I have chosen to use the PermaTorque head gaskets 9392PT. The oil passage in the gasket normally uses a rubber o-ring to seal it. However, there is a metal ring, looks exactly like a miniature fire ring, right there. Is that designed to eliminate the need for that o-ring? Thanks. cnc

Hi Cnc.

 

Just found your thread searching for the same answer. I just picked up felpros based on everyones recc's on here.

 

It appears they have a built in crush washer like you noticed.

 

I am sure someone will chime in if this isn't so. .

 

"bump"

Correct. It is an improved design.

Hawt dayum! What a relief! I really didn't want to yank the whole shebang apart. Again. This was the third time I've done the engine. I swore that next time, I'd just use velcro and zip ties to hold it in, to make it faster to pop out again.http://www.ultimatesubaru.org/forum/images/smilies/perplexed.gif
