Hey Dudes,
My buddy Sean and I have another video for you. If you have a leaking valve cover gasket on your 1FZ-FE engine, this video will show you how to replace it along with other associated parts like the spark plug tube seals, PCV valve and grommet, a couple vent hoses, throttle body gasket and either resealing the 2 half moons on the head or replacing them.
The one thing we want to hit home with this job is the Toyota FSM specifies a 15 ft-lb torque value for the 13 valve cover bolts and we believe this is too high. We did do a test to figure out how much force was required to remove one of the bolts and that value was 170 in-lbs. So, it sort of appeared the 15 ft-lb spec was accurate. But, when we got to around 160 in-lbs or 13 ft-lbs, I started to cringe that going any further would have potentially broken one of the bolts in the head. Doing some research on this subject, I found a couple threads on this forum with people having the same concern that the FSM spec of 15 ft-lbs is too high. After getting the bolts to 160 in-lbs, I did do one final pass with a standard length 3/8" ratchet and was able to turn some of the bolts a tiny bit more without feeling like I was using too much force based off the size of the bolts. So, please use your own judgement when tightening down these valve cover bolts. The main thing you want to do is make sure you tighten them down evenly in a crossing pattern and gradually bring them up to the spec you feel comfortable with.
Here's the video and Enjoy the Show!
