i'M GOING TO BURN MY 68

[mwaller5672]

Ok , there was a manifold leak in my 68. I took some out and the others broke. Anyway the stupid manifold won't come of. I cut and grinded for 2 days. Bout ready to cut it in pieces. It's only a 6 200. At the top of the manifold is a silver tube right under the carb. Could that be holding it in place. Would heating the whole manifold help. HELP

sounds like the perfect time for a resto-mod! drop a big old healthy v8 in that b...

[mustang_gt88]

x2 v8 that machine up

You know the bad part. I have a 302 that is carb and a newly rebuilt t5. My wife said I will kill you if you do that. I had surgery on my left shoulder 3 weeks ago and it is really tender every time I do something. I was up half the night so I have to stop messing with it

If the studs broke off and are still passing thru the manifold the corrosion in the hole can be a lot of resistance even if the head of the bolt is gone. When in doubt... pb blast and a bigger hammer/prybar.

I have been using kroil oil. Is that as good as pb blaster. I was just about to start cutting it into pieces to get it off. 3 bolts came out. Only 1 will need to be drilled so far. The rest the head broke off. I had trouble with all 4 studs in the center.

PB Blaster is the bomb. I've seen it break free things I thought would twist off because of rust build up. Sometimes it takes a little while to soak in but in the end it works. If PBB doesn't work it isn't likely coming off. That stuff will free up anything but red locktite and/or pound footage...LOL!

Acetone and Dextron/Mercon III in a 1:1 ratio. Puts PB Blaster to shame!

Pb Blaster is definitely good stuff. I keep a can of it in the jeep in case I ever need it.
Would it be a bad idea to take a small chisel to it and see if you can force up?

[mwaller5672]

I tried the chisel thing. One thing I was wondering if starting it ands heating things up would help

[mwaller5672]

After I hurt my surgery arm I took it to someone. Only charged me 50 bucks but he broke it. Oh we'll. now I have 2clean bolt holes. 2 need drilled and the rest have studs but no heads on the bolts. Does that acetone stuff really work that good. I have soaked and soaked it with kriol oil

Where in the hell did you hear about that mixture?

Where in the hell did you hear about that mixture?

SBF Tech. Juiced Coupe turned me onto it, and it works like a champ! I have some mixed in a spray bottle for whenever I need it.

[mwaller5672]

My final count is 5 to drill and tap. 7 came out. Thats not to bad

I received an email that reads:

Some of you might appreciate this. Machinist's Workshop magazine
tested penetrants for break out torque on rusted nuts.

They are below, as forwarded by an ex-student and professional
machinist, Bud Baker.

They arranged a subjective test of all the popular penetrants
with the control being the torque required to remove the nut from
a "scientifically rusted" environment.

*Penetrating oil ..... Average load*
None ...................... 516 pounds
WD-40 ..................... 238 pounds
PB Blaster ................ 214 pounds
Liquid Wrench ............. 127 pounds
Kano Kroil ................ 106 pounds
ATF-Acetone mix..............53 pounds

The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic
transmission fluid and acetone. Note the "home brew" was better
than any commercial product in this one particular test.
Our local machinist group mixed up a batch and we all now use
it with equally good results.
Note also that "Liquid Wrench" is about as good as "Kroil" for
about 20% of the price.

Good stuff, thanks Rich.
