Hi I'm a novice mechanic with a problem.

What would be the best way to remove this rusty stud?

Start with heat and penetrating oil. A propane torch should work. Just make sure you aren't heating anything up that contains fuel. Use Liquid Wrench or PB Blaster for the penetrating oil. They do not catch fire as easily as WD40.

Apply the penetrating oil & let it soak for half an hour. Apply heat for a a couple of minutes. Let it cool some.

Repeat 4 or 5 times then use some vice grips on what remains of the stud.

By the way, there aren't any fuel lines near by are there?

There was but I removed them to have more room to work.

Just make sure there is no residual fuel nearby if you try heat. If you have an air compressor, blow out the areas that had fuel thoroughly to prevent vapors from hanging around.

I have found Kroil to be my favorite penetrating oil. As others have said, combine with heat and patience.

One quick comment on the opposing stud- the one on the left of your photo that is not visible. Don't chase this one unless you pull the valve cover and capture any shavings. This stud goes straight into the timing chain area. Any metal shavings you create from chasing the threads get pushed into your engine. You can also bend your chain guide. Don't ask how I know this.

I just had this happen myself. I soaked it with pb blaster & then used vice grips to back it out. Just take your time!!

Thank you guys so much! With some heat and some pb blaster it came right out!
