I know what you mean.Darn drain plugs are a definite pain on those.On another note I ran into problems on a 08 5.4 triton last week when installing a new manifold so I noticed a broken manifold stud in the rear lower section of the driver side cylinder head and well recessed into the head.There was no getting it out.At the start of this summer I decided to change out my antifreeze, decided to go with John Deere's "Cool Gard II" - since it was so expensive I was sure it had to be concentrate.
Fast forward to today.
Flushed the system 5 times with distilled water and when I opened the John Deere liquid I saw it was indeed not concentrate.
So I tried to locate my drain plugs on the block - they were both behind the motor mounts. Unbolted the starter and knocked a freeze plug out. Spent the whole evening trying to knock a new (steel) freeze plug in the block.
1/10 not a good experience.
A drill bit was cracked off in the middle and I tried multiple times welding on it to build it up with flat washers being welded on that and a nut on top after that so I ended up drilling a new hole just above the broken stud area and made a 5/16 stud and drilled/tapped for that and redrilled the manifold to accept the new stud location.It was a risky repair as the new stud location is within a water jacket but there are no leaks after putting permatex steel weld epoxy to the stud threads before entering the cylinder head.
