Cam seal or valve cover leaking?
#16
when i started taking off panels to get to the valvecover bolts it was obvious it leaking around the valve covers it was even leaking a lil on to the driver exhaust manifold. i hope tighten the bolts work.

Remember to add some RTV at any corners if you plan on replacing the gasket. I HIGHLY recommend Toyota's Form In Place Gasket (FIPG). It's the best damn thing ever. Liquid rubber might be the appropriate term. Slightly expensive, but I honestly can't go back to using some of the Permatex stuff anymore. My buddy who runs a mechanic shop uses it to make valve cover gaskets all the time and the failure rate is 0%.

GSteg@-I used Permatex Black Ultra, I am planning to change the timing belt at the next 50K so I hope it's good enough.
Guys, I took the big circular plug off (2" diameter) along with semi-circular camshaft (I don't know what it's called, it's holding between the head and valve cover with 2" diameter circular plug) from the rear of the head on driver's side. I put some ATV around the plug and put it back on. I strongly believe oil was leaking out of the plug.
By the way, I accidently stripped and broke off one of valve cover bolts. I hope it's okay with seven bolts if I tighten much more?

Python@-no, it was not sealed with RTV before. I believe 2" diameter plug is made of aluminum, it is covered with plastic or paint. From a human's eyes, it looks like black plastic but when I touched it. I could feel the weight. I didn't put ATV on the plug on the passenger's side because it didn't leak plus it's VERY VERY difficult to remove and put it back on!!! I wish there is a door for us to enter to repair on the back of the engine from the floor panel area. Maybe I should make one? HA

No, and I wouldn't even dream of leaving a bolt out. Maybe on an interior plastic panel but not on something as important as a valve cover. Common sense will tell you if there's a bolt there it needs to be there and tightened to the correct torque.

Ha, let me know after 10 miles. Is the bolt one that you can see? I mean, an easy out will only take 15 minutes to get it out if you can see it and then ya don't have to keep checking it to see if it's leaking.
