Copper anti-seize on injector threads? 1.6na

[arb]

I don't think the threads of the injectors or glow plugs would ever see 350°F.  Zinc is good for more than double that temp.

Exactly my point too ;-)

Thanks to all, this is great info!

I hope you enjoy the group even half as much as I do - always learning something new from these guys :-)  I thought I really knew these engines inside and out, and every day my % drops even further with aspects I did not know exhisted. I'm down to maybe the low teens now...

[Smokey Eddy]

Even through my saddest days i get out the camera to show you guys pictures of my mistakes jutting through the side of the block so you may learn at my expense =D

Everyone learns when a poor unfortunate soul goes wrong somewhere. But hey. If no one went wrong and posted about it.. others could follow the same path.

SALUTE to Smokey Eddy !

[morgoon]

Yes a Salute! indeed I have been following the Carnage thread

Gulp!

What if we all sent Smokey Eddy a bit of JB weld

Perhaps we could get him back on the road

Turn the Carnage thread into how far can you drive on JB weld thread

Thanks for the warm "weldcome" from an obviously bored newb

aw gee thanks guys. just so this thread isn't TOTALLY jacked im going to flat out say

Yes, anti-sieze the injector threads. Helps seal them too. (don't forget to reduce the torque value though. anti-sieze is grease with alluminum powder in it. reduce the dry torque value by 10% - someone correct me if im wrong please)

at least i'll have a full on 1.9aaz build underway. But i am kind of sad to see the 1.6 go. I liked having something different.

Yes, anti-sieze the injector threads. Helps seal them too.

The heat shield is all the sealing it needs provided it gets torqued right.

Mor, "gasoline only" when a Tech checks an engine for compression and finds a low Cyl, they want to know if it is valve train/head, or rings, the old school way is to add oil to the questionable Cyl. If the rings are bad, the oil will bring the compression up, this lets the Tech make a complete diagnosis for an estimate of repairs. The high tech way is to use a leakdown tester and all of the neat stuff that goes with it. So no oil in Diesel Cyls for compression check please, if you have low compression, tear the engine down.

Also, please take note of what libby said, the question is not heat but Galvanic corrosion, Zinc based is better, and make sure you torque the injectors, (you do have a good torque wrench ), and replace the injector seals, and make sure you put them in facing the right direction, heat is not a concern, leaking combustion and Galvanic corrosion are.

Thanks for the reply

I am in the process of building a leak down tester from some parts I have laying around

But I am out of the VW game tomorrow, disapointing, as I had a day off planned to wrench away, but I have just gotten word that I have a bunch of  work to get caught up on for a deadline tomorrow



Thanks for the heads up....

but who here has never had a leak from the threads before? honestly

oh sorry im talking about using anti-sieze on the mating parts of the injectors them selves. never miinnddd

[morgoon]

I went with copper, I think that was where the thread had last left off

Then when I got back to it...we had moved to Zinc

I did not get any real "WWWWWWAIT" don't use copper replies..

It is all good... I think

[ToddA1]

Off topic, but you were using gas as a penetrating oil?  Never heard that before.....  I recently used ATF and acetone with great results.

So put them in clean and dry, or PTFE tape.

i think andrew already mentioned the galvanic corrosion? or some sort of chemical reaction between the copper and aluminum? i have always been told to use something BESIDES copper anti-seize on aluminum, or anywhere that a part will come in contact with aluminum. ive never personally seen a case of copper anti seize eating aluminum, but ive never questioned it either.
