Gasket above the plugs....

GreenChevelleSS · 10-12-2005, 04:24 AM

My gasket that is above the spark plugs is cracked and coming apart. What is this and where can I get another one? Its where the top of the plug wires seal to the head.... whatever....

yes, as far as i can tell it just holds the spark plug boot firmly inplace and has some stand offs inplace to support the plug wires. i seem to recall it being very hard to get the large allen "nuts" loose to remove and install the new gasket.

Mines off I just need a new one, any idea on where to get one?

In my service manual, it is called a cylinder head cover, but they also call the valve covers a cylinder head cover. It is just for keeping the alignment of the plug boot straight over the spark plug. The part could be sand blasted and then powder coated to look really nice, well what little you can see of it anyway. It seems that there is some sort of covering on that part and it peels off over time and with the heat. I have never seen one in a gasket set, but I have yet to find the 2 donut seals that go between the exhaust manifold and the double down pipe for my N/A. I get the big one that goes on the cat converter, I had always wondered what that one was for until I replaced my converter and saw the gasket there.

Oh well...........

It called the #3 valve cover gasket byt my toyota dealer. Cost $35. Dealer only part. 1 day order. It is there to keep debri and water from getting down around the spark plugs.

The 14mm allen head bolts come off easy enough. If you don't have the socket, you can make a tool with a 14mm head bolt and 2 nuts. Just put the 2 nuts onto the end of the bolt and 'lock' them together (double-nut), then put the 'head' into the allen bolt and use a box end wrench on the lower nut to unscrew the allen bolts.

Going back on, they just need to be tight, not really 'torqued', as they only hold the gasket in place.

Do they require any type of sealant on the threads?

mrnickleye · 10-13-2005, 04:28 AM

NO sealant needed.

id use a dab of anti-sieze when you put it back together. on all the threads for that matter. those allen nuts were really stuck in there.
