If you are supposed to put sealant on the cork timing cover gasket why doesn't the factory manual say to do it? last time I used Gasgacinch to tack it to the timing cover and FIPG on the side that faces the block and it failed, has anyone not used sealant? When I replaced the side cover gasket I didn't use it and it hasn't leaked yet.
No sealant. You might want to moisten it with some fresh motor oil. Be vigilant with the torque specs. It's in inch-pounds and it's less torque than you would do without the specs.
Eddy, just putting a little oil on my finger and spreading it on the block side of the cork will be ok?
Glad I read this post, I am hoping to replace my gasket in the morning and was planning to use sealant on the gasket.
I like it how the FSM says "When necessary, use a sealer on gaskets to prevent leaks" Great specific instructions.
recent thread:

If you are replacing the gasket b/w the timing cover plate and block and the screws currently fastening it are flat heads then do yourself a favor and replace with the torx head style. You can still get them from your toyota dealer...I don't have the part number handy but can get it from a bag I have at home.

Before you do anything to the timing cover seals, make sure your cover's mounting surface is FLAT. If not, it will increase your chances of a leak returning. Flatten out any warped sections as good as possible.

Also, be sure that you install the harmonic balancer onto the crank BEFORE tightening down your timing cover bolts as the balancer centers the cover on the seal.

ALSO...there are certain bolts on the timing cover that are through holes to the oil pan cavity...and these will need thread sealant to prevent leaks.

I took all the above precautions when I replaced my timing cover and the bastard still leaks like 1 drop of oil after every drive...way less then before but unfortunately not leak free.

I usually save this story for the campfire, but my buddy bested me by heating his pulley in a small electric toaster oven while he cut the top off of a coke can and poked a small hole in the bottom. Slipped the can over the end of the crank and juiced the crank with a blast of CO2. The crank pulley SLIPPED ON LIKE MELTED BUTTER!!!!!!!!!!
My Harmonic balancer (i'm assuming aka crank pulley) came off and went on like it was greased. But I read these type of tips and people using pullers to get this off. Hopefully I have the perfect fit and y'all's is off ;)

Either that or i'll get a slight vibration that will cause every bolt in my engine to fall out.

Now for the crank shaft pulley nut. Loosening this thing with the starter worked great but put my final solution off until now. OEM SST? Autozone tool rental? 2x4 with holes drilled for the bolts? belt?

I'm going old school and didn't put sealer on the cork gasket. Hopefully my skills at flattening the cover flange work and the oil will infiltrate the cork and create the best seal, as Toyota intended. Put the intended B sized screws where they belonged as well, available only in Torqs. Although the top one comes pretty close to hitting the block.
