454 oil consumption (Cherry truck LOOK)

So, Let me get this right. If I put a push in breather in one valve cover, and a pcv in the other it will not work. Tell me again how this is REALLY any different than a system that goes to the air cleaner with the little scotch brite pad? By the same token in systems with low vac, for example race cars, a pcv is the wrong system to run. Crank case pressure is WAY higher than you can pull with a pcv, so you either don't run one (oh my god) or use use some other kind of vac system. Oh and all you silly people air is actually pushed into a vacuum not pulled.
 
Let me say it another way. I love this site but the engine tech is a little questionable. I use sites with much better understanding of the internal combustion engine if I have a concern about the ones I have.
 
So whats the latest? You figure it out yet?
 
Thats cause we are chasing a intake gasket or valve guide problem swaring its a pcv system.

Oh crap, that makes sense! You're not allowed to do that in here! Don't you know you're gonna offend Scott?:rolleyes::haha: I just couldn't stand the poor information about the function of the PCV system being spewed around here, and it dragged me in.:o
 
Well I did plumb it to the air cleaner. I'll drive it around and see what happens.

Moving on though, I'm hooking it up to the leak down tester wednesday morning and we'll see how that goes.

Well it won't stop your burning oil problem (especially since there is no vacuum above the throttle blades). However, you won't have to wipe that oil film off that accumulates on the valve cover around the breather occasionally.

You can learn a lot from the leakdown test. Make sure the valves are closed on that cylinder when you do the test. At least then you can tell if you have ring sealing issues, etc. But if you have an intake gasket issue or something it won't tell you that. Good luck.
 
Everybody get ready to ****. I changed the plumbing as you can see in the pics two days ago. I've driven about 130 miles and guess what, no oil loss. :eek1: I couldn't believe it. I checked it after driving to town and back which is about 30 miles round trip and even at 30 miles I would normally see a slight recession on the dip stick but I didn't see it this time. I continued to drive and check and here it is 130 miles, normally I'd be at least half way down or more to the add mark but it's right on the full. It hasn't moved one bit. I'll be honest with you It didn't make any sense to me either. I questioned Scott just the same as everybody earlier on in the thread. I didn't see any difference between the two other than a smog deal. But pressure sure as **** must have been pushing oil past the seals somewhere and burning it off. The only explanation that makes sense is that by plumbing it to the air cleaner it did create some form of vacuum and relieved that pressure.

Whatever, all I know is I'm super stoked. :D:D

Thanks, Scott
 
Oh no, all my old junk must be using a lot of oil, since they're not plumbed to the air filter. Wait, no they don't.:rolleyes:
Just for sh!ts and giggles, try it with the hose off, but with the new breather on the valve cover instead of the the K&N. If this is really curing the problem, I'm guessing the new breather is restricting the incoming air enough to create more vacuum in the crankcase, not the hose "changing" the circuit.
 
So its not really that he was right its more that you were using junk valve covers and pulling oil into the pvc.
 
Say what you want, but Scott's advice helped the guy...so how about you guys quit being haters? The behavior I've seen in this thread is not what CK5 is about. :deal:

Agreed, but how some of the older members jumped all over Wannaberacing wasn't very CK5'ish either.

Every one on this site has something to offer new or old
 
All I ever try and say is there is more than one way to skin a cat. I have been told I am wrong on this site more than any other and I would put my engine knowledge/experence against nearly anyones.
 
Developing a reputation here or anywhere takes time. Trying to actively discredit someone else in order to make yourself look better is just weak.

There appeared to be some history between Scott and Wannabe, I didn't read every relevant thread, but I do know a few things. First is Scott isn't the kind of guy to tear someone down to make himself look better. Second is there was at least a perception that Wannabe was following Scott around from thread to thread. There were disagreements...and others went out of their way to back Scott up. Wannabe left.

I don't like to see people leave, but it happens. If you guys are trying to chip away at Scott to try and make him leave because you percieve that was what he did to Wannabe, just stop now.

Whether it was a cloggy K&N valve cover breather, or whether it was a plumbing issue, or whatever...the simple fact is when the OP plumbed the PCV system as suggested by Scott the problem went away.

Marty and I are buddies. I have seen Scott argue for pages about things I can prove marty was right about. Everyone has a area of expertise. I don't put people down until people insist I am. Its cool it was fixed so easy, I would have had the intake off already. I was wrong.
