To rebore an engine, replace it with a new one, pull out of the car and take apart to diagnose, ideally placing it on an engine stand, according to the car manufacturers instruction regarding the stand. When the Engine is ready to be mounted on stand, the
Flywheel/expiate should be removed and the internal oil and coolant purged, drained. This way, when you are taking out parts and fasteners during the demodelling process, then perhaps drawing pictures or labelling containers to indicate where things go, you'll find that there are many brackets and clips in modern engines that seem to look rather alike. First of, remove any of the accessories that may still be bolted on for instance the
Water Pump, power steering pump, and the alternator before you proceed to remove the remaining manifolds. Last but not least, the
Rocker Arm, front or timing cover, and
Oil Pan should be removed; the specification should be mentioned that some front covers will not allow the vibration damper or crank pulley to be removed before they are taken off. The aim is to merely have the bare components such as
Cylinder Head(s) or heads, valve gear, engine cast, crankshaft, piston and connecting rod apart from the in-block items such as the
Oil Pump and balance shaft. Last but not the least, ensure you take off the cylinder head(s) from the
Engine Block with a lot of care before putting them on a bench for further dismantling.
