Call me if you want a step by step check of how you have it routed....sounds like you may not have it right, but it can take a while for rings to seat as well.

So you guys really think that the catch can will fix this. At the rate he is going you can expect to use 7 quarts by 2k, far cry from 1qt in the same distance.

 

i have a breather on teh catch

 

Then you have no good flow through the system.....with a breather on the catch can you release the vacume before it cam evac the crankcase properly.

I do agree that a leakdown would be a good idea just to see if you have a sealing issue.....and where.

 

so how about this?

I run a catch can with no breather to the valley to intake. then put a breather on the valve cover. that be better? or do I need to eliminate the breather thing completely?

 

If your are going to use the breather, then Yes, put it on the valve cover. Run the hose from the valley to the loxer fitting on the catch can, and the hose from your intake to the upper fitting on your catch can. That's it.

 

Definately never said it was going to fix his burning oil. Routing the catch can correctly will fix his first question though.

 

Correct...unless it is our catch can....our inlet is in the center top of the can & our outlet is on the upper side of the can due to the internal design.

 

That's a little uncalled for. We are not trying to give you the runaround by simply trying to help you do what needs to be done to get the rings to seat properly. Should it always take this long? Not necessarily, but there is no catch-all answer that we can give you at this point. This is simply something that does not happen often and there is not a simple answer as to what needs to be done without going through a few procedures to narrow down what is going on.

First things first, you HAVE to address that PCV issue. You have pressure routed to pressure the way it is and that will not alleviate the crankcase pressure at all. You need a vaccuum source ASAP to get the PCV working the way it needs to.

You also need to realize that if you have any blowby resulting from the lack of PCV and excessive crankcase pressure that it will inhibit proper seating of the rings, so there is no issue to address right now other than the PCV, and then getting more miles on it with a setup that may allow the rings so seat better

 

it is not connected the way you tech told me to do it yesterday. We will see how it goes!

 

Did you happen to tell their tech that you were using a catch can? It sound to me like he either missunderstood you or you left that part out. The way he told you to run it, is the way a stock, from the factory, motor is routed...i.e. no catch can. If you run it the way we listed above, and drive it for a while, you should be golden.

 

whoops, i mean it is NOW connected

 

ya same thing really. he said run a hose from the valley to the intake. i just have the catch in between. same thing. we will see how it goes

 

That's alright, there are several ways you can do it, as long as you have vacuum on the crankcase you're getting there. I assume right now you have the valley cover into the catch can, and then out of the catch can into the intake fitting. That's fine, as it's just like he told you but with a catch can in it. If you have a breather on the valve cover it should help that much more. You might still have to do something for a clean air source for the engine as well. I hope you followed Tlewis's link above, it's a great resource for how to make sure the P in PCV is being utilized.

Once the PCV works right it should cut down on any blowby condition which that alone should help your oil consumption issue. Once the blowby condition is cleaned up some miles should help the rings seat properly. :thumbs:

You're on a good track and shouldn't get down about it, it's just minor issues that work together to ruin the experience of a enw engine, it's all going in the right direction with working out little things like PCV

 

You beat me to it, I gotcha, I assumed by NOT that you just meant with the catch can in between. Good luck, and I think you'll find this will all get worked out and you'll be more than happy when it's said and done

 

i meant its is NOW connected like they told me.

I did try a fresh air tube, but on decel, that was pulling oil from teh valve cover into the air bridge. I have a filter on the valve cover. that should be enough.
