Semi-finished liners once fitted to the cylinder block, require boring and honing to size. Finished liners are supplied pre-bored and once fitted may only require a light hone. Liners basically come in two different flavours: parallel and flanged. A description of these are below:

Parallel liner: as it says, the parallel liner is flat on all edges.

These are held in the block by an ‘interference’ or ‘press fit’. Meaning the liner is marginally bigger than the parent bore of the motor. When these are pressed into place, they may distort and conform to the shape of the parent bore. Available only in semi-finished (needs to be bored to size).

Flanged liner: yet again, as the name implies, these liners have a flange at the top.

This flange locates into a counterbore cut into the top of the parent bore. These liners can be either ‘press’ or ‘slip’ fit. Available in either; finished (pre-sized) or semi-finished (needs to be bored to size).

Black smoke: it indicates poor and incomplete combustion of the diesel fuel.

Block air filter or intake system
Problem with fuel injector pump or injectors
Engine timing out
Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Restricted induction system
Excessive carbon build up in combustion and exhaust spaces
Incorrect valve clearance

Blue smoke: is an indication of oil being burnt.

Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Worn oil rings – sticky oil rings when cold
Worn valve guides or seals
Cylinder glazed
Incorrect grade of oil (e.g. oil too thin, and migrating past the rings)
Fuel dilution in the oil (oil thinned out with diesel)
High engine oil level

White smoke: occurs when raw diesel comes through the exhaust completely intact and unburned.

Faulty glow plugs
Low engine cranking speed
Problem with fuel injector pump or injectors
Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway)
Fuel air leak
Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Incorrect valve clearance
