An oil analysis showing contaminatnts such as silica, crome or iron indicate signs of wear. The silica comes from dirt entering the engine through the air intake. Dirt is the number one cause of bearing wear so this problem must be corrected early. The chrome and iron particles are a result of the wear caused by the silica. To correct this problem a full inspection of the air intake system is needed to diagnose why the dirt is getting in.
After verifying the cause of the problem, you can check the rings for wear by either checking the pressure in the crankcase or do a cylinder compression check.

In an oil test there are silica chrome an iron?
If there has been a detection of silca, chrome and iron in your oil it could be of two things. Silica typically will be coming from your air cleaner. Chrome and iron typically come from your piston rings.
How would a technician verify the the cause for silica chrome and iron in a oil sample?
it would be verified by the oil sample, the tech would then look at the intake system for leaks or breaks, being as silica is dirt/sand. chrome and iron are piston rings and liners and this all would be found in an oil analysis.

A technician is performing a preventive maintenance check on an engine using the current oil analysis he finds that there is exessive silica chrome and iron listed that components would be involved?
Silica is usually present from one of three sources : Dirt - such as microfine sand (silicon dioxide): Check your air filter Silicate - as in sodium silicate : a component of some radiator fluids : check for possible radiator leaks back into the engine oil. If the oil analysis is also showing high levels of moisture or elevated glycol levels then a busted head gasket or cracked head is a possibility. Silicone - as in gasket goo : once again - possible head gasket breach. Chrome is usually present from "hard chrome" faced parts. I'm a chemist, not an engineer, but my guess would be a chromed bearing or hard chromed crank or bore. Iron is everywhere - but if you are finding lots of it in the oil it will come from either corrosion (look towards the cooling system again) or erosion (stripped from moving parts - bearings, crank or piston sleeves being the most likely wear areas).
How would a technician verify that there is silica chrome and iron in your oil?
silica is a result of dirt and debris that are microns in size passing through the air filter. chrome and iron result from wear created by the debris making its way through your engine and passing through the combustion chamber, making its way past the rings into the crankcase. in order to test this you would want to fully inspect your intake system for leaks in the gaskets, cracked intake, bad turbo, etc. after inspecting these items you would want to run a compression test to inspect ring wear without performing a full engine tear down. also check the pressure in your crankcase and you can determine if its time to tear that puppy down. hope this helps my fellow future techers. -Wyotech Student-
My 100 cc iron head 1973 leaked motor oil into the primary case how can this happen?
Harley dose not make a 100 cc iron head engine.
What chemicals were used to make an AK-47?
Stainless Steel, Spring Steel, Iron, Wood, and a bit of Motor Oil.
Silica is it an oil based product?
No. Silica, or silicon dioxide, is acquired from common sand. In nature it occurs as the mineral quartz.
What is pronto motor oil?
A Cheap motor oil
Does iron float in oil?
Iron will float in oil in most cases. However, for iron to float in oil, it must have a density which is lower than the oil.
Is oil a mixture?
The oil is a compound, the additives make it a mixture.
