Before anybody brings up Makuloco's thread in here, I want to point out that the engine he was working on was out of a different vehicle and not a 3.5EB from the trucks. That engine had other problems that lead to the buildup on the valves.

As I stated earlier, if you believe it to be snake oil after looking through threads and other media, don't waste your money. Honestly, you would have to look at your engine and PCV system to determine if you wanted to do it. Keep in mind that out of all the DI engines out there across all brands, Ford Engineering has built a fantastic motor that does not load up on the valves like the VW and Audi's. Does it happen? Yes, but not to the extent that some people would lead you to believe. It is a fact of DI engines since they do not have fuel spray to wash the valves.

The catch can systems are a system that comes from the racing world. Just like everything else that's crossed the line into everday automotive, they are not for everbody. You have to decide if one of these systems is good for your particular application and if you are willing to pay the price for one.

 

I have one.

I live in CA and we have stupid laws and we have the most strict smog tests in the world. I am trying to keep oil out of the intake to help with smog down the road. If I lived anywhere else, screw it.

its gotten worse since then.

 

That was some good reading.....and now you got me on the fence about getting one. I still can't believe that Ford didn't engineer and implement some way of counteracting possible deposits on the intake valves.

 

Read post 21. The design of the engine is what causes the carbon build up. Ford is ahead of the curve in that the build up is non-existent compared to other direct injection motors.

 

Price aside, does a '14 that is driven as a daily commuter 80 miles, that is used to tow a 1500# boat 3 times a month and a 5000# TT 3 times a year really need a can. Or is it more for the guys with Tuners and a heavy foot?

 

It's really subjective to each owner. If you think it'll help extend the life of your motor and believe it to be a sound investment, then yes. If you think it will be minimal help for the investment or it's snake oil somebody's pedling, then no it would not be worth it. This is one of those mods that is so heatedly debated both ways that people literally attack each other.

Too many can freaks on that board, OP got banned.

 

I have a 14 I run stock in the winter tuned in the summer tow frequently. With a water bottle full every week I check it every Wednesday. Just to give you an idea.

 

If it were a real problem, wouldn't you think Ford would have changed something or added a catch can by now? These engines have been around since 2011, and now the 2015 are out.

I would think that as long as you change your oil at reasonable intervals, all that crap is going to be removed along with it.

 

Good time to say IBL
