Just left the shop and still no definitive answer. The torque on the intake was correct so that wasn't the issue. His suggestion was to put a few hundred more miles in it and watch
oil level and exhaust. With the low miles, previously owner only put 875 miles in 4 years, he's wondering if everything has had time to properly seat. Don't know if I'm excited it was nothing major or nervous since we still don't have an answer. I'll keep you posted after we put some miles on the car.
