Broken easy out - nightmare scenario

[mpats]

I have to say I never use copperslip. Either neverseeze, it's fantastic and is fine in dissimilar metals or mastinox or equivalent. Although in a lot of applications neverseeze is the almost unbeatable.

Copper grease coats the material with a soft metal, namely copper.

The finely divided copper remains in suspension, it doesn't bond to the substrate to which it's applied. There is a distinct difference between that and an electrolytic or chemically bound "coating".

The grease should be of a reasonably high temperature resistant type too, so shouldn't break down, or be removed if used properly.

If the grease is removed completely, the remaining copper could cause the part to seize by generating unnecessary friction, akin to dust or muck in a joint.

Another happy user of copper grease here, can't recall not being able to undo anything later. Including glow plugs.

seams copper grease is getting thinner though in my experience and does not last as long unless I need to try a different brand, my new tub just isn't as thick and copper rich as the old 10 year old tub

Because it has not yet had ten years for the volatile parts to escape leaving behind the thicker fraction?

I guess that is quite possible I didn't think of that

Think both SO & Facom do them, we use them for screws that have damaged heads especially where people have butchered Phillips with posi bits, the The nut plates usually have tight deformed thread (not seized)

I can - I once used it on little brass idle mixture adjusters on a bank of motorcycle carbs. 2 weeks later they were seized solid.

which ones do u use for damaged screw heads?

Where did I say it bonded to it, I said it coats it.

Mee, I wasn't aiming my post at you personally, but there are caveats to using copper grease I was trying to affirm to others reading the thread.

Others have had success, others failure, there's a grey area that would appear to be causing issues and I was trying to clarify a possible cause. That is, if the grease component is eliminated, or driven from the joint by heat/pressure, leaving the remaining copper behind it could cause more issues that help...

Having something copper "coated" in my mind/learning, implies an electrolytic/plated coating with respect to copper, this could be even worse as there would be an electric potential between the copper and the substrate, and/or the opposite face of the joint, accelerating corrosion of either the substrate or copper at the joint...

Found that, ive stopped using it on spark plugs as the build up started to interfere with the new plug going in , just use a wipe of engine oil now. Still use copper grease on every other bolt and screw as well as supplementing exhaust gaskets and a smear on cylinder head joints. Our cars don't use gaskets here the barrel just sits in a rebate in the soft ally head.

had this with comma copperease. got a new tube of granville seems pretty good

Thank you for the clarification.

I've come to the end of my one and only can of Never-Seez, after 30 years of v.sparing use. It's been fantastic, but the price of it here is fantastic, too.
Reluctantly using Copaslip equivalent for now, but I'm on the lookout for bargain NOS Never-Seez from ebay.com. I've seen a few, but the shipping has been insane. Occasionally, a seller is clued up enough to send it cheaply.

I run an iveco if mine go i will pm you well done

Stopped using Copper grease on a lot of stuff, ever since I aquired a tin of Anti-galvanic paste. It doesnt dry out like copper.

BIL gave me a set of Sykes Pickavant splined easyouts, very handy bits of kit, and so are TORX bits.


I did watch a ut video, where they used a chemical to remove a broken stud in a ally head, but I cant remember what it was

Probably alum.

Probably alum.

Maybe, it needs heating to work though doesnt it?
