Where are those eight spots on valve cover of 3s-FE engine?

[jay_wang2000]

Previously, I had posted one " Remove 3s-fe valve cover ". Someone said "Dont forget to use high temp sealant on those eight spots." when installing valve cover gasket. Can anybody tell me where those eight spots are ? Thanks in advance !

In the 5FSE same locations,

next to the cam journals, on both sides of block.

Get O2 Sensor safe sealant.

You don't need sealant for the valve cover, thats what the valve cover gasket is for.

The sealant on the 8 spots is for the camshaft bearing caps (the 2 end ones on the intake cam) and plugs (Toyota calls em semi-circles) on top of the head.

Thanks ! Hence, It is not necessary to put sealant.

It depends on the individual car. Some will leak, some wont.

Can anybody illustrate the location of those 8 spots by picture or sketch ? Thanks in advance !

Here... (sorry about quality, only way I could get it attached)

Thanks for your diagram. As for sealant, can I use the "ultra copper" of Permatex as sealant ?

[Meisner]

NO! Use oxygen sensor safe RTV!

I have another question. The sealant on 8 spots should be put between valve cover gasket and engine body or the gasket and valve cover or both.
