Specialised work
The work people seek out specifically
Not every job on an old engine is an overhaul. Some damage calls for its own procedure — and a workshop that has mastered it. Four of these we do regularly, including as individual commissions for other garages.
Crack stitching
Cracks in cast iron — cold-stitched instead of welded
Cast iron can only be welded to a limited extent: the heat warps the block and creates new stresses. In crack stitching, holes are drilled along the crack and a row of overlapping locks is set — cold, with no heat input.
The joint seals, the block stays dimensionally true, and the repair withstands operation. On water and oil passages, cylinder heads and engine housings.
Re-sleeving
A new running surface for old cylinders
In re-sleeving, the worn or cracked cylinder bore is machined out and a new liner is fitted. The bore is then honed to size — to the clearance the pistons and engine need.
This preserves the original block, instead of having to search for a replacement engine whose condition nobody knows.
Camshaft replacement
Valve timing as intended
Worn lobes and bearing surfaces gradually alter the valve timing — the engine loses power and refinement long before it fails. We replace the camshaft, set up the valve train and adjust the timing to factory specification.
Where a shaft is no longer available, we examine remanufacture or reconditioning — talk to us.
One-off parts
Making what no longer exists
Bushes, spacers, covers, housing parts: when a part can no longer be found anywhere, we make it from a sample or to measurement. The basis is the old part — whatever its condition — or measurements taken on the engine.
