squeal at 2200 rpm

Wish it was the pig, I could at least get some bacon out of this. Actually the verdict is in. Seems it's the exhaust manifold gasket. Been in the shop for 6 days now and should be back by weeks end. They had to drill out the bolts, or some at least. They reported the manifold is straight so no milling. I told my wife I almost wish it was the turbo so I could at least have a new part for my money. Oh well, this is the first repair this engine has ever needed, certainly not complaining about it.
Thanks for all the replies, you all made it easy for me to ask the right questions to the repair shop.
