Good morning,
I own outright a 2013 Hyundai Elantra GT, 1.8LNu port injected 4 cyclinder w/ 78k miles. The oil has always been changed every 3500-3700 miles either by a hyundai dealer, private shop, or myself. I'm unable to provide proof of every change but if anyone were to pull the valve cover or oil pan, it would be clean and sludge free. I have a 10 yr/100k factory warranty.
I cannot tell you exactly how long ago I noticed this loud noise, which is more pronounced when the engine is cold. This engine has always been "chatty", which I contributed to valve train noise and the thin oil it's spec'd for. There is a distinct knock noise that I believe started around 60k miles. Car runs great and has been problem free. I consider myself a spirited driver, and frequently take advantage of all 6 speeds.
Dealer told me over the phone that piston slap isn't common and they will diagnosis it for $125. A quick google search infomed me that a TSB was issued for Canadian cars within my model year, and same engine, and short blocks were to be replaced on Hyundai's dime. The Elantra GT was all built in the same factory. This TSB wasn't issued in the US, and it appears that people have fought/class action lawsuit to address this very same issue.
Below is a video of my car, running when cold. I hear two distinct sounds- a knock (louder, more solid sounding), and valve chatter (higher pitched chatter).
Thoughts??? Advice?
