Hi, we just bought a used 2001 XLE V6 Carmy and I was dumb enough not to do enough research on it until I actually bought it. Anyway, everything is great with this car that we bought with 43,000km on it and I have the complete service records including the oil changes. Anyways, I opened up the oil cap on found some sluge on the inside cover. It was not on the cap (it might have been wiped off earlier) but the sludge was enough for me to scrap it off with a cloth with my fingers. Anyway, it was not too bad but I wonder how it would like with the valve cover off? I would say the inside cover was covered with about 1mm of sludge or so. (it feels like sand)
Also, is the Toyota Canada sludge problem warranty good for Canada as well? I believe it's the 8 year unlimited milage warranty on the sludge problem. I do not notice any blue smoke on the exhaust and the oil dip stick looks clean.
Should I be even a little concern with the amount of sludge I found if I continue to do my regular oil changes at 5000kms? Would the sludge go away with more frequent oil changes?
