You said it yourself, key word... "PERFORMANCE CAR GUYS". I`m not going to go into large detail here, but on a stock vehicle, oil catch cans are not necessary. I`ve NEVER heard of or seen any proof that oil catch cans will save you money, make your engine last longer, get you ANY increase in mpg`s...etc etc etc. Like others have already said, if you have oil consumption issues far above normal, and/or your engine is using the PVC hose as a drinking straw to your oil pan, you`ve got ALOT bigger problems. I use valvoline synthetic, change it every 4,000 miles, its still on the full mark when i get ready to dump it. So with saying that, i feel the oil catch can is a waste of money to me.

 

Well, what do I know? I see an argument on both sides of the conversation. I don't see how it can hurt and I think ANY oil in the intake is not good. I bet 3" in a catch can won't show anything on the dip stick. Doesn't seem all that expensive to do. I know one of the first things race car owners do is do away with the PVC and put the old breathing tube on. I believe ANY oil in intake is that much too much.Kinda like a K&N cold air intake on my 5.7? Put it on when it was new so I guess I can't say if it helped or not. Many people on here tell me I wasted my money (about $300 as I recall) The stock air intake is pretty impressive. Thoughts?

 

Ah, yes, the filters that are known to let more dirt into the engine and you are concerned about minor bits of oil mist in the intake.

And just for fun, here is one of the many tests that show what a POC K&N and Amsoil filters are compared to the stock and normal after market types

Everbody's right, everybody's wrong. If you like oil of any amount in your intake, cool...if you want nothing but air in your intake, neato. At any rate, no one should have to defend what they do to their truck, especially if there's no harm/downside to the modification. Maybe it helps, maybe it doesn't. I went for it in a DIY fashion for a small amount of money and I sleep like a baby.

 

True, there is no harm - just makes me laugh. Its like talking to my kid about why he does stuff to his Subaru.

 

First, i've NEVER heard K&N filters allow more dirt in the engine. Where do you get that info? Dodge told me they had no problem at all with me putting the K&N filter on. Logic tells me seeing how they guarantee the engine if the filter allowed more dirt in then they would void the warranty. I'm inclined to bet they know as much about it as you or me.
Second, when did I say I was worried about the oil in the intake? Don't put words in my mouth please. I simply said ANY oil in the intake in my opinion is Too much.
Third, as far as your son goes, he probably likes to argue with you, after all it seems pretty easy o get you critisizing someone else! Maybe he thinks you're old fashioned??

 

Oh, so you're not worried about oil in the intake but are worried about microns mount of dirt thru the filter. The finer the filter, the less dirt, the less air, the less efficiency. The air intake on my Ram is deep enough to place 6 stock air filters on top of each other, boy no dirt would enter then right? Of coarse it would be hocked so bad it wouldn't run at all. But then again, there would be no dirt!

 

Did you look at the link?

 

Yes - dirt kills engines, oil doesn't.

 

O'K, I guess after 64 yrs I know nothing!! There hundreds of thousands of K&N filters in use. Like I said, I think if Chrysler honors the warranty, and they do, they probably know more about it than I do.
