Looks like I'll be learning how to do a timing chain, or at least guides and tensioners on my 4.6.
My truck has sounded like a diesel pretty much since forever. I really had no idea what it was, but I'm sick of listening to it. It's getting worse. It really sounds more like a metal scraping noise now. It just makes this nasty scraping noise until I hit about 50mph.
I believe that it'd be the chain. It makes sense. But I will run it by an exhaust shop before I start wrenching on it. I am pretty tone-deaf when it comes to engine and vehicle noises.
So when I tear everything off of the front and top of my engine, what other upgrades should I think about doing? New pullies? Cams? Hoses, radiator, vacuum lines? Intake? Throttle? PCV, EGR? Heads? Full overhaul...?!
This will be just about as far as I have ever torn down my engine, and I don't mind going a little further if it's worth it.
The shop told me it's about $1,800 to do the timing chain, which sounds about right to me. I know it's a lot of work. He said I'd be better off just dropping a new used engine in there. But it's already running a replacement engine that was put in August of 2016. I'd rather repair it than replace it.
I am thinking that if I am looking at close to $2000 in parts/ labor, I might as well save the labor by doing it myself, and use some of my savings on upgraded parts/ accessories.
What do you guys think about the job? What other parts should I think about replacing while I've got her skirt up?
