I'm getting ready to do replace my valve cover gasket (94 FZJ 80) and I cant find much on this job in my electronic copy of the FSM. It seems like a simple job- remove TB, remove plugs and wires, remove valve cover, replace gasket and reinstall. Does anyone have a copy of the FSM procedure for this or any other suggestions or tips?
 
It's simple, pretty well as you stated above.

I'd suggest replacing the spark plug seals may be a good idea while you 'are in there' if they are original/old...

Thanks for the write up, thats very useful. I ordered new plug seals, will definitely be installing them.

Is it worth re FIPG-ing the half moons? I've heard these can leak.
 
I didn't bother - mine were in solid.

cheers,

I removed, stripped and resealed the moons when I did mine. Honda Bond or Three Bond replicates the OE rtv well in my opinion.
 
Don't break the nipple off top of radiator when you crawl in there to get to back bolts.
A flex adapter for 1/4" Socket will help with back bolts.
I did PCV Hose, Gasket and Valve while I was in there.

Yes do the half moons. Its such a simple job...there is no reason not to. They've been there umpteen years, even if not leaking...why would you not take 10 minutes to clean them and reinstall with FIPG.

That way you KNOW you aren't going to have a problem for many years to come. IF you don't and they do start leaking later, the you'll be pulling the valve cover again.

@Flintnappers logic is good, but if they aren't leaking leave them alone.
You stand a better chance of them leaking afterwards than if you never touched them.
Checking them is as easy as opening the hood, unlike the PHH or Antifreeze mixing valve.
 
I ended up using the Beck Arnley gasket set that came with the spark plug tube seals. I know I'm going to get lots of criticism for not using OEM and I agree that OEM is the best option here. I used the Beck Arnley gasket because it was on Amazon with free 2 day shipping and I had a trip coming up so I wanted to get the gasket replaced ASAP. I will say the Beck Arnley gasket seemed to be high quality and it had a made in Japan sticker on the package.

Also, I thought this job was shockingly easy, it look me less then two and a half hours even dicking around taking pictures and re-tensioning my new fan/alternator belts (the tensioning bolt on the alternator is in a really awkward spot). My old gasket was pretty bad (it felt like hard plastic) and most of the spark plug tube seals stayed on the tubes rather then the valve cover so it was definitely time to replace. I did a ton of PM a couple months ago so I already had a new heater valve, intake tube, PCV valve/rubber line, throttle body coolant lines, etc. (all OEM from Beno) so I didn't have to replace any of that.

Many thanks to all who posted up with tips and suggestions, it made this job much easier.

Also does anyone know why on partsgeek.com it says ishino stone is "OEM"
 
I used the beck Arnley set on mine a couple years ago. Still no leaks. I also used their tube seals. No issues. Great product and it was pretty inexpensive

Ishino may be the OEM Supplier for Valve Cover???

I know they are OEM supplier for the PCV valve grommet of which I would replace at same time else it fall in when removed and you have to remove valve cover again.
 
I think ishino is the OEM supplier from what i read I purchased the gasket kit, toyota belts! Now i just need to order spark plugs and wires! does anyone know how much better OEM wires are then NGK
 
For what it's worth, you can get a Toyota OEM valve cover gasket for $17.50 from overstockoemparts.com.
 
The dang seals are $10 a pop from the stealer though. Mucho expensivo.

Also, for cleaning, don't use brake cleaner; use TB cleaner and a lil elbow grease. Brake cleaner will swell the rubber thats in the cover.

How difficult is it to replace the plug seals? I've never done this but I'm replacing the valve cover gasket, plugs, wires, distributor cap, rotor, (did PCV a few weeks ago as it takes about 2 minutes...)
 
My plug seals all fell out or could be easily removed by hand. You can push the new ones in most of the way by hand, I seated them all the way by tapping with a rubber mallet, not difficult at all.
