Hello all I was wondering as I approach 100k miles if I need to change the valve cover gasket and spark plugs ? Other maintenance things I should pay attention to at 100 k? thanks
US sched says 120k miles (or 12 yrs, whichever comes first) IIRC, for plugs. valve cover gasket: unless leaking I’d leave it be, let sleeping dogs lie.
if i recall correctly. i would follow the toyota maint. schedule for your model and year. add egr circuit cleanse, and tranny fluid change. test the 12v.
