Like voodoo said, get yourself a quality catch can on the PCV side. I'm catching quite a bit of oil vapors.No one has yet, but everyone will eventually. Hyundai did nothing to minimize the buildup - no catch cans, no injectors in the intake tract. Catch cans will help some, meth injection will help even more. High quality synthetic oils like Motul, PUP, or Amsoil also help reduce carbon buildup.
it is recommended if you are not using top tier fuel, not needed but cant hurt if you are using top fuel.It's in the manual i believe.
spark plugs are cheap? LOL, not with this car. Each one is 25 bucks- at least for the good ones. plus the labor to install unless you do it yourself.I also have concerns about carbon build up. I'm keeping my car 100% stock because I have a mortgage, 2 young kids and a wife and can't afford to lose the warranty.
With that being said, my plans to at least mitigate carbon build up are:
-use top tier premium gas
-can of Chevron techtron every oil change to clean injector tips
-3K oil changes with ACEA A5 spec oil-for lower evaporative qualities of that oil spec
-spark plugs at 30K because they're cheap and easy and promotes better combustion
Basically, just trying to have the engine running as optimally as possible while limiting the volatility/evaporation of oil that makes it's way into the intake.
Haven't looked into prices, was just going to use OEM plugs. $25 is steep, but at least theres only 4. $100 is still pretty cheap for plugs.spark plugs are cheap? LOL, not with this car. Each one is 25 bucks- at least for the good ones. plus the labor to install unless you do it yourself.
Where did you introduce the CRC into the intake stream--at the air cleaner assembly or further upstream?CRC has their GDI Intake Cleaner, it is an aerosol of PEA and other chemicals (supposed to be 150x stronger than fuel additives) costs less than $ 15 and you spraay into intake before the turbo with engine rinning so it cleans up the turbo blades and the intake valves, they show pictures that it helps break down buildup, I believe that if used before any buildup starts it will keep things clean. ive used it 2 x in 25,000 miles and Ill drop a can of BG 44K or Techron in the tank at every oil change (5,000 mi)
This is a potential problem with GDI
they have a couple videos of using it.Where did you introduce the CRC into the intake stream--at the air cleaner assembly or further upstream?
