Engine not firing. Maybe the altenator?

Putting together this 347 for my Mustang was about to put my water pump on when I saw this line in the timing cover that has me worried.I don’t think it’s a crack it almost looks like a seam from the molding. It’s just not the same surface as the rest of the cover but I would definitely like to get some other opinions before I go any further. Appreciate the help!!

So I recently upgraded my 2015 Jeep Patriot from regular brake pads to performance brake pads because I wanted to make it a little faster without having to mess with the engine.

It's been about two weeks now and honestly I'm not noticing much of a difference in speed. I figured since they're performance brakes they would improve the performance of the vehicle but it still accelerates pretty much the same.

I'm starting to wonder if maybe they have to break in first before you get the full horsepower out of them?

Also, I've noticed they've started squeaking pretty bad lately, especially when Im reversing. I'm assuming it's because the new brakes are dry since they're creating more friction.

I was thinking about putting some grease on the rotors to help everything move smoother and hopefully get rid of the squeaking, but I don't know which kind is recommended for performance brakes.

I haven't put anything on them yet because I don't want to use the wrong stuff and void the warranty.

Would appreciate some advice. This is my first time upgrading anything performance related on a vehicle.

Or possibly a new spark plug.

Guys, I noticed I don’t have any mufflers. Maybe I lost them from backing in like this. How am I going to get home now? Can I drive it like this?

Hey quick question do you think I should make the repairs on this or get rid of it and get something new? What repairs do you think are major and should be done right away or can wait? Any helpful answers would be greatly appreciated.

ordered REAR brake pads for my Honda fit 2010 by mistake instead of front from rockauto.
came back 1.5 hours later and the mechanic says it’s the wrong part.
im not paying mechanic price for parts so i plan on keeping these.

how much longer can these last me?

Gonna throw plumbers tape and a new clamp on this one, should be good to go?

Laced up .. send it ..

Wife said she heard a grinding noise 🤣
