Re: Burning smell 5.7Hemi

I think the break in is just to cover their butts. At my job we get new vehicles every few years and pick them up out of state. From the day we get them we go well over the speed limit, haul heavy materials, and basically treat them like crap because we don't own them. In my 20 years we have never had an engine go out or give us trouble. Transmissions, transfer cases, etc. is a different story.

not exaclty... It says in the manual something along the lines of varying throttle within local speed laws. It's much better to vary rpm's during break in and not keep at the same RPM for an extended length of time. Most people think being gentle means keeping the same low RPM's and it's just not the case. You just don't want to be going into high RPM range and obviously going WOT isn't recommended either. Most motorcycles are more specific and say to vary rpm's between X and X for the first 600 miles.

I am aware of what the manuel says, but based on my experience with 42 cars and many of them new, I have always broken in a new engine "gently" for the first 500 miles, and then changed the oil. That is not saying that I drive it at a constant low rpm speed. I just would never do what the OP did to his car, and would never buy a used car from him either.

What did I do to my car? I have been babying it the whole time. Maybe I wasn't very clear. I am saying that I gunned it meaning I got it up to higher rpms like 5000. I live in Colorado where we have big hills so I was kind of forced the first time to lay into it at around 200 miles to get up hill into traffic. That is when I noticed burning smell. Since then I have given it some throttle to see if it persisted a few times. Its not like I was racing it or running it to redline.

Re: Burning smell 5.7Hemi

sorry, I had you mixed up with the dude that said he rips the crap out of company vehicles.... it reminded me of a co-worker who occassionally liked to drive rental cars in through the exit spikes when he was on company business..

I had that burning smell for a few days too, it went away though. I have about 1600 miles on mine now and I've already done an oil change to Synthetic.

Re: Burning smell 5.7Hemi

Might want to check your shocks. I had the burning smell and thought it was engine break in. After 1500 miles I was underneath checking things out and saw both front shocks leaking. The oil was coming off and hitting hot stuff causing the smell. Had both shocks replaced at dealership and no more smell. Just an idea.

Bah no need. Even some service manuals says no break-in required. How about all those vehicles on the lot that are driven fairly roughly on test drives? I say, drive it the way you intend to drive it. If WOT is your thing, then a "proper" break-in is not going to help your cause

Enjoy the new engine smell, doesn't last for long.

I have the same smell with my 2013 3.6 no engine oil leaks I'm going to check the shocks.

Re: Burning smell 5.7Hemi

IMO more important than driving it like a baby is to do an oil change after the first 1000 miles. The initial run gets so much crap into the oil, I'm surprised this is not the recommendation. Also, for all the engines we build there's no babying it. We heat cycle it a few times and then some wot. We've pulled them apart after 100k miles and they are impeccably clean and are in much better condition then most if not all engines that went through the babying procedure.

Re: Burning smell 5.7Hemi

Here's the bottom end of one after 20k miles and about 60 passes at the drag strip. Ran like a champ, only pulled it apart to upgrade for more power.
