Got my oil changed at the dealership in my '06 Ram and found this under the hood just sitting on top of the radiator..?

 

Goes under your oil cap, the end with the hole sits up.

 

Wow, really? Goes down into the fill tube? What purpose is it there for and why did the tech pull it out and leave it on my radiator?!

 

Why he left it out, I'm guessing airheadedness, mental retardation or just plain carelessness. Goes like this:



It was band-aid fix TSB because the 4.7 has always had emulsion/condensation issues, which seems to be a common theme with the newer engines with those high fill caps (my hemi has it).

will help to reduce the amount of oil emulsion accumulation within the oil fill housing.

cloth.

 

Interesting since my Ram is an 06 with the V6...musta been set down on mine by accident while the hood was up. Seems that this thing is obvious when installed so I would have seen it the times I changed the oil myself..

 

They take it out so to use a pump gun or funnel with ZERO restriction. That piece restricts flow and makes a mess if you fill too fast. Allows you to dump wideneck oil bottles down super fast with it removed. I dont have one on my '08 and oil goes down super quick.
It's there more or less to prevent get this... the "sight" of oil emulsion, what we know as sludge. It's a ridiculous remedy to mask an emulsion problem so the customer cannot see the issue, thus making them feel better.
The things they come up with are unreal. Leave it out. It's pointless.

 

Your V-6 is a derivative of the 4.7 (3.7 = 4.7 - 2 cylinders + more stroke). My wife's Liberty had it and my Ram had it (had to look up a pic online since I couldn't take one for you).

X2

 

I knew the 6 and 8 were brothers but wonder why the TSB didn't include the V6 and only mentioned the V8. Either way I thank you for the answer. Now I wonder if anyone would actually buy this thing on Ebay....!

 

Because the TSB is dated 2000, about 2 years before the 3.7 was available...
