Block dissassembly:

All blocks are visually inspected for casting defects prior to their disassembly
 and the beginning of engine block remanufacturing.
The parts are then removed and individually inspected for damage and cause of failure.
The oil and water passage plugs are removed to insure optimum results during the thermal cleaning process.



Only premium castings are used for our marine blocks, all castings are replaced in all salt-water applications.
 Our high performance engines are built with premium cores. In many applications new castings are used, as we never employ repaired castings or sleeved blocks. To retain your classic car's original block casting, Promar employs the artistry of our skilled casting repair technicians.
