It seems that in every 22R(E) full rebuild gasket set I end up with these as left overs. What are they for?

 

Could very well be something for engines outside the USA

These gaskets might be used on another engine only ours does not need them

 

Based on shape, I would say plenum gaskets for a different style intake. Not sure what other application they would come from.

 

I was thinking a different intake plenum or under the valve cover.

 

^^^ yep ... they are for the PCV cover on the underside of a 22R# series valve cover

Any idea how to get the PCV cover off?

 

it's bolted on .. just undo the bolts

wow that's cool. However all three of mine are riveted.

 

ahh , then if your insisting on doing it ..
like the 5vzfe VC's I powder coat , you'll need to "grind" the rivets off .. I use a die grinder , and trim the mushroom part of the rivet , leaving the post .
I then use a silicone gasket material to "glue" them back on when I'm all done with what I'm doing ..


.

 

this is what all mine look like

 

so why do you want to take the plate off ? you really don't ever have to remove this , unless your sandblasting the cover or something like that ..

If a person could replace the gasket easily then why not? But, evidently that is not the case for my covers. Wonder why Toyota made covers with removable PVC baffles and some without. Maybe it was a production and cost thing, who knows. At least now I know what the extra gaskets are for. ;-)
Thanks all.
