Description
ENGINE BLOCK REMANUFACTURING
TIG Welding Aluminum Heads
After welding, the head must be allowed to slowly cool. A long,
slow cool down relieves stress in the metal, which if not relieved
could lead to cracking.
After the head has reached room temperature, it should be pressure
tested to check for leaks. Coating the inside of the water jackets
with sealer, or adding sealer to the engine’s cooling system after
the engine has been installed can provide additional insurance
against future leaks.
ENGINE BLOCK DISASSEMBLY
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.

ENGINE BLOCK THERMAL CLEANING
The thermal cleaning system gives our customers the closest thing
to a new casting, taking engine parts to a whole new level of
clean. The heaters emit uniformly controlled heat, which is evenly
distributed throughout the chamber. This method totally eliminates
the concentration of intense heat or flame entering the chamber,
which could overheat, warp or melt parts. The load is heated to
650-800 F (340-427C) in an oxygen deficient atmosphere, where the
combustible hydrocarbons decompose and parts leave the oven
completely dry. This baking process used on cast iron blocks only
employs the Ace RKE 230 oven. Ash residue is easily removed by
stainless steel shot blasting which is the next step of our engine
restoration services.
