engine damage?

[mobilaltima]

A few weeks ago I was at a complete stop at a yield sign in my Ranger and i got rear ended on the driver side by an F250 that was going about 10-15 mph. Bumper is dented a little, the bed has a small dent and I had to replace the tailight, the frame isnt bent, and otherwise the truck runs and drives fine. I only paid $1000 for it and got more than that from the insurance so I'll drive it as is and put the money towards something important. My concern is, when i got hit, out of panic, i threw it into neutral (its a 5 speed) and while trying to look back to see what happened and trying to get out of the way(had it in neutral, obviously wasnt going anywhere lol ) i hit the accelerator instead of the brake and kept it at redline for about 5-7 seconds till I calmed down and realized i wasnt on the brake and that everything was fine. I dont remember what the redline was 5k rpm or so, but Ive put 1000 miles on it since then with no problems. But the thought still lingers in my mind that I may have damaged the engine. So, could I have caused any damage for it being at redline for that long? Its the 3.0 vulcan V6.

Also since the wreck, Ive noticed that the driver side of the bed sits higher than the passenger side slightly and the body lines on the driver side dont match up, obviously from the wreck. Would unbolting the bed and lining it all back up correct it or might there be other damage causing this?

You could hold your foot there all day and not do any damage, the computer would prevent it from over reving.

Your engine should be fine.

While all day is far over exaggerated(fuel cut off on earlier stuff is 6250 RPM), I doubt a few seconds would harm it... Yes most any std performance engine will be in pieces if held at 6250 RPMs for more than a few minutes...

In neutral a Vulcan is revv limited to 4k, at least automatic transmission ones. As your is MT, maybe isnt limited and it went to 5k rpms, then you just cleaned you intakes pretty good.

No worries, drive as normal

Not necessarily. Youtube Engine Blow and watch cars with bricks on the accelerator bouncing off the rev limiter until they blow. It will save you from the accidental rev but not limit long term damage when held wide open.

A short flirt with the limiter won't hurt a thing a properly maintained engine.

If you haven't noticed anything wrong in 1000 miles, I think you can rule out engine damage. Since you've already been paid, it's essentially a free car. The bed is bent, live with it or spend money on aesthetics for a beater.

If the rev limiter doesn't save it, the valve float will.

Indeed. You will be fine.

In my younger, stupider days I would routinely bounce the engine in my Neon off of the rev limiter. For a while I had a no-idle problem and out of frustration I would hold the accelerator down for a number of seconds. Usually it would clear up the no-idle problem for bit.

My point is that the car lasted 200k that way and the engine only finally failed due to an overheat that I let go for one exit too long on the highway.

If you're actively rolling the speed sensors will (could) disable your lower, neutral rev limiter. You'll still have the 5500ish RPM in-gear one.

Besides, you made it this far. You'd have a miss if you busted a rocker arm.

Youre good man. Glad you're okay,i assume you are if you were able to post this.

The little Vulcan v6 is one tough engine. It is going to take a lot more than 5-7 seconds at red line to damage it. As others mentioned there's a rev limiter to protect the engine. No harm no foul.

I know this is apples to oranges , there was a YouTube video about a ford aspire where the owner threw a brickon the aaccelerator and let it go. 25 minutes later the radiator blew. 30 minutes later it locked up. 55 minutes later it restarted...

Engines are tougher than you'd think

There's no point in worrying about it; it already happened. Even if it did cause damage, what are you gonna do about it? Just keep driving it and forget it happened.

 

[cptbarkey]

there are probably redneck ways involving winches and trees that could straighten the truck bed. use some creativity and dig up the high school physics equations.

 

[meep]

hard to know if the bed is bent or the frame is tweaked. you need to eyeball it and even measure it to see if it lines up, is square (measure in an 'x' pattern), etc..

engine is likely ok. Sounds like a great little truck.

The engine is fine. Don't unbolt the bed and straighten it, it won't bolt back up. Just got to live with it

engine was running fine until this morning. Got on the road and while accelerating to 70 mph it started sputtering and making a popping noise sounds like a possible intake gasket? Check engine light also started flashing so I drove back home and parked it. I have two codes po301 cylinder 1 misfire and po401 EGR insufficient flow. I say the intake gasket because a truck at work was doing the same thing recently. Well I have to hit the road I'll be back on here a little later on thanks guys. I will start figuring out the problem tomorrow its been raining nonstop for two days here.
