does a consistent rpm when breaking in a truck matter over the life of the truck?. for example: if i keep my truck consistantly around 2000 rpm while breaking it in, will it prefer or perform better at that rpm. and will it loose a lil "pep" because of it. i try to maintain good mpg's but dont want to make my truck whimpy.lol if thats possible...... sorry for the essay
The engine doesnt 'prefer' a certain RPM aside from your power band where you make the most of your HP and TQ's. Engine break in is required(most people drive their cars like they stole it from day one) to insure the seals, gaskets, and rings heat up properly and wear to each other in a relatively 'calm' environment.
The unspoken rule of engine break in that Ive understood from mechanics and from my own experience is dont consistently rev up to red line or around, and try not to punch it till you get out of the manufacturer's suggested break in period. The way I see it is, take it easy for those 1000-1500 miles, then treat it like crap. To each their own though.
Id say you have an engine issue, personally Im not too knowledgeable on these engines so I couldnt tell you if its nothing to be worried about. If YOU dont feel it sounds right, bring it in, thats what matters, then have them explain what is causing it(could be a number of things) since you seem interested in what is causing it. Could just be you have loud ass valves.
