I put 500 miles on my truck this weekend and had a chance to listen to it real good. I hear what I want to call a lot of top end noise under load. It sounds like cam lobes hitting lifters or maybe valves - kind of a rattling type sound. I'm curious if this is considered normal in a 7.3.

Well without driving it, that is a pretty hard question to post! Did you buy it from a dealer, if so I would ask the service rep to drive it. If not I would have a service rep drive it. The 7.3 is louder than the 6.0, but I love mine and you wouldn't catch me with 6.0. If you really think you have problems, it is always better to have it checked than to destroy the engine! Is there a reason you went back years?? Other than to get the 7.3?? What is the mileage? Did you get a maintanence record?

I went back mostly just to get the 7.3. I love the low end feel of the 7.3 and I don't miss the top end of the 6.0.

This was kind of an impulse buy, so no I don't have service records. The truck has 66k miles on it. I did an OASIS check and I drove it around a good bit and I crawled all over it before I bought it. The only thing I know of so far that I missed in my inspection was the breather. I found some dirt in there after I got it home.

The truck runs very strong, it doesn't smoke at all, I can't say yet if it uses oil, but in 500 miles it hasn't used any so far, and it appears to get great MPGs. I haven't refilled yet, but I'm at 450 miles on half a tank so far.

I guess I didn't hear this top end sound before I bought it - or I blocked it out and ignored it /ubbthreads/images/graemlins/biggrin.gif. I guess I'd like to know if others hear anything like what I'm describing.

From the description, it sounds normal. These things make a whole lot of clatter and clacking and such.

What I notice is ticking and clicking and stuff seems normal. No squeals allowed tho'.

That's really good mileage, about twice as good as mine.

Fuel tanks and senders are sneaky though. 540 miles now it's midway between 1/2 and 1/4. I'll refilll and check the actual mileage tomorrow.
