All right, I got this header in the condition it's in. The PO thought it would be a good idea to silicone the tubes into the collector. Add a few years of rust and they don't want to come apart.

I have tried,
Soaking in penetrating oil for a few days
Heating
Beating
Some acid I have (unknown type)

Still stuck, Need to get coated.............. Any ideas?

WD-40, Lacquer thinner, Acetone or 3M adhesive remover.

I ran across this, this morning regarding penetrating fluids:

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.

I have a spray bottle full of ATF in the shop and it works wonders.

You know, diesel seems to be able to weep though just about anything.

If all else fails, there is always the Thermo Nuclear Warhead option. Or just go buy a new set.

What I was thinking, I guess since Naval Jelly is too thick then Jasco would be out of the question, that stuff is NASTY!!!!
