Call one of those paintless dent repair guys and have them come out and give you an estimate. If they're really good, they will show you photos on their website or google page of their work. Good ones around where I live can fix that. Then you might need a little paint correction, might not.

My daughter backed into a tree the other night, a $4K bill!

Well I screwed up yesterday morning.

I usually back into the driveway but when coming back from taking my daughter to school I pulled in due to it being trash day and I had my cans at the end of the driveway on the left and my neighbor had his on the right between our driveways and it was just easier (I had 3 containers and neighbor had 3, trash, recycles, yard waste).

A bit later when I went to leave for work the trash truck was there emptying the cans so I sat there for a minute or two waiting while watching in the rear view mirror. The wife's Acadia was parked behind me to my left and I actually forgot that she was off work (she's usually already at work) so when backing up I started to move to the middle of the driveway to avoid the trash cans and hit the Acadia.

The Yukon's driver rear panel just behind wheel well.....

Acadia passenger rear at same area....

View attachment 383860

It's mostly just paint damage, but there is a small golf ball sized dent on both vehicles. Right behind the wheel well on the Yukon and right on the wheel well lip on the Acadia.

Don’t feel bad I backed into the same passenger side rear and busted out two sets of lights within a month or so of one another first was a tree second I forgot I had my little trailer behind me at a angle to back into the front yard and leave and jack knived it as soon as I moved View attachment 383863

I feel your pain. I did almost the same thing with thecopcar and my exs white fjord a while back. Rear edge of the wheel well And near the tail light.

Well - Since we are having an inpromptu meeting of the "I backed into my family member's car" support group....

A few months ago, I just got done telling my two older boys that they need to pay attention to what's around them when they are driving and went out to move Julie's Yukon out of the drive way. I then proceeded to take the rear passenger corner of the Yukon and push it into the front drivers corner of the Grand Marquis. Pushed in the bumper cover pretty good, but avoided any sheet metal. :banghead:. Had to replace the headlight assembly on the Grand Marquis as well.

So many dents here I’m getting angry, gotta go. :laughing1:

I luckily haven’t done anything for so long I can’t remember, at least as far as running into or backing into anything. There was this incident a year or so ago where I didn’t have my front wheels turned straight ahead and hit the switch to air out my Silverado. I hit the stop,switch as soon as I heard metal starting to crunch and was able to stop it before it was bad. I’m pretty sure a PDR guy can fix it and in reality it’s kinda nit noticeable unless you look at it from an angle. It’s a reminder to me also…don’t hit that switch unless you’re sure the tires are in tuck position.

Took Kin to get her nails done for homecoming tonight. Some spirited city driving ensued. After dropping her off, I tested for sustained high load and RPM. Again, all seems normal so I'm gonna call it good. I might have hit a new speed record but I can only guess the actual speed. 5,700 RPM, 3rd gear (1:1), 3.73 rear gear and 31.9" tire calculate to 145MPH. But it's not quite that due to the converter slip. Should be right around 135, though. Judging by the needle's movement up to 120 and the time following, maybe it is closer to 140ish.

What y'all think?
That thing pulls like crazy at the upper end still... Nice job man.

How fast was she going James? This the pickup you guys just bought?
She was only about 20-30 feet in front of the tree when she started backing. I reckon that she just let it roll and didn't press the gas. She was crying as she was just leaving our friend's home, the folks who lost their daughter in the Tesla crash. She said she didn't hear the back-up sensors, or look at the camera, so it must've got up to 5-10 mph at least.

I got 4 estimates, all about the same, they all keep using the wrong part numbers, I was going to keep it out of the insurance but we have accident forgiveness with Geico and am going to pay the difference for OE parts and chose my own repair shop (GMC) so I'll have more control over the repair. So that will save us some money.

Now if I can only order parts front vendors that are not broken or missing for it!

Took it apart.


First look as soon as I removed the head:

View attachment 382966


The complete ring where just the carbon is knocked off shows that the valve was riding the piston for a little while. This must've been during that time when I was cruising, had just noticed it and was trying to determine if the odd vibes I was feeling were from the driveline or a loose wheel. It was the steady rhythmic pulse of a dead cylinder. Had I known, I would've shut it down that instant and all I would've needed was a new valve spring which would've been a 3 hour fix on the side of the road to get me back home with no damage at all. But, at some point, the valve and piston had a disagreement and while the piston was trying to buck the valve off it's head, it bítch slapped it sideways, leading to the hoof marks in the piston:

Pulled a valve from a junk 706 head for comparison:

The head looks fine. It looks like it did little more than just knocking the carbon off. I don't know how it survived, but the guide looks and feels fine, too:

View attachment 382969


I buffed the carbon off the piston and smoothed the hoof marks to eliminate sharp edges that would lead to hot spots. The light reflecting makes them look more severe than they really are:

I pulled the lifters from that cylinder and they look fine. Plan of action is to clean up and install that salvaged valve, replace all 16 springs, reassemble and send it.
Play the lotto tonight!

Finally fixed that exhaust leak on driver side rear with dorman clamp that took soooo much pain to install.
I couldn’t get manifold removed from pipe so had to resort to clamp.

And i think the brought back some horses on that 6.2.
We were accelerating on highway and at around speed of 40 i removed car in front is doing that too slow so i kicked down the pedal and some stuff went flying and coffee got spilled.
Wife was not amused

Made some progress on my recently purchased Burb.

4x new Geolanders to replace the dry rotted crap that was on there.

Alignment.

New front discs and pads. Plenty of meat on the old ones, just rusted to hell.

Disc and pad change on these trucks are super easy :)
