In this guide we’re turning our attention to the removal, cleaning, and refitting of the oil strainer gauze on a Silver Spur III. Fewer than 500 Silver Spur IIIs were made in total, of which only 176 were right-hand drive, making this all-white example something of a rarity. In good condition inside and out, it makes for a nice rolling restoration project for someone.
A clogged strainer is a very common issue – a tiny part that, if not properly maintained, can cause all kinds of problems. If the strainer gauze gets blocked, it will basically starve the engine of oil. This can clearly have serious implications, not least premature wear, especially at the top end of the engine, the camshaft, and rocker shaft.
The strainer gauze generally needs a good clean every 25,000 miles or so, and, while it isn’t the easiest job in the world, it is within the scope of more accomplished DIY repairers. The main benefit is faster lubrication to all internal components, preserving the longevity of multiple vital (and expensive) parts.
Please remember that old engine oil is hazardous waste. Most local recycling centres accept it. As always, the usual caveats apply. Please note that these articles are intended as general guidance only; for model-specific instructions, refer to your owner’s manual.
Finally, and I can’t emphasise this enough: safety is paramount. Please use the appropriate personal protective equipment (PPE) and dispose of waste products responsibly.
Boy, that means this car has had infrequent oil change services to be this bad after relatively few years.
Much more applicable to Shadows and Clouds. Even worse is when the oil pan is bent upwards a bit from curb running. The RR V8 oil pick-up screen is rigid unlike other cars with a hinged oil screen. There is only about 1/4 inch gap between oil pan bottom and rim of screen. I have scraped sludge away from rim with rigid wire loop through oil drain hole on several cars. Then flush oil pan with spray of solvent through drain hole.
