When NWS Motor Services recondition and engine, it will be completely stripped down and inspected to see what parts are within tolerance.
After inspection everything is put into a hot acid tank, not just to remove the dirt and grime but also so all oil and waterways are clean and free from debris.
This is especially important if the engine components have been badly damaged due to something like an oil pump failure.
After cleaning, all the separate components are taken to respective stations where they are reconditioned.
The block is rebored/honed and the crankshaft reground/polished, with new piston rings and new bearings being ordered to suit.
The cylinder head is pressure tested, skimmed with valves faced and valve seats re-cut, any valves which are bent or showing signs of extreme heat are replaced.
Valve guides are also inspected for wear and replaced where necessary.
After all gasket surfaces and components are spotlessly clean it is then all re-assembled using new gaskets, oil seals and an uprated oil pump.
If you have any questions regarding the reconditioning process then please phone, we are always happy to help.
