Pre-start checks for barn finds

The only way to know how good or bad an old "barn-find" TS3 engine is, is to pull the engine down and start measuring and inspecting.

These days, because original spares have thinned out, I have are now used for the engines I recondition and where Churchill Special Service Tools are required to recondition a TS3, starting an old TS3 up after years of inactivity is never a good idea.

In most cases I recommend you don't even turned over before stripping, checking, cleaning etc, which also includes fuel injection equipment and blower.

If you disregard these recommendations, you can easily damage an engine that would otherwise be in good condition.

Here is a check list of things to do before attempting to start:

 - Remove the sump to check for sludge build up. Clean out where found.
 - Install new oil and filter (Shell Rimula R3 Plus SAE30 monograde)
 - Remove the injector pump and invert to remove old fuel, foreign matter etc.
 - Check inside the pump housing for corrosion. If any is found, do not use and have serviced before attempting to start engine.
 - Replace the fuel filter.
 - Remove injectors and have tested at a fuel shop to make sure needles aren't stuck, damaged or worn out. Have serviced if they are.
 - Bleed  the air from the FIE.
 - Remove the outlet manifold from the blower to check for debris damage, corrosion etc.
 - Make sure the rotors are turning freely and not stuck. If stuck, remove blower and have serviced.
 - Remove the exhaust manifold to check that the exhaust ports are clear and not blocked with carbon deposits. If so, de-coke the exhaust ports exactly as described in     the workshop manual. 
 - Remove the thermostat housing to check the thermostat is not stuck open. You could start the engine if the thermostat is stuck open, but will need to replace the             thermostat later because as with all diesel engines, operating temperature is extremely important.
 - Do not start the engine without water in the block. Rig up a closed circuit between water pump and thermostat housing and fill with water, bleeding air out of the top of     the block from the water temperature sender opening.
 - Any work being done as described above, make sure it's done by a competant diesel mechanic, strictly following the workshop manual instructions.
