Lotus Marques valve guides are CNC machined from high quality Manganese Bronze material.
These are available in standard size diameter and +0.005 inch oversize.
These valve guides have been designed to be used in combination of our low friction nitrided and polished valves.
This valve and guide combination provides an ideal solution for both street and race engine applications.
Building any Lotus twin cam engine with these high quality components offers both performance and longevity.
Installation is simplified as the guides have an integral location step so no circlip is required.
Vehicle application details - to suit Ford Lotus twin cam 1558cc, 8 valve
Inlet valve guide weight = 26 grams
Exhaust valve guide weight = 25 grams
Combined engine set (8 valve guides) weight = 204 grams
Recommended guide to valve stem clearance –
Inlet = 0.0003 inch to 0.0023 inch (0.007 mm to 0.058 mm)
Exhaust = 0.0025 inch to 0.003 inch (0.063 mm to 0.076 mm)
When machining the guides to final size, it is recommended this be carried out with the aid of a diamond hone in order to obtain a mirror finish.
Setting the correct clearances is a critical operation as this will determine oil consumption and the next cylinder head service interval.
