These small seals (about 1/2 inch in diameter) came in the same package as the cam seals with my engine gasket kit from Toyota. What the heck are they and where do they go? I assume they are some kind of oil seal but I didn't run across them yet in my teardown (or my buildup for that matter :) ) TIA

Defenetly not injector seals, those are like rubber O rings. What you have above is a shaft seal, look too small to be cam seals. I have no idea what they would be for, I just rebuilt my engine and never seen a seal smaller then the cam seals on the engine.

Can't really see in the picture but if there is 8 Black and 8 Brown they are your valve seals. They attach on the top of the the guide.

are they the gaskets in for the spark plug holes where the valve cover mates with the head?

Edit: Oh, i just saw the " 1/2" in diameter ", spark plug seals are prolly like 1"-1.5" diameter.

This is a 3sgte? OEM toyota kit? I am kind of curious now. I have the EPC if you had part numbers for them I could look it up.

It's a factory gasket kit (dealer) supposedly for 3sgte (Toyota part #04111-74240) but I'm beginning to think that I have the wrong gasket kit because also the gasket for the turbo oil pipe only had 3 holes instead of 4? (TC 4 and TC8 in BGB). That would have blocked the oil feed line?

Mine came with them too. I didnt use them when i did a complete rebuild. I assumed they were for the oil/water pump.

Yea, I think they are for rebuilding the water or oil pump. I replaced both pumps with brand new, so i never opened up the old oil or water pump.

Ahh i think you guys are right, I was wondering why I didn't get those with my kit but then I rememberd I only got the gasket kit for the top end not the whole engine. The Oil pump seal does look like that, that pully unbolts. I replaced my pumps too. Have no idea how the water pump pully comes off.

they sorta look like water and oil pump front seals.

-I agree with Mike here, when I replaced my timing belt, I also replaced the crank seal, oil pump shaft seal, cam seals, and others.
-I'd say one is for the oil pump shaft.
-I thought there was another similar shaft down there on the passenger side of the engine too, but I'm at work now and just can't recall what it was (?).

HINT : Take a look at your TVIS spacer with the shaft mounted butterflies.

HTH, Andy
Andy, I'm looking at it, but not seeing a place for these two seals. Can you explain it further?
EDIT: took an even closer closer look and I think I see them. Should these be replaced? Exactly what do the do? (what are the symptoms if you don't?).
