I had a shop install a Streetmeg on my 2008 ZX14 and it started to leak lots of motor oil from the top of engine. What do you think went wrong with the install? Is it coming from the air box or valve cover gasket? Did they plug up the wrong port or hole.?

I own an '07 ZX14 with PCIIIUSB, Roaring Toyz low-exit megaphone exhaust, Pipercross air filter & a custom map by a local custom tuner.

Any comments or advice would greatly be appreciated.
