Vortec v-6 gmc motor question

[stringtalker]

I have a gmc truck with this engine in it. I put new heads, lifters and pushrods in it about 2 years ago. Now i have a noise that kinda sounds like a noisy valve but i actually think its a bearing in a pulley or something, anybody have any ideas?

Sounds like some serious truck talk.

Nice deer btw!

What year? Hyd. Roller lifters I assume. Have you sprayed any brake clean on the pulleys yet?

Its a 1996, yes roller lifters, i replaced all of them. I havent sprayed anything on anything yet

Give each pulley a little shot while its running. The bad one will shut up for just a sec if that's it. The idler is normally the one that goes out. Those Hyd roller lifters are normally bullet proof pushrods are either good or bent, curious as to why you had to change em?
