1998 Chevy Express V8 Two Wheel Drive Automatic
I bought my Chevy Express this year. Within the first few days, I noticed a tapping noise from the engine. When the engine is hot, and at idle, I hear the tapping. When the engine is cold or hot during driving, I don't hear the tapping. I live in Florida which has very hot summers, and this winter has been cold and I have not heard the noise at all. I think with the hot weather coming, the noise will return. I have been told by several mechanics that I have hydraulic lifters and that they are not adjustable to reduce this noise. They suggested I change oil every 500 miles for 3-4 times to clean out sludge and use an oil thickening agent like Lucas Oil Additive to keep the viscosity of the oil high. The recommended oil for my engine is W5-30 which I always use. The tapping is by no means loud, it is more annoying. Should I be concerned, and how should I correct the problem if that is the solution?
have the same problem?
