1. Yes a coolant leak (sodium and potassium) causing liner corrosion (iron). Customer should pressure check cooling system. 2. Yes dirt ingress causing ring wear. Customer should check air induction system. 3. Correct for dirt, but where do you think high lead and tin are coming from and how do you think dirt is getting down there? It's not through the air intake as the chromium, iron and aluminium all normal. So how else could dirt get in.
Hi Leaded paints are less common in the western world but depends where in the world you are. Tin is also used as a marker additive by Quaker lubes. However apart from that odd case it's not additive. Lead and tin come from the bearing. Which is tin flashing. Then lead and finally copper. So it's an early stage of bearing wear. The silicon in this case isn't from the upper cylinder air filter etc as you would also see upper cylinder wear. Instead the silicon is likely dirt or sand from a dirty top up or a new component being fitted which are cast in sand and is often difficult to remove even when cleaned by the manufacturers. I have seen this with many engine manufacturers new and sealed parts fitted by the OEM.
Wow welcome back 🎉...
Thanks. What would you like my next article / video to be on?
Nice one Adam. Superb graphics and information
Thanks Simon, I actually had the idea for the video during covid, but never got round to it. So thought would stop procrastinating and actually do it.
1. Come from coolant of piston
2. Piston ring have dirt
3. Dirt

@@OilAnalysis Ok, let me try
Lead - comes from industrial paints and primer
Tin- May be present as an oil additive

@@OilAnalysisThanks for your thorough explanation. This will help me to understand more about oil analysis.
