Goes to crank case.... Oil pan is way in the front.....

hispeed · 01-28-2009, 12:53 PM

ken if i remember, ill snap some pics of my valve cover and give it to you saturday if i remember

*Om1kron* · 01-28-2009, 12:56 PM

well yeah I know where the oil pan is... I read something which I should've quoted that confused me but yes I thought that pipe went to the crank case/bottom end.

No No this guy wanted a pick of the valve cover with the modified baffling... not stock... Thanks!

SILVIA_KIDs14.5 · 01-28-2009, 02:02 PM

what do us s14 guy got to do any thing i never really saw any blow by issues with mine but i could be wrong

*slider2828* · 01-28-2009, 02:05 PM

nah like I said before... slant tops don't have this problem because the crankcase tube already flows into the well designed valve cover (slanted top for a reason) so you just need to probably put a catch can between teh front VC tube and your intake...

Just consider you guys lucky...

*moses* · 01-28-2009, 07:24 PM

This is that restrictor that one guy was talking about. Do you guys know if we need this or not? It goes between the "T" and stock catch can.

I guess you guys didnt catch that this was an S14.3 valve cover, MA motorsports is doing it for a fee. Notice the slant back but no VTC clearance thing up front....

blownmotor · 01-28-2009, 08:00 PM

All this looks like a rerouted version of stock.... If you think about it, it all goes back to the same place except there's a catch can in between it.

4x4le · 01-28-2009, 08:06 PM

haha, I didnt catch that. I was too distracted by the 10 gal catch can lol.
Nice looking valve cover.
I still would get rid of the filter and run it back to the turbo inlet. Your engine is getting some un metered air when the pcv is operating via the filter and valve cover.

*bejota180sx* · 01-28-2009, 08:06 PM

i looked for that restrictor all over and couldn't find it anywhere, i don't know where i put it... its just that a circle shaped restrictor that went inside the hose that goes from the T to the stock oil separator...

if i do find it, ill post some pics...

Yes it was caught.... You still are looking at 400 dollars.... You do it for me for 200 with the two vavle covers I gotta source the cutting and the welding....

If you can do it, then please sell it to me cause I would buy it....

Oh in case you didn't see that valve cover is for sale in the for sale section right now. How much is it, guess what its 400 bux....

Otherwise you aren't adding any help to the thread....

In the stock form all the oil goes back into your intake. In this modification, all the oil is preserved in your motor. It is NOT rerouting the stock way. This also eliminates the probability of any oil making it to your intake....

If by your means stock way then really all SR20's are routed this way with an added catch can.... Same as slanted tops....

The other one you are correct...

Crankcase pressure will always go into your intake because of the PCV valve during idle or cruising in vacuum. Have you really looked closely at the PCV system on SR20's? Your "way" consist of a hose going straight to the oil pan which S13 SR20 has with a seperator between it coming from the T on the valvecover. Also you have a hose from the valvecover that goes to the intake with a catchcan between it which the stock S13 SR20 already does with the exception of a catch can in between. Sounds redundant. Then you go on saying "it preserve all the oil in your motor". How does it "preserve" all the oil in your motor when it's being vented?

Dont know what happen but its there now. Here is another just in case.

*slider2828* · 01-28-2009, 09:42 PM

Wow I have never noticed nor seen that in my life.....

*bejota180sx* · 01-28-2009, 09:46 PM

THAT is the thing i was talking about! my stock hose was damaged so i replaced it, but i kept that thing around here somewhere in case i need it... i've runned without it for a time but i wanted to check if it is really needed...

The stock does not go to the oil pan, it goes to the crankcase, so that is a correction. In stock form, yes there is a stock separator, BUT you are missing that most people run an after market exh manifold, so the separator does NOT fit. Secondly, the stock separator fails to "separate" oil well enough that under 18PSI of constant boost on the track, it doesn't separate oil fast enough, hence I get blow by. Ok I put the catch tank in between the front T and then into the intake, the oil catch fills up. DUH so now I am low in oil, going to spin a bearing and blow my motor. In that exmaple oil that ends up in this catch does NOT return to the oil pan now does it?

My system retains the oil in the engine and drains back naturally. I don't think yo understand how this works.... I believe it has been explained WHY this system was put in place and how it works..... The blow by flows into the VC drains back down into th upper oil pan and the fitting out of the top of the Vavle cover goes into the catch into the intake. No, oil DOES NOT get sucked through the top as this is the 3rd time I have said it, there are baffles in place where that fitting is PREVENTING it fom sucking up oil.

Read the damn thread and not the last page....

*INeedNewTires* · 01-28-2009, 10:17 PM

why dont you run a setup like this.

take out the T fitting, put a regular elbow facing towards the firewall, then run another elbow off the rear fitting on the top of the valve cover. run both of those lines to a T then to one of the catch can's bungs on top. Then on the other bung run your normal vacuum line from the intake. Now for the part thats different. Make sure the catch can is the style that has a drain plug on the bottom like this one and run a line from there back down to the crank case like the OEM rear line just drains to.

That might solve the problem, if it fills up, it will just route back to the oil pan where it can get picked up again by the oil pickup and thus no blown motor.

Or am i just wrong?

Does not your system sound more complicated? Also I gotta weld another bung to the oil pan? That means I gotta remove the pan. Also you do realize thats how the stock system works. So I could have just run the drain back from my catch being filled correct with the most common setup? But the point your system is missing is that the catch will fill at a certain rate faster than gravity, your oil pick up and some sunction that your crank creates will pull the oil from that catch, but still it CAN fill faster than the drain. Remember your system is not running on a dyno, its running on the track where oil flies up due to elevation and side G's from cornering and with 18PSI on the turbo, you WILL drag oil into your intake because of the suction from the turbo. Trust me more trouble than it is worth, because you don't know for certain it will work in all situations.

Remember with the "normal" setup of catch in between front T and the intake pipe, on the street I don't get a drip of oil in my catch... Very different story running on the track, with 245 slicks, high elevation changes like in the picture, 18PSI all day long with on and off throttle, and with a 12/10 spring setup....

blownmotor · 01-28-2009, 10:37 PM

First you shouldn't be getting that much blow by. Even at constant 18psi you shouldn't be getting that much at all. Have you even chacked compression and leak down? I'm running 16psi and don't even get any oil coming out of my valvecover. Looks like a band aid than a solution to the actual problem.

Engine is freshly built as I have said before and are you running on the track or drag? That is a big difference in what you are talking about... We are discussing setup not blowby.... Are you running a 2871R .86 AR... What tracks are you running, does your track have the elevation that I am running on? Is your suspension fully setup? Are you running slicks in long 60+ MPH corner? Are you twisting your chassis back and forth? Dragging down a straight track which sounds like you are doing does not stress the motor as much as on the race track. Come on! This just tells me you are NOT reading the entire thread.... Geezus...

Also I am still waiting on your answer about whether my setup preserves the oil as I have said before?

*INeedNewTires* · 01-28-2009, 10:44 PM

dude if you have slicks, a built motor, 12k 10k, cage, seats, suspension, etc etc etc and your worried about blowing up this fresh motor... then you have the money and are one of the few people that sounds like they NEED an Accusump. just do it already, you will appreciate it more than most, and look like you have the means and know how to install that shit.

BUY ME!

*blu808* · 01-28-2009, 10:45 PM

This is getting way to fucking complicated. I have another Valve cover coming in this week. So everyone just STFU until I can do the mods, take some pics, and post them up for everyone to see. No reason to confuse everyone.

*blu808* · 01-28-2009, 10:47 PM

Also yes. I run accusump on all of our cars.

FTW

*slider2828* · 01-28-2009, 10:48 PM

Mods can just lock this thread..... This is done....

and an accusump doesn't relieve crank pressure. BTW...
