Intermittent Drivers side Valve train clicking... 96 4Runner LTD 3.4L 230k miles.
Ok so I've recently been noticing some intermittent ticking/clicking valve train noise on the drivers side that is not your ordinary valve train noise. It's really strange... it comes and goes. Also seems to fade if not disappear if I manually idle it up 500-1000 rpms. I know these 3.4L engines are damn near bullet proof. I've owned many Toyota's with this motor with zero issues. My 4Runner currently has 229,500 original miles on it and runs strong! The internals are super clean... I've always ran top notch Amsoil 100 percent synthetic 5w30 and Amsoils EaO series oil filters. So I'm pretty sure it's not a lifter sticking.
I can't recall if the valves on these 3.4L engines are adjustable or if their hydraulic lifters?
Any help and or suggestions on this issue would greatly appreciated!!!
Thanks a bunch!
