    Heads-up for '05 IC installers

    I came across this today while installing my IC. NO O-rings! Instead, 1" wide, flat "bands". If you are doing this install on an '05 you might want to ensure you have a 3" O-ring on hand in case you run into this.

    I'll try and find one at a implement store tomorrow... don't want to miss the weekend

    I got my blockoff today and it didn't come with the green o-ring I heard about. I tried both of those wide bands things and still couldn't get the block-off in.

    What do I do ?

    I thought about putting rtv gasket silicone on it and just putting the clamp back on. It's a little loose if you put it in there without a rubber ring.

    I tried the clamp method to get it on and that didnt work.

    Kinchyle, take a razor blade and cut the black rubber band down to the thickness of the O ring groove in the blockoff. Install it in the groove and then use black RTV and you will be fine.

    Nope!... I looked everywhere... no luck.

    I ended up doing exactly as Jerry suggested... cut the flat gasket narrow enough to fit in the groove and add a bead of silicone to the "fillet" of the block-off plate... worked great.

    I have since heard that the new block-offs have beened milled differently, but don't know that for sure

    I got one at a pool supply store. I had to cut it down a little but it worked.

    I ended up cutting it down and putting rtv gasket silicone under the ring and on top of the ring. Then unloaded half a container of the silicone around and at the top of the blockoff then used the clamp method to get it all the way in.

    I hope that holds because removing something with gasket silicone is a b*tch.

    I'm going to start gearing up for a boost gauge to see if I'm loosing anything.

    I saw this,

    I wonder if it would help find pressure leaks...

    guys you can make your own gaskets. I've done it for work with high vacuum systems that require perfect seals. Find an oring that is the corect thickness, but much bigger (diameter) then what you need. Cut it down to size and superglue the two ends together to make a new gasket.

    There are also special kits out there that hold the gasket perfectly while the supplied glue sets up. I think harbor freight sells a cheap kit.
