I have a general question regarding a timing chain life interval on the Koups 2.4L. MPI.
I was so paranoid about the 2.4L self distracting, that I had tunnel vision regarding "ticks" knocks or anything abnormal sounding. I scheduled a appointment at the Kia dealership on 2nd day of ownership to have a couple recalls addressed, and to have on file this non concerning "tick" sound incase it were to get substantially worse. Kia gave the engine a "perfect" bill of health, and even went as far to say "its one of the better ones"....
Fast forward over 50K miles (over 15 full syn oil changes with absolutely zero oil consumption during any OC) I have came to realization that the engine its self is not ticking but rather the timing chain that has a tick at around 1950 rpms, but only when there is near zero/super light load on the throttle such in parking lots while in 1st. I can also hear the sound in 2nd and 3rd, but again the rpm range for the sound is very narrow.
Over the tens of thousands of miles the tick sound is actually disappearing, and the engine itself seems to run better and better with every passing oil change... BUT I believe if there is any abnormal sound that means something might be wearing incorrectly, even though the tick has never gotten worse and is actually getting better, I have a hard time believing it "fixed" itself. I will add this, I removed the under hood liner for the CAI setup sometime ago so every sound of the engine is amplified.
I starting looking at replacement parts to feel it out - oem/genuine and the replacement procedure in the factory service manual, and tbh looks like I could do the whole job for a couple hundred dollars in the driveway with no real special tools needed... I am seriously contemplating changing out the timing chain for piece of mind and for a financial "cushion" so to speak incase if something in the timing chain system were to fail and ruin the engine, as the 2.4L engine itself is a few thousand dollars.
I am aiming to run this original Korean built 2.4L MPI engine over 250K, with a 300K mile aim, (and zero car payments) while doing so. I am closing in on 180K at the moment.
Would this be a wise idea at the end of the day, and would there be anything unexpected while doing this repair? I would not mind changing out gaskets or any other "wear item part" also while in there if I could access them.
Thanks for the feedback.
