I have a 2012 KIA Forte Koupe with the 2.0 and it is a noisy motor. The 2012 is not DI. The dealer's KIA master tech advised its the cam and valves. I have tried every oil to quiet it down without success. I've used 5w20, 5w30 - both synthetic and conventional. QS Ultimate durability, Advanced durability, Synpower, GTX, you name it, I've tried it. Synthetic does work better. Currently using Kendall GT-1 synthetic with Liquid Titanium 5w30. This oil is the quietest so far. It still ticks during idle. Dealer says it is normal for this motor. I've taken it to 2 KIA dealers - both state normal. I have my doubts, but what can ya do? Got another 7.5 years and about 80k more miles to worry about it.
