you might try to supercool it too to get all of the metals to contract so if u pull the head off, put some dry ice on it for a while. Another option is to break open a can of refrigerant and spray it on the bolt and surrounding part of the head. Propane works too.


Oh yeah, and if the ez out breaks, weld a nut to it. Unless the heads are steel.

Your best bet is to take the head off unless its a easy location. If its not a easy one to get to you will be wasting your time. Might just have to break down and take the head off.

I wouldnt worry about one bolt, and just use some extra gasket material around that primarie.

it doesnt leak now, so it shouldnt when I put new headers, I am just worried about more breaking off. I really really dont want to pull my heads...that way more dicking around then I want to do, plus all the new gaskets/parts I will break, not worth the price. I have heard about ppl getting them out without removing the head, PITA, but it is possible.

I am going to attack them tomorrow, If I break another manifold bolt, then I might reconsider.

they don't leak now but when you take them off and put the headers on they will.... i even used 2 gaskets around the broken bolt and it still leaked

EXTREME

just a FWIW, when i put the heads back on my truck. i dropped one of the bolts and absolutely could not find it. Ended up not putting it in. Hasn't leaked in 2 years. they are stock manifolds.

oh, and just about a 4 or 5 months ago i found the bolt wedged between the frame and uca i believe, didn't put it in though.

and goodluck on the install!
