Ordered the standard Bob's Autosports separator today!

The beauty of car ownership is we all can do with our vehicles as we so choose. As a Service Advisor now for the last 6 plus years I have spent more hours than I care to think about educating others on positives and negatives to different systems with their vehicles... Guess it just does not stop for me... There are lots of car enthusiasts here that do not understand some of the systems on their vehicles... Even the ones that have been around long before we were born... While you are correct in a majority of your statement. I still disagree to an extent with it and would not do it to my personal vehicle. But to each there own Brother!

The Text Book is great, but it only covers engines with PCV valves or engines that are essentially sealed, no middle ground, so an engine without ventilation would have the gasket issues mentioned. Breathers are in the middle of the two options and are not covered by this text. Granted they are more suited for boosted engines than NA, but if oil is changed on a regular basis there will be no issues with dilution of the oil. PCV valves were put into place for emissions control mainly and to stop the vent/drain tubes on older engines from leaking oil on the roads. You are right...to each their own.

I'm far from a catch can expert so I have no idea which one is the best. I can only go by my own experience and what I read from others.


I do know that before I bought my 14GT and was inquiring about which catch can to put on my fiancée's 07GT, most everyone said go with UPR. So when I bought my Mustang, that is what I went with and what my fiancée bought for hers. After running it for awhile on my car, I checked the hose at the intake barb and it was wet with oil. I was not happy about that.


After that, I did some more research and a lot of people said go with Bob's so that is what I did. I checked the output hose on it a few months ago and while it was not as wet as when I used the UPR, it did have a film of oil in the hose and on the intake barb. I also used the hose that came with the Bob's can so it was all new and never used. I cleaned the end of the hose out and the inside and outside of the barb and will recheck it at some point.


I do believe the Bob's can is much better than the JLT and I believe it is better than the original UPR version. My UPR can seemed to catch more oil than the Bob's can has so far but that may be because the engine was more broke in when I started running the Bob's can and seems to use less oil now than in the beginning. The new diffuser for the UPR can may end up being better than the Bob's can but who knows.


I would just like to run the most effective can I can but who knows which one that is. Some people base the effectiveness on how much oil a can catches and others on the least amount of oil that makes it to the intake.


I just posted those links so people could draw their own conclusions from the debates on there. I don't run a RX can and only heard that name a few times in the past on some of the Camaro and GM truck forums so I have no idea how good or bad they are. I just thought the guy on there made some interesting points.

I went out and pulled the quick connect off of the intake manifold barb. It's been about 1,300 miles since I last checked for signs of oil. Like before, there was a very slight film of oil on the outside of the manifold bard but it didn't discolor the Q-tip I used on it. I then ran the Q-tip around the inside walls of the barb and only came up with a very slight discoloration. I than ran a new Q-tip around the inside of the quick connect and I did get some oil colored discoloration but it wasn't really that much and the Q-tip was still mostly white. It was more than what I got from running a Q-tip over the inside and outside of the manifold barb.


It doesn't appear that very much oil is getting through so it seems that the Bob's can is doing it's job pretty well.


I plan on reinstalling the UPR can with the new diffuser at some point and see how well it does.

Well, tonight I went out to install my UPR can with the new diffuser. I took the Bob's can off and pulled out the quick connects from the hoses.


Looking into the end of the output hose that I had just pulled the quick connect out of, I saw no oil at all. It was completely dry. I looked inside the barbed end of the quick connect that had been inside the hose and ran a new Q-tip all the way around the inside of it and it came back completely white. No discoloration at all. I'm not sure what to think since I did get a slight discoloration on the Q-tip when running it inside the quick connect end. Maybe I forgot to clean that side out when I originally installed it. Maybe it's working even better than I thought.


I did drain the Bob's can and I had 1/2 ounce of oil in it in 1,300 miles. The oil didn't look like it had any water in it at all.


I ended up not installing the UPR can because when I went to mount it, I discovered the problem I was having before. The bottom of the can hits the coil cover and actually wore part of the knurled section on the edge of the can smooth and also wore a spot on the cover itself. It also rubs on the AC line that is there. I'm going to talk to UPR about making a bracket that holds the can up higher so it clears both the AC line and the coil cover. The Bob's can doesn't touch a thing.

Good to hear...

I've posted this in a couple spots already, but I installed my Moroso with 25 kms/15mi on the car yesterday. There was already significant oil in the stock PCV line. Apologies for the bad cell pics...





I haven't driven it with the catch can in place yet, pretty much been thunderstorming since I picked the car up yesterday. Got the can and a few other things on.

How's the MOROSO working out???

lakeguy77

It looks great!

Was thunderstorming or just plain pouring all weekend so have barely driven her.

I actually did end up mounting my UPR can before my trip to Texas last week. I just got back today. I used the mounting bracket off of my Bob's can to mount the UPR can and it held it up high enough not to hit anything. Here is a picture of it mounted using the Bob's bracket.





I drove a total of 1,207 miles on the trip. Unfortunately the new diffuser and taking the SS mesh out of the output side of the can like UPR recommended, did not work to keep oil from making it to the intake. Here are a couple of pictures I took after I got home.






I also drained out the UPR can and got 5/8 of an oz of oil out in 1,207 miles vs the 4/8 of an oz of oil out in 1,300 miles on the Bob's can.


So it seems that the UPR catches more oil but still doesn't prevent oil from getting to the intake.

What all fittings and accoutrements did you go with to make it all work? Mind sharing price, this looks like a competitor to the Peterson can kit from Rehagen.

Bullitt 3309

This is the parts list:
Summit:
Fragola Performance Systems AN to Pipe Thread Fittings 481611-BL – 2 ea $4.97ea
Fragola Performance Systems Series 2000 Pro-Flow Hose Ends 220110-BL – 2ea $9.97ea
Fragola Performance Systems E-Z Clamp Hose Ends 280210 – 2ea $6.97ea

Ebay:
STAINLESS STEEL/NYLON BRAIDED 15KPSI AN10 BLACK OIL/FUEL LINE/HOSE FOOT/FEET – 3ft - $15
The can I used will not fit with the battery in place, where as the peterson setup will work with the battery in stock location. I moved my battery to trunk

Brandon302

There isn't enough room to put the can closer to the heads?

Sir... I have a Bob's can right now, and used their basic hoses and clamps. I would like to use SS lines just like yours, to go on to the Bob's fitting or anodized fittings, and into the pcv connector. Would these parts you have above work for my application?

Kudos to Ford for building our monster Coyote motor without direct injection. The real problems with blow by oil buildup developed with early direct injected motors due to the blow by oil not having treated fuel to clean the intake any longer. Most manufacturers of direct injected motors have added very sophisticated separators.
And that is why separators are a good solution for us as well. Not as critical for our Coyote but helpful.

What do you mean unless your supercharged ?

You should have both then...
