Customer Question

hi, i have a 2004 rav4 2.4l vvt-i it's been a great car until last week. it started chatter-knocking loudly.so i towed it home. doesnt sound like a rod knock , but like if you rattle your tounge agenst the roof of your mouth. so i pulled the oil pan and there was a bit of sludge and an excessive amount of both steel and aluminum fine grindings. i couldnt see the crankshaft to see if it were the main bearings. although the timing chain was lose,and all the teeth exhaust cam sprockets have chips at the point on sprocket.so i replaced the exhaust cam sprocket,the cam chain tensioner,chain guides, and timing chain. and it has the same noise. we bought the car used from my uncle who is lead sales agent at Walnut Creek Toyota. Anyway, whoever reads this , i appreciate your help.. thanks
