Anyone knows what made the marks in the engine bay?

No droppings means it's probably not mice. The shit constantly. The paw/claw marks on the battery look like squirrels or similar sized rats.

 

Looks like Langoliers to me.

Let me guess. Your soda lost all carbonation and you hear a constant crackling sound, like kids cereal.

 

Definitely leprechaun tracks, very distinctive...

 

maybe a rodent.

maybe a mongoose

maybe it's gremlins...

 

Yup, and he’s laughing at OP…LOL

 

Damn this is your new truck, now you’ve got small thieves coming after it?! Hope you get them this time.

 

As most are saying you have a rat infestation in your area. It will only be a matter of time before they start chewing up wires.

 

Lol come into the 20th century.
I did what you did back when you had to do that... In the 70's and 80's. Now? Stuff don't usually leak or burn anymore. Waste of time unless you need washer fluid. I check mine every oil change.

 

I know your words speak truth, but I just can't help it. I can hear my father speaking from the grave, "check your fluids and do your maintenance!" And 10 years running submarine nuke plants doesn't help.

 

How many of those did they build and how many parts? I understand though. I still do some shit from habit but I broke myself of checking every fill or every other fill.

 

I assume your question was about the navy nuke plants. Short answer is a bunch of them over the years! There is / was one on every nuke sub built since the Nautilus. And the surface nuke ships had multiple reactors. And each big nuke carrier had quite a few of them.

 

Mouse testicles

 

Yea but not 25000 a month and the number of parts were a lot more than a Tacoma. That was my point. You do you tho. I am cleaning my engine this weekend.

 

That's for sure a rodent, stay on top of that or you could wind up with one hell of a headache.

 

A Gremlin

 

Second picture looks like it could be DLA. Or it could just be imperfections in the plastic causing dust to form in weird shapes. Highly doubt those are animal marks.

 

the ones on the battery and hold down most definitely are

 

Best to address the problem early so you don’t have damage like on this other thread.
