Here are the requsted pics of my supposed "pcv system".. I don't see anything but a bunch of blocked off connections and this silly breather filter. In fact, one port on the passenger side isn't even plugged, which I'm assuming is not normal?? I think I really need to get this guy to fix this system next week!! What do you guys think....??

Here are the pic links... Driver's and passenger's sides...

Again, was there a hole cut to replace the OPS at one time? Did you check?

 

Okay.... Just took the car out and ran her well....both on the highway and hard pulls on the back streets.... When I pulled back into the driveway, I opened the hood and could visibly see oil pumping out of the little breather/filter shown in the pics....!! Enough to cause a significant amount of smoke.....not just a couple of little drops!! I'm assuming from the location, that this filter should more be venting gasses than oil.....
So, my questions/concerns are these...

Should there even be that much oil running through there?? Will a funtioning pcv system fix this?? Lastly.... Does this mean my crankcase pressure is way too high and if so, what does that indicate besides a lousy pcv system?? Other issues?? What do you guys think??

 

Honesty, I'm not sure what I'm looking for as I don't know how what I have differs from stock....I've never seen one. As you can see in the pics, there is this filter and the other end goes into a hole back there that I don't know was stock or cut.... Also, it doesn't even fit flush back there as the metal base is running into the valve cover, so it's just kinda stuck in there at an angle. Does the stock sensor normally go in this hole? Sorry I'm not better at explaining, but as I said, I don't know what the stock system looks like.... The oil free-flowing from this thing definitely concerns me though..

 

PM Me your e-mail address and I will send you some pictures of the PCV Hose routing for your 2001 engine from the service manual.

Seriously...check out the link I posted earlier for ls1howto.com. All the pics you need are there to setup the PCV correctly.

That's not right. It seems the complete PCV system is removed.

 

Wow.....yeah that pic looks totally different from what I have (which is nothing!!) and thanks for reminding me of the earlier post that guided me to the other site. I'm going to look at it, but now I'm not sure if I should just buy the fittings and set it up like the pic or use the catch can system or something different. In fact, I'm not even sure if I can just cap off what he's got for the breather port or not. I'm also wondering why he even omitted it. I can't wait for him to be back from the holidays next week...!!


So in short....... Should I have such a quantity of oil coming from where this breather is mounted?? If it's just connected at the back of the valve cover, it seems like the area under the valve cover would have to be flooded or there is an incredible amount of pressure build-up in there and neither of those sound good.... Even if I install a catch can... At that rate, I would think it would fill rather quickly. For those of you who have them.... What is a normal accumulation of oil in one of those cans?? A couple of cups a week, month, year?? More? Less?? I hate that I don't know but appreciate the inputs....

 

What you have now is no more than a bastardized set of vents that allow excess crank case gasses escape to the atomosphere. Theres not even a oil baffle system under that rear vent filter.

You need to "at a MINIMUM" reinstall the OEM system and see if it controls the blow by gasses. The manifold vacuum thru the PCV orifice, should allow for a very slight vacuum at the oil fill opening when the engine is idling. IF,,, you have pressure or lots of out gassing after the OEM PCV system is restored,,, you have a serious blow by issue.

No,Don't cap the other valve cover. As then it will have no air intake and you could blow your crank seals. Return it to stock unless he has a reason,but I couldn't imagine why.

 

Sounds like unlucky #7........hopefully not.......my guess is......I will be quiet.

 

What is unlucky #7?

 

Stop messing around and second guessing,return your PCV system to stock and I am sure you will be fine.

 

You need to start with putting the PCV system back to stock.

 

Would you guys recommend the stock pcv system over the LS1 to LS6 converson?? It sounded like the original LS1 system has always been a problem and that the LS6 conversion moves the air without moving as much oil?? I was just thinking that since I have nothing and I'm starting from scratch anyway, maybe I should just set it up like the LS6 motors....

 

I have the stock LS1 system with no problems. Some guys have excessive oil blow by with it. Since you are going to have to find the parts for one or the other, might as well use the LS6 conversion.

The main part you would need is the valley cover (50 or 60 bucks). The rest of it is just hose, pcv valve, etc. Do this and get rid of the breather. This will solve your problem and even if it doesn't; it should be done anyways.

 

"Blow by" is a condition of the rings, not the PCV system. Perhaps you meant "oil consumption".

 

Go with the LS6

 

Sorry it took so long for me to repost after you put up the pics. I was in Tulsa at the Micro Sprint Races. I was wrong about the valley cover tube on your car. I thought they had changed it on the 01. Your system should be exactly like the one in the pic from bkel33. It is the same as my 97. You need to do what everyone else is telling you and get the PCV system back in place. A competent mechanic let alone engine builder would not have done this. If you choose to upgrade it you will have to make other changes. For now the easiest way is to put the original stuff back in place. You really only need the original PCV fitting for the driverside valve cover. Some rubber hose T fitting and a stock PCV valve and you are back in business. I personally used transmission cooling line hose as recommended by Ragin Racin to replace the original lines when I installed my FAST 102. Running the Hose is a lot easier than using the stock plastic tubing. You can easily fish it through around the back of the intake. I will attach some pictures of what I did to help you.

I didn't have another 90 elbow that was strong enough to keep from collapsing out of the driverside valve cover so I looped my hose and ran it around the back of the intake. It is kind of hillbilly but I new I was going to be changing things in the near future. Here is a pic of it.[IMG][/IMG]
