Late to this thread, but the shop needs to replace the pressure valve holder seals, they are leaking.
Knock at idle, rough idle, low power until about 2000 rpm, no smoke. Make sure they understand the correct method to torque NEW seals -- never allow them to re-use the old ones, they will never seal properly twice.
