Re: Oil Catch Can

IMHO it is a must have for the Hemi V8 but for the Pentastar v6 it is virtually worthless.

I'd love to know what your basing that on. I can't think of a single logic that would put the hemi in any greater need for a catch can than the 3.6, nothing. The hemi isn't DI, in fact neither engine is, it doesn't have any inherent flaws that are known? They both have similar PCV systems.

Give me an idea, I'm always curious.

Also wondering why myself.

Plenty of people with the V6 here have one and collect lots of oil in them after short periods of time.

It is a known symptom of the Hemi engines and has been for along time.

Re: Oil Catch Can

Just in case anyone wants or needs a primer on the topic, these are good short overviews. Take a gander...

Oil Catch Cans | Everything you need to know and more!

https://www.redline-motorworks.com/kb_results.asp?ID=8

Technically beneficial for ALL 4 stroke engines? yes
Will your rig run just fine without one? yes
Should you spend your money on one? Modders and people who think "stock" isn't personal enough, goes on consideration list. The average person, no.

Still doesn't answer the questions as to why it doesn't have any benefit for the V6. We already know it's meant for the Hemis.

So an average person shouldn't want to help maintain the longevity of their engine's health or???? It's hardly just a "personal" touch to add to the engine bay.

Thank you for the links though. Very helpful.

Granted, I don't have one, but have been considering it the more I think about owning this Jeep long term. So the wish-washy answers about catch cans and the benefits for the V6 are getting pretty tired when people have already shown they do in fact collect oil. Proof that it's doing the same thing it does for the almighty hemi.

Re: Oil Catch Can

Should I buy it direct from billet or is there a better place? Is there a code for a discount?

Re: Oil Catch Can

Both of those sites explain nothing about why the Hemi specifically requires a can more so than any other. So far the only supporting evidence is a statement that " it's a known symptom of the Hemi engine". Not busting your chops...
I'm well aware of the Hemi's disposition to send more atomized oil through its PCV system and that Hemi owners love catch cans and find them irreplaceable. I agree that they are beneficial. But just because tons of people buy something doesn't make it a mandate or a reason. Think giant spoilers on tiny cars.
Catch cans are like the republican democrat argument, and even though i know the right answer to both, I'm not going into it. I will tell you this, on a direct injection engine like in my stingray there's no fuel passing over the backside of the valves so oil that re enters the intake can build up on the back of the valve , and with no fuel washing the valve like in a port injection engine, excess oil never gets washed off and over time can create a bad coking situation. Making a catch can a good investment.
Google port injection for a photo, or C7 catch can debate for some amazing tech, and annoying arguments.
Neither the 3.6 or the hemi are DI so they won't suffer as bad. A good fuel injection cleaning at a reasonable interval will nearly nullify the negative effects of oil pass through.

Here it is, over simplified because I'm not an engineer.
In stock format a hemi is more prone and requires a catch can a little more so than the 3.6..... because of a design difference that sends the atomized oil in the 3.6 PCV system through a longer path and in a more winding path before entering the the intake, that allows for more oil to condense and remain in the engine before the vapor enters the intake and condenses into....oil. After all its still just a tube with a one way valve after it leaves the cover. Same as any.
Normal people words... The hemi PCV takes a shorter and more direct path and oil makes it back into the intake, more often..

It's still subjective and engines don't implode without one, I use them but I also clean and polish my exhaust.
