I posted this on the end of another thread, but thought it might help a few others out, so I am taking the liberty of putting it on its own thread.

I have had a lot of problems with steel bolts in aluminum intake manifolds, heads and blocks lately. I live on the great North Coast.....we used to call it the rust belt before we went into denial. Salt, water, aluminum and steel ---> a galvanic corrosive mess. I have used all the penetrating oils known to man, Kroil, PB blaster and they work well on most situations.....but not all.


Well I share with Honda-Tech one of my secrets, BigMoose's Bolt Blaster. Just take one part virgin lard and add 9 parts acetone. Mix it up and let the lard dissolve. Apply liberly. Letting it sit a while helps. This stuff will penetrate anything! Note: BigMoose's Bolt Blaster is extremely flammable so use your head. Don't spray it on after using the heat wrench. Keep it away from kids. And only light charcoal with it when there is nothing else flammable around.

Also, in case you do not know this trick. If you have a high strength fastener, like a grade 8 torx drive holding an aluminum piece in an aluminum casting. Like an oil pump in a 700R4 tranny. You can wrench on it all you want and the fastner will break. However if you put the torx driver in, give it a "solid wrap" with a hammer, the fastner will back right out. The shock of the hammmer breaks the stiction and cold welding that goes on between the steel bolt and the aluminum.

Hope these tips help someone.

Thanks, BigM. Where do you get virgin lard (or lard from a virgin)?

 

this stuff sounds good............especially when you live in good ol' canada the rust country of the world.........everything rots here

 

Teken & Earl,

Good questions. This is honestly a hand me down from my Dad. It has been in the "family" so to speak. Dad was a machinist, and a guy with "golden hands" as we used to say. He could fix anything, engines, transmissions, cryogenic expansion engines, vacuum systems, just about anything.

This stuff works like a champ, and I have shared the recipe with the guys at work years ago. Here is how I think it works. The lard has a range of lipids in it of various molecular lengths, the acetone is a small molecule and no surface tension problems that wicks into very small spaces. The acetone carries the lipids with it, and brings lubrication into small spaces. If you have a little gap, you get a short lipid, bigger gap, you get a longer and slipprier lipid. It has saved me on the galvanic type corrosions of steel in aluminum that nothing else seems to penetrate.

By virgin lard, I was joking about the stuff you buy, just plain lard in a can. Not recycled self made lard....i.e. bacon grease. Never tried it though it most likely will work.

I tend to mix it when I need it. The acetone has a propensity to evaporate quickly and I typically throw the residue away. We have a lot of small babyfood jars floating thru the family.

I've thought about using crisco, might be something for you to give a shot at. I guess I wanted to maintain the mystique of my Dad's receipe. Sort of gave me a memory of my best friend everytime I needed his help on another pesky bolt in an impossible area to get to.

Guys give the stuff a try and give a report back. Keep in mind though it is insanely flammable.

I use it as needed for disassembly, then things get cleaned up. I just had this image of your engine smelling like fried bacon! What a hoot. I still use good old permatex high temperature antiseize for reassembly.

BigMoose

edit::to fix some mispellings...I know there's some more in there.

Great info Big Moose, might have to try it. *Note to self* no flames.

 

Thanks to you too Teken!

Man, I am still holding my side re reading your reply. This world needs a few more belly laughs!

My Dad would be proud. He always used to tell me that a lot of the world's conflict could be avoided with a few 's and a couple of jokes. I hope the world notices some day.

Take care, thanks for the roll-on-the-floor.

Regards,
BigMoose

Moose, sounds like your Dad is still alive in your

 

Man I fixed that quick! (Mispelling of Teken)

Tryin' to gin up an explanation.....think......think.....thunk......Uh , dyslexic senior moment! The e is two keys over to the right from the first character on the right of the keyborad, the i two keys over to the left from the first character on the left of the keyboard. Got my nerve impulses reversed to the fingers of both hands....... Happens all the time bwo i mean now.

Repeat after me...Mods Rule.....Good Mods Reign......Teken Rocks!

Thanks Earl. God blessed us richly. Dad and I got to share a lot of life together. Its ups and downs, dreams, successes and failures. We sure shot a lot of "philosophy" together and did numerous projects together. Been 20 years now that he has been "home." Miss him every day. ....... BigMooose sheds a little tear for his Dad......and has in memory. I wish he could have met his grandaughters and I sure wish they could have gotten to know "gramps." He was a better man than I'll ever be......darn...I better stop now, or I'll bore you silly, the fridge will be empty, and I'll be stone drunk...............

to those we all and miss.

BigMoose
