Charles, They can be cleaned with upper lube and other chemicals. John Hervey -----Original Message----- From: dmcnews@xxxxxxxxxxxxxxx [mailto:dmcnews@xxxxxxxxxxxxxxx]On Behalf Of Charles Major Sent: Tuesday, July 26, 2005 10:28 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Build up on valves "while in there" I am in the valley of death and can see the valve tops, man they look bad for a car with 800 miles. I have had fuel problems before and remember lots of spitting and black smoke before the fix. Can I de-carb these puppies? I am doing the water return pipe, but what else should I do? Was running with slight miss which started all this: Tune up, filter, injector cleaning, and vac hoses.
