Guys,

My #7 head bolt is stripped....and I can get a bolt extractor to bite....should I just cut the bolt off with a dremel? (tight space...might damage the aluminum seating too)...I don't have any welding equipment or acetyline torch...any other ideas?....

im guessing you mean you CAN'T get the extractor to bite? if so did you try drilling a pilot hole into the bolt?

Was this going in or coming out? Can you cut the head off the bolt, then pull the head? Might give more access to the bolt.

What do you mean the bolt is stripped, the head rounded off, the threads are stripped, or you broke the bolt?

Describe your situation in more detail for more help, not understanding what your exact problem is.

I have a lot of interest in this thread as well, I'm about to do a H/C swap and this is my first aluminum block project. Everything else before this was 2JZ or LT1 both Iron.

Sure, the bolt is stripped...in other words, a socket, extractor, vise-grip, etc...will not stay on the bolt. Originally it was a 13mm sized bolt head, now its somewhere in the neighborhood of lets say 11mm (with uneven sides). It's in a tight spot.....I cut out my exhaust header to get at it....but it still won't budged. I don't have clearance to drill a pilot hole...seriously thinking of cutting off the bolt head off at the risk of contacting/affecting the aluminum seating...

Ok, you rounded it off. That should be simple. Use your dremel tool to square it up as best you can then a. get one of those sockets with the needles in it that will conform to whatever the size is b. get one of the easy off sockets from sears made specifically for rounded off bolts c. get a 12 point socket that is the closes smaller size and hammer it on the head of the bolt. I've had good success with all three methods.

I like using next size down socket and hammering it onto the bolt then turning it out. Cutting it off would be my last hope.

If the easy off socket is what Stroker2112 is talking about, this coud be a tough removal. If you can't get one of those to bite, you may need to round of the bolt a little more to see if the next smaller easy off will work.

Otherwise, it's gonna be tough to hammer a smaller socket on there. Look at your hardware store for the closest 12-point, 8-point and or internal torx that you might be able to get to grab. Just gonna be tough to get that fastener broke loose!

Good luck & Take your time.

OK, Thanks, its good to hear what everone else has got to work before. I'll try it again either tomorrow or Sunday....dyno isn't for another 7 days... I bolted up a FLT level 5 4L65E instead of messing with the bolt... Once I get the harness, coolant lines, etc, back on...its back to the head bolt. Thanks again,

I am another believer in the bolt extractor sockets. They have a reverse sprial design on the inside so the more you try to loosen the bolt, the tighter it grabs. I have used them DOZENS of times and consider them one of my favorite tools.

The only draw back about them is trying to get the socket off the bolt once its removed.... They get stuck together pretty good. My trick is to get pissed and throw it across the room. Usually when it hits the wall or the floor they seperate Good luck with the install
