Plugs, valve seats and cylinder head parts

Welch plugs are a major part of the range, including brass plugs listed in imperial and metric sizes. Valve seat inserts are listed by outside diameter, inner diameter and depth, alongside other valvetrain and cylinder head items such as lifter repair kits. Measure the bore or seat pocket and compare it with the listed dimensions.

Dowels, repair inserts and engine components

Many items are engine-specific, including location dowels, head bolt and water tube repair sleeves, bushes and gallery plugs. Others cover oil pump gears, shafts and relief valves, oil pump springs and head gaskets. Check the engine named in the title before ordering.

Fasteners, fluids and sealing extras

Manifold studs and nuts are listed by thread size and length. Sump plugs, including standard and magnetic versions, and sump plug bushes are also listed. Cooling-system flush and sealers and bronze lube sit alongside them. Confirm thread and size details on each listing.

Workshop and machining tools

Tooling includes reamers, reamer bushes and collars, ball broaches, auto drivers, sleeve drivers, removal tools, go/no-go gauges, taps, stitching pins and sump plug tools. These are sized to match specific bores, guides or applications, so check the size shown for your work.
