Scotty, I drive a 2005 Rav4, with about 80k miles. I recently opened the cam cover and noted that it's got oil sludge/carbon build up inside. What's the best way to flush that out?! Some videos on YouTube recommend flushing the oil by mixing it with gasoline others say with kerosene, etc. In one of Tavarish's videos, he mentioned that regularly mixing the engine oil with a bit of transmission oil prevents carbon/sludge buildup. What's your take Sir?!

Use Liqui Moly Engine Flusher and then put a Royal Purple Oil after you flushed
