I just posted this in another thread. I had about one ounce of oil in my catch can after driving only 350 miles. I will let everyone draw their own conclusions of the effectiveness of catch cans.
Hey,Just checked catch can and WOW only 3k miles and almost halfway full. Don't wanna say brand don't think they are a sponsor and I know there is a sponsor that has them. Any catch can is better than nothing. This was with no extreme angles this round.
Do you have a parts list as to what you actually purchased?I am willing to bet that a catch can will prolong a spark plugs change or fuel injector am I wrong?
Update: my JL has 1300miles on it installed a catch can was not so hard I manage to get a good amount of oil with a 120mile road trip. I did went the cheaper route and ended up getting a catch can from aliexpress. My predictions were true it's exactly the same can mishimoto uses but for just $16 bucks. I did have to make my own mount and buy the lines. But ended up getting better lines and better fittings then what the mishimoto gives you. Total price under $50 bucks.
Catch can from eBay. OPEN it up and check for metal shavings from manufacturingDo you have a parts list as to what you actually purchased?
Yea mine is the same, looks like we have the same catch can. I change the catch can probably around every 1,000ish miles and it's the same.
Dealership will tell you its normal, don't waist your time. They say the new valves are built for blow by.
I'd say check it more often and enjoy the peace of mind!
I agree with DI argument, I bought the Jeep for two reasons, 4 x 4 capable and non DI engine which is pretty rare these days. I owned a VW GTI with intake DI issues, I vowed not to own another, I did trade in a '17 Tacoma with dual injection which seemed okay but didn't own it long enough to experience rhe typical problems.In my opinion, the catch can on the 3.6, won't do any harm, but is not really needed. Because it's port fuel injection, any oil vapor that gets into the intake valve area from the evap system gets washed by the gas which flows over the valves.
On the direct injected 2.0, its a different story all together. No gas washing over the valves. The vapor just sticks like glue to the back side of the intake valves. I think a catch can is very beneficial on any DI engine. Now, warranty issues will ensue if the dealer sees the catch can.
