Silicon (no e on the end) can get into an engine in a bunch of different ways. What you are likely referring to is silicon from dust, which gets into the cylinders because of inadequate air filtration. Some small percentage of this gets in the crankcase via the blow-by gassed that get past the piston rings.

In any event, read this for more information on silicon in an engine oil analysis. It’s not always necessarily bad news.

Hmm.. now how would fine dust from a failing cat end up in an oil sample?? I understand that silicon isn't necessarily from lack of filtration. Blackstone is who did my sample for me and we discussed the high level of silicon in the sample. The reason I asked about silicon from poor filtration is because it would enter the oil sample in the same way the silicon due to poor filtration would.

Read Dan's explanation.

As to the car not being able to run. Come on over and I'll show ya. Mind you that this time it didn't completely collapse as it did the last time. But as I pointed out, the complete collapse the previous time caused the engine to shutdown completely but it did start up and it did run with a plugged cat. And I'm done arguing this point. You should move on as well.
