    OME and worth every penny.
    What car has a 3.4?
    My truck from TX has a cooler. While it doesn't look substantial. maybe it's the sole reason these engines last a long time.

    O.P: Have you looked down below the belts at the front of the engine? When my crank and cam seals leaked, it dripped down ON TOP of the oil pan, and then proceeded down and aft from there, all the way to the sway bar and rear of engine. Photo below is the spot I'm speaking of.

    Hey OP did you find the source of the leak? I've been reading around this site for weeks trying to diagnose the problem. Replaced Valve cover gaskets, took into a shop and advised it was the cam shaft plugs (forgot to do those when replacing the gasket) and still have oil on the lower portion of the bell housing, also on the rack and sway bar. Let me know!!

    My 02 3.4L V6 is leaking oil big time. Just did entire valve cover gasket replacement AND timing belt only a month ago. I’m hoping it’s not the RMS. It’s all clean on top, but way down underneath and all over the entire underbody is soaked. Oil filter - a Toyota filter- is nice and tight, plug is secure.

    try using at 205 on your next oil change. Worked wonders for me.

    Put a jdm motor in it, you can do all the work on a motor stand and have a fresh engine. Except the install part that's a lot of miles
