The Dog House in Newport Beach California during the pre-purchase inspection checks.
Viking 56' awaiting diagnoses after the captain reported coolant loss and steam present from the exhaust on the port engine.
Before starting any works in the engine room, a plastic wrap is laid to protect the raw teak timber deck and points of access.
Laying a secondary more absorbent layer over the plastic wrap on the teak deck before loading tools onboard is always standard practice at Onboard Engineering.
Engine rooms are commonly used as a storage area, carefully removing these items to create clear and safe work space is a must before commencing any works.
Accessing the entire engine can be difficult when other vessel systems are placed in this confined space.
Injectors removed, ready to boroscope engine cylinders.
Inspecting a cylinder with the boroscope shows a clear view of a section of a valve seat.
On further inspection with the boroscope a coolant trail can be clearly seen on the cylinder liner.
Exhaust manifolds removed.
Cylinder heads removed exposing the pistons.
Conrod big end cap removed to enable removal of the piston.
Removing cylinder liners from the cylinder block.
Cylinder liners and pistons lined up ready for inspection.
Visually inspecting one of three thermostats.
Valve components laid out for inspection after removal from cylinder head.
Cylinder heads lined up after crack testing.
New MAN genuine pistons and liners lined up with conrods ready for assembly.
After the cylinder block has been cleaned, liner heights are checked and recorded with the new cylinder liners.
Checking big end bearing clearance with new bearings.
12 new cylinder liners and pistons installed.
Cylinder heads individually painted ready for reassembly.
New cylinder heads installed and torque turned down.
Last inspection of the lubrication pump, the heart of the engine before installation of the sump.
With the exhaust manifolds installed, the space around the engine a little tighter.
With the last of 4 turbo chargers installed, start up is not too far away.
Engine ready for start up after in-chassis rebuild.
Preparing both engines ready for full power sea trials before signing off on engine repair.
Both engines evenly matched after successful engine repair.
Exiting the engine room for the last time, ensuring it's in better condition than on the day of arrival.
The Dog House back out catching fish. One happy Captain Jon and the crew.
