machine shop needed in sudbury ont

I would not go to Unapco on Lorne St.
I had my #'s matching 340 done there.
After I got the car all together and fired up the engine , I drove it for a while.
It wasn't to long after that the car was "missing"
Took it to a friend of mine and he detected an intake leak AND a frost plug leak.
Unapco paid for the repairs but I wasn't happy.
How can you say that you re-built an engine and NOT change 90 cent frost plugs.What did they exactly do????
