I would take an oil sample and send it and your chunks out for analysis. I would also cut the oil filter apart and have a look whats in there


Assuming that your entire oiling system (including front mounted cooler, lines, oil tank etc. ) were properly cleaned during your rebuild and it is not some residual material floating around from before or from the cleaning tank. And assuming that your doing a cool down before shutting down the motor after spirited use, I doubt that you would be experiencing coking from this oil. If I thought that I would be contacting Shell about it pronto. Were you or had you experienced any sines of coking previously?

Personally I follow the advice in Wayne's book and flush it all out several times Consecutively with a Dino based oil, changing oil filter each time. Wait till your engine is broken in to run a Synthetic oil.
