catch can and pcv vent on DD

[GIRman67]

Think I'll go that route

Like I said I'm not expert so this idea may not work how my mind thinks it should. I just made a revision might be easier than the other.

If anyone has ideas on why this will not work or is a bad idea chime in. I'm not perfect and these ideas may not work at all. So don't take these ideas as gospel.

please leave comments on which you think would have a better desirable effect on least amount of oil going through the works

Here is mine. I Added a port for the pcv because mine is still in place. It works pretty good.

the weep hold never goes into the inside of the valve cover, it passes through into the sparkplug wire area if you have oil coming out the weephole in front then that means its filling up where your plug wires go or that you have a crack in your valvecover

Those little holes do go through but most people have great ring seal and working pcv systems so they don't leak. Try cleaning the pcv valve and se if thats helps.
It seems like 1 out of 100 oil catch cans I see are actually installed right. Who cares if a little oil vapor gets in the intake pipe. You should have that stuff off every oil change anyway to clean the maf/filter/intake pipe. It should go between the pcv valve and the IM so it don't get gooey. The idea is to keep fresh clean air (intake) in the crank case while corosive gasses (blowby) are being pulled in the IM and burnned off. By only venting the VC you will not have any vaccum constantly pulling out the bad and drawing in the good thus contaminating oil faster.

Do it the way i did it, minus the top of valve cover fittings...


This shows my custom catchcan, (2) inlets on top, (1) outlet on the side.

(1) outlet line runs to turbo intake pipe..


Easy and simple.

As nice as this set up looks couldnt you just replace the pcv with a nipple and run the hoses from the factory outlets on the VC to the catch can?

For all of you wanting to know, I am drawing air FROM the catchan with my Intake pipe with a 1/2" hose, picture #2 shows the hoseclamp and hose, and the air is then being drawn through my catchcan ports that are going to my VC...

so as im even just cruising my intake pipe is drawing whatever air it can find in the crankcase, so good in fact when I took the hose of the intake and sucked through it, it would hold vacuum until I pulled my dipstick out and fresh air would start to draw through.

Also when in boost your intake pipe is under decent vacuum (air entering turbo) and i should never see any blowby thats too much for my intake pipe to suck out...Make sense??

If you have an intake pipe, Thats the way to go, Plumb your valve cover breather, and PCV breather (get rid of pcv valve because intake pipe never sees boost) and route those to a catchan, and then have your intake pipe drawing off your catchcan. So if you have an Intake pipe, instead of venting, just run the hose to it.

Make sure to have a catchcan though, just running your breather/pcv to the intake with no catchcan results in oils entering your turbo and sludging up your intake manifold overtime.

For all of you visual people, Heres how I explained it for my buddy.

If you want to go the easy route, tap both the valve cover breather/ pcv port with an 1/8th pipe tap, go get some 3/8" barbed to 1/8" pipe fittings, run the 3/8 rubber hoses (autozone) to your Catchcan, and do the same but a 1/2" line to your intake pipe..So now you have one 1/2" hose drawing through two 3/8" hoses. Pretty unrestrictive.

P.S.- Sorry its on paint, i could've done it on CAD but I use that program every day for work so anytime I can get out of using it im down. , also if anyone wants some tips on how to make a scavenge effect CC, i can give you some tips, I fully tigged mine with stainless sheet/ and also, Yes I plan to DD this car for a while, This is a Proper set-up so I am not worried.

Here is the idea i had i used your drawing but modded it alittle to show what i am thinking of doing on mine. Everything is done on mine except fot the electric vacumn pump part I am goin to the salvage yard to get one off of a 98 lincoln. they have them in the passenger side fenderwell. $20 part

instead of drilling and taping any one just run a catch can off the factory valve cover outlets? maybe just take the pcv valve out and put a nipple there.

sorry brainfart Im doing a bad job describing it, when I say put a nipple there I mean put this in the place of pcv-valve.

I think I'm gana give it a try, I don't see why not. Anyone ran this set up who can chime in?

That's what I meant to do, I said in one of the posts that to do exactly what I did, you would have to completely remove your baffles. To go the easy route, I said to go grab some 3/8 barb fittings (which are nipples) in the stock pcv hole, and also tap out the VC breather and put a 3/8 barb fitting in there also.

Then you can just run rubber hoses to a catchcan. Easy and cheap.

Youve got the idea right though.

I since have just bought a new Valve cover, welded on -an bungs and am now using -8an braided hoses to my new Aluminum CC i made with a little bit better design. It will be sent out to Tirado for Powder very soon.

If anyone needs the design of the Catch-can I used, I have plenty of CAD files I would be willing to share.
