Looking like I'm doing the AFM delete sooner than expected.

I recently got a 2007 Envoy Denali with the 5.3 and 4x4. We drove it about an hour home, no ticking. Drove the next day for about an hour, no ticking. And then later that day I went for a drive and all of a sudden the engine sounds like lifter tick.

I work at a chevy dealership, so I had my friend who is a tech check it out and he said its lifter tick and from the sound of it, the cam might be chewed up.

I've been planning on building a seperate motor on the side with AFM delete, but later down the road. Looks like I'm going to have to have it done now. Going to ask around tomorrow and see how much I can get the kit installed for. Because that way I'll have almost a rebuilt head (hoping the springs, pushrods and rockers are in good shape). The Envoy has 147k, so I figure they should be good.

The kit is from Texas Speed, it was about $570 configured for me. Thinking about getting a new waterpump just because for preventative maintenance. Even tho I'm going to be broke after all of this.
