Master Ford Tech
Well i checked on my truck yesterday. they were installing the heads. They had to shave both heads for flatness, replaced #8 injector, changed nozzels, orings, and copper washers on the other 7, and they are going to replace the egr cooler. I decided to leave the cooler stock untill I upgrade the turbo.
I will have my truck back by Tuesday. I got all of my info from the tech and not the service writer. Well maybe with the studs in i won't have to worry about this again.
Ford doesn't recomend machining of the heads, there supposed to be replaced. Heres the inspection procedure out of the book.
NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket and other foreign material.
Following the directions on the packaging, use silicone gasket remover and metal surface prep to clean the cylinder head of all gasket foreign material, RTV, oil and coolant.
NOTE: Use a straight edge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of length, such as Snap-On® GA438A or equivalent. For example, if the straight edge is 61 cm (24 in) long, the machined edge must be flat within 0.010 mm (0.0004 in) from end to end.
NOTE: Measure locations 2 and 3 first. These 2 locations are most susceptible to wear or damage.
Measure cylinder head flatness to make sure that there are no depressions of 0.0508 mm (0.002 in) or greater in the cylinder head.
Place a 0.0508 mm (0.002 in) feeler gauge on one of the measuring points.
Place the straight edge on top of the feeler gauge with the straight edge transverse to the cylinder head, as shown.
Gently pull on the feeler gauge.
If the feeler gauge is loose or slides out from under the straight edge, install a new cylinder head.
Depending on how much they took off there could be valve to piston clearence issues. I would question why they didn't replace the heads.
