Stripped Pan Head Screw - Cylinder #6
 

Hi All,

I have been dealing for 2 days with a Stripped screw, I was doing the tune up on my Porsche Boxster 2002 with 100,920 miles and I found on the Cylinder #6 the top screw that I can't get it out so I put my cellular to view as a pic or video why it wont release or unscrew and I found that the pan head screw was totally stripped..... I'm very frustrated because I have been trying everything I can, right now I'm waiting for some tools to try.

If you have the same problem PLEASE let me know how did you solve it or how did you fix it.

Regards.

If that is a coil - then that should be a torx screw!
Sometimes an allen wrench will undo a stripped torx screw.

Drill the head off, pull the coil off and then there should be no pressure on the screw to come out with your mole grips.

Cut a slot into with a Dremel and use a regular screwdriver turned with vice grips.

It should be an Allen/hex, not Torx.

An Irwin (or equivalent) bolt extractor should also work for that. Then replace the bolt when reinstalling the coil.

Looks like you have decent contact on there with the vice grips... How torqued down are those screws? If you can get a 1/4 of a turn on there and break the tension, rinse and repeat that step one or two more times, you might be able to then simply back it out by hand. I had a similar situation with a cam-shaft position sensor on my BMW a few years back and the aforementioned process did the trick.

Good Luck!

Hello gomjo, what works for me most times in this situation is a hammer and a good centre punch. Pop a nice indent on the crown then angle the punch and gently tap with the hammer. This will only work of course if you can get in there to do this.

I've used probably all of the methods here at some point in my life.

I had to use an extractor to get out one of my lifter carrier bolts (which is also a socket head cap screw) and it worked well. It's not perfect and you need to get a really good bite on your first try or you'll just chew more metal.

If you're on a road trip you don't have an extractor. So...

Jamesp method of using a dremel to put a slot in it will work every time if you can get access with the dremel. In the case of my lifter carrier I likely would have nicked the carrier and that's not a place one accepts collateral damage.

One of my all time sure fire methods to remove a fastener which is FUBAR is the one suggested by derfo. A good punch and a hammer will remove any bolt, any size, anywhere. I learned of the trick 30 years ago in the VW manual for the complete idiot and it flat out works.

A surprising number of times the fastener will still be useable (if you're in a jam. I'm not suggesting an OCD Porsche^tm owner ever reuse a fastener. Strictly mad max here). Like the dremel method, getting a good angle on things.

+ 1 ^^^

most likely you will not have room for the chisel and hammer trick, therefore I would try the dremmel approach...

which grip recommended for head screws boxster 986

Buy a cheap torx bit of the right size and DRIVE it into the head of the bolt like a nail. It will grip the rounded out hex and allow you to remove the bolt.
