Mustang orders held up.

Hi Guys. I have a Mustang GT on order. My car was supposed to be in around the first week of July. I spoke to my salesperson today and he told me the orders are slow. It has been 7 weeks and they havent started building my car yet.
I live in Windsor, Ontario. The plant where they are building the 5.0 engines is about a mile from my house. My salesperson spoke to someone he knows who works at the plant. He was told that they have had a few problems. One was some kind of "spring" that had to be modified or replaced. The other was a problem with engine damage . They are going to use a break in additive from GM. Yes a GM break in additive. My salesman is not very mechanical but the way he described the problem, it sounds like the engines are put together really tight with very little piston to wall clearance. People have been getting their cars and beating on them before proper break in and they have been experiencing some call backs. They think the break in additive will work.
So, I told the salesman that when they take my car to get gas, DO NOT PUSH THe ENGINE. When I get the car, I will put some miles on it BEFORE any WOT attempts. I have built my share of engines, and planned to break it in easy even before receiving this inside info.

Just thought I would share what I heard , Randy
