    Just changed mine out, successfully. Thank you for the video. It was very helpful. If anyone cares, the torque value for the #1 timing cover bolts is 80 inch lbs. And I was able to do it without removing the lower left bolt on the timing cover. It's the hardest one to get out and back on. But if you are careful, it doesn't need to be removed. Thanks again, great video!

    Couldn't get new washers in my small town. The mechanic at the auto parts store said look at the washers closely, if they are just slightly scarred sand them gently with high grit paper, no less than 400. He almost always reuses them. He said they usually fail to seal because someone fails to clean the grit from all the surfaces. Also, be careful taking off the plastic top it's dark down there and with poor eyesight it's difficult to see that a narrow screwdriver will release the plastic prong that fits down into the sensor. You don't want to break that plastic apart.

    My temperature gauge reads a little high on a cold start but then drops to about center after warming up a bit. Could doing this fix my problem?

      A shot at your question, there's a sensor on the back top driver side of the engine kind of at the very back corner behind the driver valve cover and intake area. It's a straight up small circular single wire sensor. This is the actual sensor that relates to the dash board gauge, the etc in this video is not in control of the same function but rather the running condition and computer communication. Hope this helps.
