Peanut Butter

What is the part number or name for the grease used on head stud threads that everybody calls peanut butter. I know it's used in the diesel industry. Thanks!!

 

you could try Skippy,Teddy, or detroit diesel international compound number 2
The international number 2 tastes terrible

 

Thanks! I didn't think Skippy would work on the head studs either....

Torquing Compound

--------------------------------------------------------------------------------

Peanut Butter, as it is referred to, is a Detroit Diesel product. It is called International Compound #2, GM part, 1#5198563. This stuff is great for head and main studs, and pushrods. Whatever you do, don't use it on rod bolts, or you'll rue the day!!! Its fairly expensive at about 38.00 per can, but the can ought to last nearly a lifetime, even if you're in your 30's.

IT is now @ $42.00 Dealer

 

What's wrong with oil?

What's so good about "peanut butter"? what's it do that oil doesn't?

 

"Peanut Butter"

It is a special lubricant for use, as stated earlier, on threaded high torque bolts that will improve the tightening capabilties far superior to oil or grease, which will "squeeze" out under high torque pressures..100+ lbs. It looks like and has the consistancy similar to "peanut butter". It is distributed exclusively through Detroit Diesel parts departments, part number and description has already been listed, and is not available from GM Parts.

 

I've known people to use it on pushrod ends. I'd like to see some debate about that. Has anyone had bad experiences with it on pushrod ends?

 

If the peanut butter doesn't block the flow of oil up the pushrod what does it hurt?

Just wondering.... We've never used it on the N/TF's or the Hot Rod's push rods.

Why should it not be used on rod bolts?

 

You should go by what the rod manufacturer says to use. If the bolt is designed to torque to 90 ft. lbs. with oil as a lubricant it will achieve a certain amount of stretch. If you change the lubricant (also changing the friction) to one that has more lubricity then you will change the stretch.

 

Will make no difference if you measure stretch like you should.You are doing the same with head bolts if the manufacturer says torque should be 105lbs with moly & then you use another lube.

 

MKR-588: I agree that the rod bolt stretch should be measured and then the type of lubricant doesn't matter. But in the field in the heat of battle between rounds (especially on fuel cars) there isn't time, so you go by torque. They know that if you torque to say 90 foot pounds with 70 weight motor oil, you will get the proper amount of stretch. Because friction is also part of torquing, using a different lubricant (or none) can skew the stretch at the same torque.

 

do you use the peanut butter on the studs going into the block or just on the top as you tighten the nuts on the head? I assume this stuff is petroleum based, and it wont break down with oil?

 

nuts washers studs on the heads and mains.......never on the rods. Dave

p.s. remember the counter sink on the rod bolt washers face the head of the rod bolt

 

I dont know about using skippy, I think they sweeten it. What about the generic sunshinene brand they give out in the bread lines tastes just like detroit diesel international compound # 2 and it's free?

ps: moly zinc phosphorus assembly lube on the pushrods and valve springs. oil on the rod bolts.
