The head tanks on our P450 are made of aluminum. Fortunately, the forward tank is not used much and is readly accessible. However, the rear tank is heavily used and not accessible. The tank has developed a heavy crust on the bottom and I suspect a leak. The options that require a new tank are all going to require heavy construction. Is there anything else I can do to address the sludge and determine if I have a leak?
