Are you sure 0.003 is the correct clearance for an aluminum block? Aluminum expands a bunch with temp. The aluminum Modular 4.6 calls for around 0.0015 if memory serves me.
A local builder told me that he has never seen a new block from any company that was ready to assemble. They all need to be checked and many things need corrected every time. So, don't feel bad. Be glad you had it checked.
Also clean it and clean it and scrubb it and clean it every way and every angle you can think of. Casting sand in a new block can kill your engine. After you are absolutely positive you have every oil gallory and water jacket completely clean, clean it three more times. |
