Good advice above.
That is not too bad. All of mine were tight except a couple when I picked up my car. The PO stated that "it ran so good, I never had them adjusted".
Check the exhaust manifold carefully for cracks while you have it off and be sure to get all the crud out of the intake before you put it back on. Be sure to use a new gasket (do not re-use the old one). Good time to do an EGR block kit.
As stated above... This is a great time to replace the oil drain seal for the turbo. That is a common and messy leak. Clean up that side of the block and check the starter connections. I would also check that the Aux. pump is working too (while you have everything out of there). Then pull the battery tray and clean up underneath and fix any rust.
