Changing valve cover gaskets on stock 2JZGE
So I'm going to change the plugs on my 1992 SC300, I've read the thread about it, seems like a fairly straightforward job once you get the throttle body and "Y" part of the intake out of the way. Seems to me the easiest thing to do is to leave the "Y" and throttle body attached to each other and just unbolt the "Y" part.
Anyways, the valve covers are seeping a bit of oil now, so I figured I'd change them while I had everything apart. Is it a real PITA to get the valve covers off, do I need to remove anything else to get them off?
Also, what do you recommend I use on the new gaskets? Everybody seems like they have their own preferred method and different type of goop they use on gaskets, input here would also be appreciated.
Also what is the torque spec for the valve cover gaskets? Or is it just kind of "hand tight" with a small ratchet sort of deal? I know the spark plug spec is 13 ft lbs if I remember correctly from the other thread.

It has been a while since I messed with a stock 2JZGE motor. You should be able to remove the Y pipe form the intake to access the plugs. I remember there are a bunch of vacuum lines at the bottom but once the Y pipe is off you should be able to access the valve cover easily.

Its a pretty simple task to do once you remove the y pipe. When you take it off also inspect the hose because sometime they maybe old and crack. as far as gaskets cant go wrong with oem. Since you will have the y pipe off i would inspect plugs and change them out since you will have the y pipe off. Would be a pita to do the gasket and then a few weeks later you change plugs. As far as how much torque, i usually just hand tighten them. just be careful not to tighten to much or you may crack the part where your are tightening( i made that mistake before).

Okay, this doesn't seem that hard since once you get the y and throttle body off, you have really easy access. Oh and I was planning to do the plugs and valve cover gaskets at the same time.
Anyways, what do you recommend I use on the valve cover gaskets for a sealent??? I have some red goop that is in a can that I used for a water pump gasket, looks like this stuff, but not that brand. Lid unscrews and it has a brush where you put the stuff on there.

It's a bit of a job but it's worth getting all the video tutorials and the TSRM to do it yourself. Take your time and do everything step by step and apply the FIPG gasket maker carefully. It's a good thing to do once these engines accrue over 200K miles. Very tedious but once it's done, it's done.
Also, since you'll have the valve covers off to do it, if you do have the safe garage space and downtime to allow, it's a great time to take your valve covers to a local specialist who will media blast and refinish your OEM valve covers.

Dude,
The valve cover gaskets is all that's needed. No sealant of any kind. As for removing the throttle body with the "y", it's best to remove the throttle body first. You'll then be able to see and mark the random vacuum hoses before removing the "y". It's the vacuum hoses that makes this a somewhat annoying job.
-good luck

I don't see the point in painting them since they're covered up by some plastic beauty trim.

Aron, it's subjective of course but the original finish usually doesn't look so great after 20+ years. I did not allow the downtime to have mine blasted and painted (or powder coated) when I did my valve cover gaskets and I wish I had. By plastic beauty trim do you mean the front cam cover and rear plug cover?
