    What got me thinking of it more than marketing is working on some of our 5.3L L83's from silverado's at work. We do some non-standard stuff but the intake track of the engine looked terrible at just 19,000 miles. Additionally, when my barb broke, I saw how much black carbon was getting dumped. Granted, that doesn't necessarily mean it's bad, it just "looks" bad.

    All of it got me to asking questions and all my online research was inconclusive.

    You're on the right track.  It looks abnormal to you so you're curious.  On the Silverados, I'm willing to bet they spend most of the time idling or are used for short distances.  Manifold pressure is highest at idle and low throttle, so the oil vapor condenses and puddles in  the manifold and associated ducting.  The problem with the direct injection engines is just that. Without that injector squirting the fuel at the back of the valves such as in traditional port injection engines, the oil vapors settle on the back of the intake valves and heat from combustion turns them into carbon deposits.

    I broke a PCV barb on my truck today and it got me thinking? Anyone have real info on catch cans? I see how dirty some of the engines at work get, but we do some weird stuff with them. I can't find reliable information that says it's worth it or not.

    The amount of black, dirty crap getting on my intake pipe with it unplugged suggests it could be helpful.

    If they are designed and installed correctly, they work well.   The problem with most kits is they just don't provide enough length of hose for the oil vapor to condense and fall into the can.  Most of the oil vapor makes its way back to the intake and renders the catch can pointless.   The thing you really have to ask yourself is, why do you think you need one?  Do you want to believe the marketing hype?  Cars have been running normal PVC systems for years without issue.  Only recently with the advent of direct injection have we seen issue with carbon deposits being a detriment.   IIRC, you have the Ecoboost, so that is direct injected and you could benefit from a can given it's implemented properly.

    Mazda seems to be trying to slot between what would be the metaphorical Honda AND its Acura variant, but at the Honda level pricing.  With all the work they have done on luxury and materials and less on sport, that is the way it comes across.  Honestly, the new 3 Turbo hatch is almost perfect for a daily driver for me.

    For as cheap as their cars are, the interiors are stupid nice!  I miss my 6.

    I don't have a random orbital.  WAY over due to grab one.  Never did because of the price of the flex.  Have a rotary, but that is overkill for the condition of the boat.

     

    The Griots Boss seems to get decent reviews and is way more affordable.  Any thoughts on what is bang for the buck.  I will use it 1-3x a year max...

    Rotary is fine as long as you use the right pads.

     

    I use the Harbor Freight RO unit myself.  Been running strong for 3 years now.  I think I paid $56.  Really hard to beat.


  5. I don't know if this is the case for all hydrophobic coatings, but I was looking to use them on some stainless canals and pits when I worked at Aramark.  I got in touch with a company who sold a product called Ultra Ever Dry.  They were the industry leader in industrial hydrophobic coatings at the time.  Upon speaking to them, they informed me that if the product is used on a substrate that is submerged in water for a significant amount of time, it actually loses it hydrophobic properties.  They told me all coatings were like this.  They could not explain to me why because of "trade secrets," but said I would never find a product on the market that would last if it was continually submerged in water.    Personally, I am thinking because nothing is truly sealed and everything is porous, then if it's constantly submerged, the water effectively works its way into the pores and under the coating and will eventually lift it.  Just my thoughts. 

    While we are on the subject, I use Scorpion CMX Ion on my gel-coated trailers at work.  It has stood up to the constant bombardment of a 3K PSI pressure washer.  I'm on the two year point on one of our rentals and it's still holding up to bi-weekly washes  on straight gel coat.  I also use it on the thin aluminum diamond plate on the trailer steps and rock guards and it works fantastic!  The front of the trailers take a ton of abuse from road debris, but the Ion handles it like a champ.

    Speaking of Mazdaspeed, I'm thinking of getting a turbo manifold off a Mazdaspeed Miata to turbo my new Miata on the cheap. Already got a better turbo than the factory one. Should be a proper death trap at 200whp...

     

    K swap!

    I thought MazdaSpeed was dead?  That same engine and RWD is supposed to be what will be under the new RX-9 correct?

    You know, their market share is so small, I think they could survive on Speed vehicles only.

    Correct. I tow nothing with my runners and fuel economy is not a selling point. I think the only reason people are buying so many is they are like a lego and build so neat vehicles.

    On that subject with all the groups and forums I belong to that pertain to 4runners, it seems to me that all the wrong people are buying them. A vehicle that is lost in time usually does not make a good fit for people who really want all the new features that other vehicles come with.

     

    All worthless information, but I have not posted in a bit.

    People are stupid and can't appreciate it for what it is.  I am actually dumbfounded how well they DO sell given the "needs" of most buyers nowadays.  Then again, maybe the right people ARE buying them.
