I seen some oil residue coming from my valve cover to my cold air intake. I am assuming this is blow by because their is a bit oil residue within the intake leading to the throttle body, as well as a bit within the supercharger. How did you guys correct this issue? If anyone has had this issue. Thanks!

Lastly, I did clean the throttle body, and sprayed the MAF sensor which did give me alot of improvement in power, atleast the car seems to have alot more throttle response.

 

I made a home made catch can. lol. It seems to be working. Just cleaned it out today cuz it filled up.

Got a air compressor filter from home depot and added a line from VC to intake and thats pretty much it

 

I make an LSJ PCV upgrade with continuous drain back. Not cheap, but functional and does not require draining.


Assuming there are no mechanical engine issues , I believe this system will take care of excess oil in the intake.

 

That does make since! Lol, hmm how much for your setup cause man I think this was the whole issue all along. My air to fuel was all jacked up it was getting bad so today I gave her a good cleaning. I wanna do something so this is not an issue any more. What all did you buy, and a rough estimate?

 

It is worth every penny if it works. How much did you throw out for this setup? I want something because it was a mess..

 

idk...$20? $25 max. lol. the filter was like 10-12 and then the little connector things like 2-4. Hose like 3 and hose clamps. pretty much it. Powells does like a hell of alot cleaner but at the time I just needed something to work without spending much.

 

the problem is, your catch can is filling up with oil. So while it is indeed a cheap and elegant application for you, it may not be giving you the result you are looking for.

 

Yes sir it does fill up with oil. It looked like diarreahh today when I cleaned it out. but like I put in bold in my other quote, I just need something that will work for now without having to spend too much. I am fixing some other issues I have atm(replacing supercharger and stuff) but once I get it all going good I will go back to it and get a real setup.

How much is your setup btw? Would it work with my car?

 

my pcv upgrade is 350 dollars and consists of all AN 6 and AN4 plumbing , adaptors , mounting bracket and hardware, with an oil seperator , which has a removable/cleanable/replaceble filter and check valved out port, as well as a drain back to the engine.

If the engine health is good, and unless there is a faulty check valve in the IM .or a clogged orifice, or gummed up oil separators in the rocker cover, there is no reason for you to have excess oil to the extent you appear to have happening. Some oil will end up in the intake if the engine is run at high revs., or with an aggressive tune. Our PCV upgrade manages these events, but all normal OEM engine components need to be in good order. This is a 2.0 thread, but you have a 2.4, and that has a different rocker cover and different detail to the pcv system. As you have a supercharger on it, I assume you have an LSJ IM on it, and in that case, does the head vent to the pcv valve in that IM?

The normally aspirated non vvt 2.2/2.4 engines really suffer from condensation issues in the PCV and every part of the stock PCV system, including the rocker cover cap, which has a vent in it, has to be in good order. IF you have a normally aspirated rocker cover cap with a vent, that may contribute to your condensation issues.

So to properly advise you, basic engine health checks would have to be done to make sure that all is well with your motor.

Please dont even think about spending money on the PCV Upgrade we make, if any of the things I have listed are not as they should be. Hope this helps.

 

Mine was not bad at all tbh, was just a little bit that jsut had spots in areas from just simply blowing by the surface.. I don't have alot coming out to where im filling a container or anything lol, atleast it does not appear so. So you would beable to get me that whole setup, and shipped to me for $350? Laslty this is a bit off topic but if my MAF sensor is bad will that throw off my air to fuel? because even in 4th gear going 65 mph, and I quarter throttle the gas pedal she bogs down, and is not creating very much HP... and my air to fuel gauge flat lines at 10... so im confused whats going on with my car.. I def need a new tune.. Which I will gladly pay for anyone who can retune it in my area or where ever..

 

For guys that are running a pcv setup that doesn't filter air going into air tract it will lower the octane rating because of the oil being in the air one of the reasons why I'm using my exhaust as a vacuum source

 

if you are getting excessive blowby you have bigger problems powels system is setup for an lnf not an lsj and by him they are 2 completely different systems and you don't want to upset the delicate balance

and you need to make sure that your check valve dosent go bad

 

What happens if the lsj I'm pcv gets stuck open or stuck closed?

 

Yeah so what do i do exactly I am confused now to where to even start lol.. ;/

 

when the car is off boost or the supercharger is not compressing the inlet charge, the check valve in the IM allows the crankcase oil vapor to enter the inlet manifold. When the IM ispressurised the check valve stops pressure entering the crank case. If the check valve is not there, its a huge problem as it leaves a big hole, and the inlet pressure goes inside the crankcase; equally if the valve is coked up and stuck open same thing .

Many of the installs I have seen with aftermarket style vents that defeat the PCV sure have lots of condensation problems - milky oil in the intake.

Some folks manage to do it right. Mr Belvedere has no problems with his set up, so he may be a good "go to " guy for those of you with modded cars and problems.

 

make sure the car is correct mechanically.

 

It is.. So is it just tuning then? I need a tuner!

 

pcv valve in IM is where? lol you sorta lost me in some parts. Which is the rocket cover? Do you mean the valve cover? Like where the hole is coming out? I believe the lsj have that towards the back and mine has it on the front? in that case i had a breather filter there which I swapped out for this homemade catch can. What I got out of the little catch can was milky....

 

Head gasket anyone?

 

I know how the system works but was more curious what literally would happen with im pressure leaking in the crankcase.

 

there is a one way check valve inside the intake manifold

not

if the check valve is bad and not sealing up it would over pressure the crank case and blow the dipstick out along with oil


the problem with the stock system is it isn't big enough once you start moving a lot more air I plug the intake side of the head and run a -10 line from the back of the valve cover through a good air/oil sep

if you have to drain your air/sep can a lot either you put the line in the wrong place or you have a ring problem

 

You are the man sir! Mr B think you can get us some pics of your setup? I think this would some peeps understand the setup a little better. If you would I would appreciate it, thanks a bunch! I wanna beable to make this at the shop to. Thank you sir!

 

that the thing sticking out on top of the manifold? I have my map sensor and boost gauge connected to that. unless im thinking of something else..

 

The valve is in the center of the intake manifold right by the intake ports that mate to the head.

 

ill get ya a couple of pics in a day or 2
