Can anyone tell me when I should get my valves adjusted on a bombed truck. I have a valve or two thats making unusual ticking noise. I can hear it better when you shut the truck off. You know the last second before it stops, after you turn the key off. I have 60k on her now, and i have been noticing this the last 3-5k. Could it be the cold weather as well? Any help would be appreciated. Also, is there a particular setting they need to be at, or factory spects? I'm ignorant to valves.<br>Thanks,<br><br>Kimrey

 

I just checked my valves last weekend. I have 74K miles on my 99 and everyone of them was within 2degrees. First valve adjust.

 

2 degrees? Is that good?

 

I did my first valve adjust with Nail Bender and I had 93K on my HEAVILY bombed (see sig) '99. ALL valves were within spec, although we did adjust the 2 intake valves on #'s 5&amp;6 as they were a little close for my comfort to being out of spec.... <br><br>YMMMV 8)<br><br>Can't hurt to check though, and put your mind at ease!

 

That'd be a couple of thousandths there, NB. <br>Cut him some slack folks, he's a gearhead in training. ???<br><br>I have adjusted @ 75k intervals, but previous trucks have been stock. If I were to put some power in, I would decrease my interval, but only for good measure. This valvetrain ain't no small bolck Chev. <br><br>If you have done this sort of work before, you'll find it to be quite simple. I would recommend a service manual. It will provide you w/all the info, specs, and tools needed for the operation.

 

I did mine at 15k miles when I did injectors. I set the intakes at .010 and the exhaust at .020<br>

 

Ok, now I'm really confused ??? What is best, factory or like spark chaser set his?<br><br>Kimrey

 

I believe mine are well within factory specs

I am also a newbie in training.... <br>BigK is pointing me in the right direction though! ;D

 

I waited until I installed 275 injectors at 190,000+ to adjust mine. They were all within specs, some were about .003 from center of specs. Not bad for the miles. Kenny

 

I did mine at 45,000 miles. All were within spec, but all throughout the spec. I tightened mine down to min. spec.<br><br>Mike
