Hi trying to replace my pcv valve (cleaned it, but it's letting air pass). ordered one online, ordered one from a store. Both have a red gasket and the threads are longer than the current valve. Doesn't seem to seat properly. I can't find the blue plastic type pcv valve that came with the...

I have a 2012 optima ex 2.4. The check engine light came on with about 94,000 miles. Shows code P0444 which is purge control valve. I replaced the valve and the code returned within a few days. My first thought is to try another valve just to make sure the new one wasn’t defective. What do I...

What up guys, Installing a Greddy BOV and wanted to know if anyone had any tips. I've been researching the heck out of it and have seen some different things I hadn't heard of before. Every other BOV I've installed was pretty much just plug and play. But I've read about "Spring Mods" and...

Good day gentlemen, I have a 2013 Optima EX turbo that is driving me crazy. Firstly I am a tech and at a loss why my 2.0T is experiencing engine vibration at idle. I am well aware of how GDI motors operate but this vibration is becoming more violent as time goes on. It has already been to the...

I read an Interesting article about GDI engines intake valve deposits, The author of the article said that detergents and cleaners that are added to gasoline have (almost) no effect on preventing or removing intake valve deposits in GDI engines. So adding products like techron fuel system...

I know there is a thread discussing this under TSB's but I have a totally different question. There is a voluntary service campaign for 2012-2013 Optimas that involves reprogramming the ECU to reduce wear on the "Flow Control Valve". Does anyone know where the "Flow Control Valve" is located...
