Keeping it simple, I took my valve cover off a little over week ago to fix something (my stem seal issue), quickly realized I didn't have the time or resources to get into the engine any further. Put in a new Felpro valve cover gasket and spark plug oil seals and put the cover back on.
In the event that I have a problem with the engine that would be covered in the 10yr/100,000mi powertrain warranty, if a Hyundai tech pops that cover off and sees a replacement gasket, does that throw my warranty out the window?
