Hello guys,
I have a 2012 Hyundai Accent and it has slowly required higher and higher octane to avoid engine ping. I've resorted to some extreme measures. Drilled holes in the intake runners and ran (a lot of) water through each individual cylinder... Sprayed CRC GDI intake valve cleaner directly onto the back of the valves and into the combustion chamber while the coil was unplugged so as to saturate the piston crown and combustion chamber.
I still have ping.
Last summer the CRC treatment seemed to be a godsend. Ping stopped and MPG increased 5 mpg. BUT THE PING HAS RETURNED in the summer heat this year. At first the CRC GDI IVC seemed to help and I noticed a few MPG increase (I would assume since there was less ping, then the knock sensor wasn't telling the computer to retard the timing, therefore increasing the power and efficiency.) But now the car has 138,000 miles and apparently the carbon is just too much to deal with. ...to clarify, I CRC'd it last summer and again this summer. I drilled tiny holes in each runner so I could spray the CRC cleaner directly onto the valves and into the combustion chambers while the engine is running with a brick on the accelerator to bring it up to 3500 rpm. I unplugged the coil on each cylinder that was being treated to keep the cleaner from burning.
...MY QUESTION is... Does anyone know if BG 44K can actually remove seriously carboned combustion chambers?
Obi Wan, you're my only hope...
