I have a 2002 Chevy 2500HD 4x4 with a 6.0L anyone have a ticking or tapping noise from the engine?

Answer 1

Good God, don't change to 10w40 or 20w50! Use the grade recommended in the manual or the oil filler cap (10w30, IIRC).

Answer 2

I've had mine since it was brand new in 2003... it's not the HD, but the engine and 4x4 is the same. It has 250,000 mi. and it has had the "cold tick" since it was brand new. Back then it was a bit of a hub-bub 'cuz they all did it and the official word from GM was that it was "cold piston skirt slap". The lower part of the pistons, the "skirt", if you will, was longer/taller than earlier models and mostly when the engine was still "cold", the piston skirts would slap against the entrance to the cylinder until things warmed and expanded. Everyone bitched, but GM guaranteed that it would not effect engine life. I changed my oil every 500 mi. for the first 2000 miles, then started using Mobile1 5W30 every 10,000 mi. for the first 50,000, then went to every 20,000 miles. I tow a 9000 pound fifth wheel trailer for camping and with the 3.73 gears, I get about 10 MPG when towing... 16 MPG when commuting 106 miles a day.

I realize this thread is 7 years old... but I couldn't resist... I LOVE THIS TRUCK!! word of wisdom.... undercoat or somehow seal the interior bottom of the doors. That is the only part that is wanting to rust, and it's from the inside out. Can't *****... this is Cleveland, Ohio where the phrase,"dump or spray a million tons of salt" is the road workers mantra for 4 months out of the year.

I'm glad I took good care of this truck. Lots of wax and 2 or 3 washes a week during the winter months. With this economy and a new one going for close to $50,000...it just has to last me another 10 years until I get to retire. Uh-oh, just looked at the debt clock...17 trillion... better make that 20 years until retirement.....

Answer 3

DO NOT USE 10-40 or 20-50 IN THAT ENGINE YOU WILL DESTROY IT. The ticking sound is it a light or heavy sound. If its light than that's okay but if its a knocking sound than that's bad. If you have the know how than I would put a magnet on the oil filter.
when you change the oil take out the old oil filter and cut it open be careful if you see any metal in the oil than you need to get your engine rebuilt. but if your car is getting good gas mileage and has good acceleration than I would not worry about it. Some cars come from the factory like that and their fine.

Answer 4

The ticking noise is most likely your valves. It is fairly common, but you might want to check with Chevy to see if you are eligible for any Recall Repairs. They are usually free. It could be an exhaust leak, but the valves are typically loud on the newer Chevy 8cylinders.

Answer 5

First of all, I love the skirt!!! People tell me I've nice thighs but I still don't wear shorts

Answer 6

I love long dresses. My bf loves the short ones. So my closet is filled w/ 1/2 and 1/2.

Answer 7

what oil are you using, I assume it isnt in warrantly, check online for recalls,

if you are using a light 10w-30, I would switch to a 10-40 and see if it goes away,,, I personally never use anything less than 20-50 Catrol in any of my vehicles, which now total 7,, two classic Jags,, Three BMWS,,

Answer 8

I have had several of the small block Chevy's in the past few
years that have had stuck/noisy lifters...
Put some additive in the oil for noisy / stuck lifters...

Answer 9

Valve adjustment needed or collapsed hydralic valve lifter.
