2003 Silverado push valve

When i turn on my truck in the morning it makes a tackling sound my friend told me it was a push valve. I want to know if this right I don't want to spend the money on something that doesn't need to be fixed. I would also like to know if this is hard to fix or is it something I can do myself. The noise is usually in the morning when the truck is cold and after I drive it for about 10 mins. it goes away. Please help.

    your discription sounds like a valve lifter, your friend called it a push valve, basically the same. It is a job, the whole top of the engine has to removed to get at them, wires, hoses, fuel rail,maybe the distributor, once you get the intake manifold off, you'll see the push rods that are sitting in the valves.also the rocker arms need to come off and readjusted when put back together. First off you to find to find which one it is. there's more to it also.

Unless it smokes, you can live with it. I am guessing you have more than 70k miles and that happens.

The lifters get sloppy with age and you may try using 10-50 , or 20-50 W oil which will probably quite it some.

ypically the noise is greater when it is cold and then gets quieter as it get warm and tolerances close up.

Good Luck

Valves in 2003 ford focus SE 2.3L are loose...how do I fix them?


I doubt if the valves are loose or need adjustment as the engine should have hudraulic tappets which adjust automatically when the engine is running. I suggest that your friend take off the rocker cover and see if anything is out of place. As the engine is 10 years old it is possible that the tappets may be badly worn and not working properly hence the noise

03 sorento will only start once a day usually morning


When it won't start you need to find out what's missing , Spark , fuel pressure , an then go from there . If no spark is it a coil , ignition module , crankshaft position sensor , the PCM/ECM - engine computer . If the fuel system is the problem is the B+ voltage to the fuel pump ? Is there a fuel pump relay that supplies B+ voltage to the fuel pump , is the PCM/ECM turning on the fuel pump . The simptoms you provide make's me think a sensor is going bad , shorting out when hot or vehicle is up to temp.

2003 Chevy Silverado SS brake lights aren't working but top cab brake lights are. Bulbs in brake lights are working, and light up when headlights are turned on, but do not get brighter when brake pedal is...


Sounds like the turn signal flasher module has gone bad. It controls the brake lights and turn signals. It is located under the drivers side of the dash. If is a rectangular black box with a grey connector and 8 or so wires connected to it.

Need to restart diesel engine after running low on fuel, on a 2003 Chevy Silverado 2500HD


After putting more fuel in the vehicle
Open the hood
On the righthand side of the engine just to the side of valve cover, back by the firewall you will find a round plunger about 1 1/2" in diameter. The plunger will push down and come right back up on its own. Push the plunger rapidly till the pushing gets firmer or stiff.
Start it up. Sometimes it will have to be done a couple of times. I actually fined it works best to pump it firm and then have someone else start it while you keep pumping it. If you do it this way make sure your body is clear of all moving parts.
This is a very fast way of getting it going
Good luck
