Anyone ran one of these before? just bought one, expected it to be a 5 second swap, and it sort of sux... My OEM cap does not have an O-ring, this new one came with one. The O-ring causes the cap to pop off when the air expands from temperature, but without it the cap does not seat well like the OEM one.

 

Removing power steering all-together solves this problem...

 

Savaaaaage- I thought this cap would be a nice piece to aid my possible sale/temporary severance from racecar lifestyle (check the cars for sale section in a bit)

 

Ended up drilling a .025" pinhole at a 45 degree upwards angle out of sight and it's all good.
​​​​​​The cap wouldn't even sit flush when you went to push it on, let alone after it heated up, now I hear a big rush of air go through the pin hole as it seats properly.

Really questioning the momentum brand (out of biz) and moreso the place that I bought it from who said they had no issues issues with theirs...
