im going to order one, but for the V6 it seems to be limited. i found AM has the JLT. bobs oil doesnt seem to have a V6 model.

im curious why people hate it?

thanks

They've been known to cause vacuum leaks leading to a lean condition. And they don't trap as much oil as the others.

Where does the leak occur? I guess at the intake manifold for it to cause any type of lean condition. But wouldn't the map sensor notice this and inform me if there's a leak?

I'm just concerned because I have a JLT catch can and want to avoid any problems with my car. I drive it pretty hard on a daily basis and really don't want any problems.

The old style ones didn't collect a lot of oil. I've heard the newer style ones are significantly improved but I haven't been able to test one.

I'm happy with mine and it seems to be doing its job. As I mentioned in another thread, I'm getting some blow by on the drivers side.
As far as leaks, some were not getting the crimp clamps tight enough where the line connects to the can.

That's what I wanted to know. Thanks for your input.

I've had mine for well over a year now and have had no issues, but I didn't know that public opinion had changed on these things. When I bought mine, everyone recommended them (JLT). I empty it at every oil change and it's usually about 1/4 of the way full. Seems to be doing its job!

The link worked for me. Maybe this one will work.

That's interesting, I check my jlt catch can every month or so, and it's usually about a qtr full at that point. Thats about 800 to 900 miles a month. I think it does depend on how hard you drive your car. Higher rpm = more oil?

I have one and ordered some alluminum connectors from JEG's instead of the other ones. I also used the regular style hose clamps so I know they aren't going to loosen and cause the vacuum leak. I didn't use the stock hose and used some 5/8" hose instead.

I think mods, driving style and climate all play a part in the quantity one gets. I guess I need to keep track of mine everytime I empty it and see how much I get per 3k miles.

I had recently added JLT to my V6. Its been about 500 miles on it now. And after going through the video from previous post. I was curious and went back to check and indeed JLT was doing its job, Had at least a table spoon oil in it. I think Bob's is a good product with a bigger container. That is why it holds more oil.
My Conclusion: JLT is not bad but its just has a smaller oil container. I may be wrong someone can pitch in maybe.

What you guys need to remember though is this, it's not just about how much oil the can will catch but how much gets past the can. While you can't really measure how much gets past the can but you can get an indication of how effective the can is by how much oil you see in the hose at the intake.

Both myself and dbmichaels did a comparison test of some catch cans where we put them in series to determine how much was captured in the second can to see how good the first can was doing. Do a search of our username and you should be able to pull it up.

Using myself as an example, I'm currently running a Bob's can which only leaves a very slight oil film in the exit hose. Two different versions of the same manufacturer of cans that I have tried on this car left liquid oil in the exit hose. This tells me that the Bob's can is doing a better job of catching oil than the other ones I used.

The bottom line is the amount of oil caught is just part of the equation.

Unfortunately it seems that for v6 owners such as myself, JLT is really the only catch can available. I do notice some oil on the exit hose but it is also catching a good amount so any help is better than no help :-/

I don't think JLT oil separators are BAD!
Just others seem to do a better job ( Bob's , Moroso)
If you want to know if it is doing its job, check the hose coming out of it by the engine, run a Q-tip in the hose
My moroso after 8,000 miles had none!
But any separator is better than nothing!
Oil residue in the intake track air causes a loss of obtain, and can cause deposits in the cylinder head! All of which robs power!
Oil separators don't make you more power they just keep you from loosing power!

I had a JLT which was in service for 22,000 miles on my 2012 V6. It caught an average of 1/4 ounce per 1,000 miles and I didn’t have any problems with it. I forgot to check it during a 6,000 mile round trip from San Diego to Miami and it overfilled.
