Default Help Identifying Part On Which I Accidently Broke a Bolt

Hello All,

While installing my TBW skid plate I mistakenly tried to remove the wrong bolt (newbie move) and in the process broke the bolt while it was part way out (even more newbie).

I'd love some help Identifying the part this bolt belongs to based on the pictures I have below. It is directly inside (towards the center of the car) the drivers side front wheel and behind the fog light area. If its something vital to the health of the vehicle I will certainly make an appointment to bring it into the shop ASAP - won't be driving it over the next couple days anyways.




Thanks in Advanced,
DGM

Looks like the valve cover. If you do drive it, it'll probably leak oil.

Agreed, valve cover bolts.
They are shoulder bolts, this means most of the length is larger in diameter than the threaded end. The theory is to snug the end of this larger diameter against the surface so you don't overclamp the seals.
Torque is usually about 10ftlbs.

You may need to remove the whole cover to work on the broken bit.

ugh
so the end is snapped off in there?
that's going to be a nightmare accessing the area to get it out if it's broken flush

As mentioned above, you will likely need to take off the whole cover. This should get you a good 1/4" or 3/8" of bolt to work on. Hopefully. Otherwise... That is a giant PITA to get an extractor bit in there without pulling the motor.

Looks like the bolt won't be flush once you take the valve cover off. Hopefully that's the case. If it's sticking out a bit you might be able to get it to turn with some vise grips. And if that doesn't work, maybe dremel a slot in it and see if you can turn it with a flathead.

How did you break it? Did you tighten it and snap the head off?

Thanks for the responses all. Seems like valve cover is the consensus, though no oil leaking so far.

Yes, the bolt is currently snapped in there and broke when loosening it - I had misread my instruction diagram and tried to remove it thinking it was necessary for the install.

Here is a pic of the part that broke off:



I'll make an appointment to bring it in to the shop ASAP, I wont need to drive it for a week or so anyways and don't want to drill the broken bolt out myself.

OK, not a shoulder bolt.
As mentioned, there may be some bolt sticking out once the cover is removed. I would pull the cover and see.

Thank you for your responses, Charlie, much appreciated.

I've got an appointment to take in to the shop a week from today. Hopefully it doesn't give them too much trouble.

I accidentally snapped a valve cover bolt in the same location when I was putting my engine together. I already had the engine in the bay so there was no way I was going to pull it out again. I ended up putting some grey rtv on the bolt and slipped it back in. I have a little over 3k miles on the engine with no leaks at the bolt yet. I will have to pull the engine again at some point and mess with it, though.

This could be a good option for me going forward. If they do say they'll have to pull the engine to get it out, I'll probably go with this route. I took a test drive yesterday to see if any oil is leaking. Still nothing - so perhaps just sealing it is the way to go.

Based on this thread and my supplemental research, as I understand it as long as the car is not leaking oil it is not damaging to the greater health of the vehicle. Am I correct in that assumption?

Pretty much. Just keep a good watch on the oil level and remember to check the area where the bolt is broken. Also, I am nowhere near stock pushing around 340whp/370ftlb, and it has been holding up for now.

Thank you for the information and context. Very helpful.

Just wanted to post the conclusion of this issue for anyone who may come across this using the search function.

I had the broken bolt extracted out by the dealer. I explicitly told them not to pull the engine, knowing that I could just seal the hole as per the above method mentioned because there was no oil leaking.Luckily it never got to that point and they were able to get it out with an extractor bit. Total cost for the labor, parts and taxes was $130.

All in all a high price to pay for a stupid mistake, but one that I was happy to pay for the peace of mind and long term health of the vehicle.

Well, yes, it sucks.
Well, yes, most of us have done oops before. It's called learning.
For a dealer price, not too bad.

"You can't buy experience, but you sure do pay for it".

Glad it's fixed and thanks for the update.

No Doubt. I saw similar threads where the engine needed to be pulled and costed upwards of $500, so I was relieved to hear it was fixed relatively painlessly.


Thanks to you and all for the helpful information throughout.
