part of the separator and drain it back into the engine. Has a valve on the bottom to empty the trapped oil. The elbows are 3/8 inch barbed on one end for the hose, and 1/4 inch NPT thread on the Get the right size hose and 90 degree elbows. Valve and take it to the auto parts and hardware store so you can Small Catch Can in PCV Valve Line I used 5/16 inch hose but you can just pop out the PCV Installed in the same location and it works well. I have seen the next size up air/water separation tank
How to install oil catch can rb25det update#
Update 3: The catch can pictured was too small and oil was simply blowing Under normal drivingĬonditions the hose does not collapse and the PCV valve works as intended butĭuring high RPM shifts when vacuum through the line is very high the linesĬollapse and keep oil from being sucked through the line. Inch long pieces of 5/16 inch fuel injection hose sourced from any auto partsĪ collapsing PCV valve line is actually a good thing. Plastic hose pictured ended up collapsing under vacuum so I upgraded to two 18 (plumbing section), and some plastic hose. (too small, see Update 3 below) compressed air water separator (air tool section of the store), two 90 degreeĮlbows with 3/8 inch hose barbs on one end and male 1/4inch NPT thread on the other Unclip theĮmissions legal catch can I sourced most of it from Home Depot. Shut using a large clamp style paper clip while running on track. Simple solution to on-track oil smoke is to simply clamp the PCV valve line
I sourced the vacuum hose and caps at Autozone. Uses 5/16 inch inside diameter hose and the large front vacuum line is 1/2 inch Keeping emissions legal the best solution is to cap the PCV valve and put aĬatch can in the large hose. The other location is the large line that runs from the front of the valve cover This line is the cause of most "blue smoke" problems. There are two vacuum lines that can be tapped for a catch can. By placing a catch can in theĪP1 Valve Cover Baffle Showing Location of PCV Valve and Front Vent Line The engine burns the oil and produces blue smoke. This air along with blow-by gasses and oil are sucked across the valve cover This vacuum sucks air from the valve cover's front large vent into the Throttle butterfly closes during a high RPM shift (or throttle feather) a great amount of vacuum is created in the The higher the oil level on the dipstick the more likely you'll burn oil through The PCV valveĪllows the intake to suck blow-by gasses out of the valve cover. The PCV (positive crankcase ventilation) valve. The S2000 valve cover has a baffle (see pic below) that traps oil near Problem and keep you from scaring the crap out of people behind you in fast On the track in extended right hand corners. minimising plumbing runs, sizes of lines, volume of catch-can etc.S2000 Oil Catch Can By Rob Robinette The AP1 S2000 has a habit of spitting big blue oil clouds while When you start making lots of power – or the engine is tired and in need of a rebuild for that matter – the plumbing of crankcase gases needs more attention (i.e. I wouldn’t recommend option #4 as it blocks the PCV entirely. Option #1 is the easiest while option #3 is the most complicated but will vent slightly better. In the instruction document you sent us, the first three options will work okay for your application and it’s just a matter of which plumbing configuration you want to use in terms of connecting the cam cover outlets to the catch-can. This way everything is still sealed to keep the authorities happy, the PCV setup still works as intended and the catch-can can be put to use to remove excessive oil from the blow-by gases and minimise oily fumes being ingested by the engine from the PCV/intake system. Therefore, when fitting an oil/air separator (commonly referred to as a catch-can) you’ll have to plumb the can in between the ports on the cam covers and the factory PCV valve, to act as a cleansing device of sorts if you will. In order for your car to stay legal it is vital that the car’s standard positive crankcase ventilation (PCV) system works as the factory intended. "Hi Jim, sorry for the delay in getting back to you with this. I actually have noticed the difference, for the good. In reply, I've attached the email sent to me by Cam from TopSecret.
