WOW, you used locktite when people normally use anti seize on those bolts.

 

I can buy mek at most stores here..

 

You guys are all "OMG" Blue it the easy to loosen one lol. It's made for being able to take out later just not work itself out. I would try the heat idea is any sticking out at all?

Locking header bolts are your friend

 

So I take it that means you were in the Navy, in some sort of mechanical job. Did you ever use a penetrating oil called oil of wintergreen? My dad used to use that when he was in the Navy and he said that it only takes a drop or two for the bolts that looked like they hadn't been removed in 20 years and were exposed to ocean air for that whole time.
I found out that it is toxic when I went googling for some and I told him about it. He thought it was pretty funny when I told him that they keep it under lock and key and you have to sign it out when you need it now a days because when he was in the Navy they just kept it in an brown bottle on an unmonitored shelf.

AIM, is there enough sticking out to get a wrench on? I found out a little trick the other day on a camaro forum, If there is enough sticking out then you can grind flats on two sides with a dremel and use a wrench to get it out. I did that on one of mine on the camaro and it worked well. I figure the rust on that bolt is about equal to blue loctite on newish bolts. The loctite might already be broken down anyway, at idle your manifolds should be sitting around 400º. My headers on my 5.2l and my dads manifolds on his 5.9l are that temperature at idle.

 

I played Bo'sun Mate for a while before moving to Data Processing. Never heard of the "Wintergreen" stuff, but my Marine Corps brother brought home some stuff called CLP that the jarheads used for cleaning their weapons. It does a better job of freeing stuck fasteners than WD-40, which my dad will buy by the gallon. I wised up about 15 years ago and told my dad that WD-40 is total **** and to use PBlaster. I've since been informed by people that Kroil is the absolute BEST for rusted fasteners.

 

Any real mechanic will use vise grips on the bolt and heat to loosen the lock tite.

 

I used loctite because those little F'ers continually back out on me and loctite usually works wonders holding them in. perhaps lock washers are in order.

The spare bolt must have been weak as I only used a closed end wrench on it, The unset loctite does act as a lubricant though, and might have allowed for more torque than I thought possible on a hand wrench.

 

Your just too damn strong. Better put down the wrench

 

prob over 25 yrs ago or so but i remember dad used to get the bolt cherry red and then throw a cup of water on it...that was on the really stubborn bolts...it never failed him to the best of my recollection

 

Maybe I should use my left arm. The right arm is stronger from constant master....
