Oil definitely comes out of the PVC valve and is being sucked into the plenum. I have a home made catch filter installed in-line between the PVC valve and plenum intake, it has been collecting oil for the past 2000 miles. I'll post a picture later. I'm not sure if there are any other paths that the oil could take to make its way into the the intake, need to read the service manual.

Here is a picuture of my oil filter (I know, it should be black), not pretty but very functional. I'm not into dressing up my engines other than trying to keep it clean. The filter is a mini air compressor water and oil seperator with 2 3/8" barbed fitting threaded into it. Total cost is around $15, can't beat the price and it is extremely effectively. Just need to empty it at every oil change (all depends on how hard you drive). The amount of oil you see in the picture is a around 1000 miles, not much at all.

Mustgo,

Here is the parts list:

1. Campbell Hausfeld mini filter available at Wal-mart for $11, see picture below.

2. (2) brass fittings from Home Depot (1/4" NPT on one end and 3/8" barbed on the other), around $3.

3. 3/8" I.D. 18" long rubber tubing and 2 hose clamps (I used black fuel tubing), around $2.

4. Plumber's teflon tape.

5. 2 tie wraps.

Assembly steps:

1. Wrap teflon tape around the 1/4" NPT end of brass fittings and thread into mini filter.

2. Remove engine cover and disconnect both ends of existing hose coming out of PCV valve. REVERSE this hose and connect the end that went into the plemun back onto the PCV valve. This hose should now stick straight out of the PCV valve and away from the engine (see picture below)

3. Slip a hose clamp onto open end of hose and install mini filter. PAY ATTENTION TO THE ARROW INDICATING FLOW DIRECTION OF MINI FILTER, ARROW MUST BE POINTING IN DIRECTION TOWARDS PLENUM. Purpose of PCV valve is to vent engine gases and oil vapors back into intake to be reburned.

4. Place 2 hose clamps onto the 18" tubing and connect one end onto the mini filer and the other into lower plenum. (trim hose length as required to minimize slack)

5. Secure mini filter with tie wraps to nearest cable bundle and you are done. Empty filter as required by unscrewing polycarbonate sight bowl.

Hope this helps.

good info.....

in order for me to add this to the library, i need more info please.....

lets review.......

1. Wrap teflon tape around the 1/4" NPT end of brass fittings and thread into mini filter.

what is NPT?

2. Remove engine cover and disconnect both ends of existing hose coming out of PCV valve. REVERSE this hose and connect the end that went into the plemun back onto the PCV valve. This hose should now stick straight out of the PCV valve and away from the engine (see picture below)

where (in a file photo, or new pic please) is the pcv(?) valve

3. Slip a hose clamp onto open end of hose and install mini filter. PAY ATTENTION TO THE ARROW INDICATING FLOW DIRECTION OF MINI FILTER, ARROW MUST BE POINTING IN DIRECTION TOWARDS PLENUM. Purpose of PCV valve is to vent engine gases and oil vapors back into intake to be reburned.

excellent!!!!

4. Place 2 hose clamps onto the 18" tubing and connect one end onto the mini filer and the other into lower plenum. (trim hose length as required to minimize slack)

another pic, as installed, is needed ((please))

5. Secure mini filter with tie wraps to nearest cable bundle and you are done. Empty filter as required by unscrewing polycarbonate sight bowl.

excellent idea, with cheap and easy maint. access!!

if you can find some photos, or i will take some pics of the oem setup ((point me to the pcv valve)), then we can get this hopping....

also, for reference......

this mod is for OFF ROAD use only, and may void your factory warranties, or extended warranties... Please check your local and federal laws, where applicable.........[/quote]

+++++ i have moved this to the temp section, until we can mainstream this install..... please PM me if you need any photo help, but i really think some 'undercover' shots will be needed to complete this, without alot of questions...

I can help a bit (I think).

NPT - short answer- Geeky plumbing terminology. Ask your friendly Home Depot employee for it and act like you know what you're talking about.

NPT - long answer (will likley raise more questions than answer): a quick google search yeilded the following:

IPS: (Iron Pipe Size) Standard Pipe threads. Female IPS is internal pipe threads, male IPS is external pipe threads. Also known as "NPT" or "NPS".

And

Port — an opening or passageway for the inlet or outlet of
fluid in a valve. The terminus of the port is threaded with
National Pipe Threads (NPT) to accommodate line
connection. A port designated with an NPTF port indicates
one with dry seal threads. A port designated with a PTF
indicates one with short dry seal threads.

:shock: Plumbers must be smarter than I thought.

Oh.

Well that would be the threaded part that screws into the filter. The teflon tape helps seal it up.

More picuture to clarify the install:

First picuture shows the filter with the brass fittings installed. 1/4" NPT (National Pipe Thread) is a standard tapered thread profile used in the plumbing industry. MAKE SURE TO WRAP SOME TEFLON TAPE AROUND THREADS TO PREVENT LEAKAGE. Exposed ends are 3/8" barbs.

So, I picked up the parts for this today. In looking over the filter, it has a label on it that reads: "Avoid synthetic oils, chemicals, solvents, paints and fumes which may cause bowl failure." :? Comments?

Mustgo,

I have not had any issue with the plastic bowl reacting badly to synthetic oils (Mobil 1 5W-30). The filter on my SC400 is a few years old and no problems at all.

OK, cool. I use Mobil 1 as well.
