Ivor Searle adds Vauxhall A20DTH engine - 10.03.2017

Ensuring that it continues to provide its fleet and factor customers with the widest range of remanufactured engines, Ivor Searle has added another manufacturer unit to its stock list with the Vauxhall/Opel A20DTH diesel engine.

The UK’s leading engine remanufacturer, Ivor Searle, has further expanded its unrivalled range of remanufactured engines with the addition of the Vauxhall A20DTH 2.0CDTI unit.
Introduced in 2013 and manufactured by GM until 2015, this diesel variant develops 163 PS (160bhp) and features stop/start technology as part of Vauxhall/Opel’s ‘eco flex’ range of engines.

For customer peace of mind, Ivor Searle guarantees a one year unlimited mileage parts and labour warranty on all engines with overnight national delivery on stocked items, if ordered before 3.30pm.
Every engine remanufactured by Ivor Searle is built following the BSI code of practice BS AU 257:2002, which provides a clear distinction between engines that are professionally remanufactured and those that are inferior, reconditioned product.
Our rigorous process includes the following:

  • Camshafts are either replaced with a new unit or reprofiled to their original valve timing and lift specifications
Cylinder Head
  • Every cylinder head is inspected for cracks
  • Engines with OHC configurations have the camshaft bores measured for size, ovality, taper and alignment and are either restored to OEM specification or scrapped
  • Valve guides are measured for wear and either resized or renewed to conform to original tolerances
  • Valve seats are machined to retain the correct seat angles, widths, valve heights and valve seating concentric with the centre line of the valve guide bore
  • Valves are examined for damage, head thickness and stem wear and replaced or machined as necessary
  • All valve springs are tested for squareness, free height and compressed load length
  • Cylinder heads are checked for distortion and thickness
  • When machining the cylinder head face, attention is paid to maintaining the surface finish specified by the gasket manufacturer.
  • After grinding, all crankshafts are polished to produce the exact dimensions and surface finish required.
  • Diesel crankshafts are electro-magnetically crack tested
  • Seal diameters and nose ends are also measured and, if necessary, reclaimed.
  • Blended radii, thrust wear and alignment are also checked
  • Oil galleries are de-burred and thoroughly cleaned
Cylinder Block
  • When refacing the cylinder block, attention is paid to the surface finish and deck height
  • Each cylinder block is rebored or resleeved and honed to give the precise surface finish and cross-hatch required
  • All main housings are measured for size, ovality, taper and alignment and machined as required
  • Big end housings are measured for size and ovality and are re-sized as necessary
  • Small end bushes are measured and replaced if found to be outside OEM specification
  • All con-rods are checked for alignment and are weight graded into engine sets
Oil Pump
  • The clearance between the pump’s body and rotor are measured
  • The oil pressure relief valve is dismantled and cleaned and all non-conforming parts are replaced
New Components
  • All remanufactured engines are equipped with new pistons, piston pins, piston rings, mains and con-rod bearings, timing chain or belt gaskets, oil seals, core plugs and oil filter
  • These new components are carefully selected for their durability and reliability and are sourced from the same producers that supply the vehicle manufacturers
  • All diesel pumps and injectors are remanufactured to perform to OEM specifications by a diesel injection specialist
  • Every engine is tested in a purpose-built test cell and subjected to a series of checks, the results of which are recorded against each engine’s specific serial number.
