Theres no "supposed to be" it is.

I use grey rtv all the time(at least once a week, often more), I have NEVER had a leak from a joint properly sealed with grey rtv. 3.1 intakes, all kinds of oil pans, thermostat housings, rocker covers...... Again, if GM uses it to seal the oil pan on.....its good ****.

You could also go shopping for a larger o-ring, unless Ive gone retarded this is now like the third time I recommendeed that, and it was actually the first thing I suggested doing.

I dont really know why there continues to be discussions about it. Either way will work, neither one is hard, both are permanent if done properly.

 

Hahaha that is funny you say GM uses it to seal oil pans, what about the leaks on the duramax lower oil pan......yeah that worked for them didn't it

 

I tried using grey rtv to fix a small gas leak on a carb, and what do you know the gasoiline dissolved it into a stickey goo after 45 sec or so and i let it dry for 24 hours first. I do not trust silicone with strong nonpolar solvents like gasoiline, diesel, motor oil etc. Just my two cents.

 

i going to go out on a limb to who ever says the rtv silicone is bad or doesnt work good are not very mechanically incline and/or have never used it properly. my car only has about 600 miles on it i have not noticed this issue yet. Is this supposed to be an issue for every SS? should it be a "recall"? Im not really to conserned i can handle an oil leak myself, unless its the rear-main seal then i wouldnt bother doing it id just take it back ha.

 

I am not intimately familiar with the Duramax, but as far as I have seen/know theres a couple things going on there. A: The Duramax is built by Isuzu, not GM. B: all early Duramaxes used special BLACK Isuzu sealant, I dont know when or if they switched to GM grey.


Firstly, the reason your grey RTV failed in a carb is because ITS NOT DESIGNED FOR GASOLINE. You just dont put normal RTV in a carb. /discussion.

There is NO rtv that you can find at an autparts store that is resistant to gasoline submersion. Thats Fluorsilicone territory.

Since you dont trust RTV for oil, what do you recommend????




And btw....when I say grey rtv, I mean specifically GM Engine Sealant. Also available as very similar products:Honda Hondabond, Hondabond HT(sometimes black), Yamaha Yamabond is also similar, and they are all variations of Threebond 1200 type products.(1209(black) and 1216/1217 specifically I believe) GM used to actually specify Threebond.

 

Oh, I thought grey rtv was oil and gasoline resistant, my bad. I will wait to see what GM does to resolve this issue before I try and fix it myself. I dont want to mess with it and possibly have the dealer try to deny me coverage on another sensor becasue I did something to it. It is still leaking and I sure do not want to have to pay them $120 for that sensor.

 

i agree, i will wait and have the general fix it

 

youre gonna be waiting for a while imo

 

I took mine to the dealer today and I had the mechanic I know replace the sensor. I will check it out again in 5,000 miles, if it is leaking I will have them replace it again.

 

anyone attempt to do the repair by theselves yet with the gray rtv?

 

No, I am just pulling **** outta my ass

 

lol, well hey if it works it works

 

why wouldnt it work? What do the people who have an issue with this repair think the problem is with it? How do you fix it?

 

People just don't know that the person given them info actually KNOWS what he's talking about!

I'm having the dealer RTV it when they install a new sensor.

 

I will run the grey rtv idea by them when I bring it back to the dealer again to see if they will do that for me.

 

This weekend I will be checking out the sensor and if it is leaking i will be doing a RTV fix. As with all the stuff I have done i really do not want to have to deal with the dealer on someing that has an easy fix.

 

Dealer looked at car today, i printed off some of these photos to give them an idea of where the leak was coming from. They said the leak is not coming from the sensor, but somewhere a bit higher up. So im wondering if my dealer is on to something.... or not

 

Yeah they are on something i thought the same thing, but it is coming from the sensor

 

Just had my sensor replaced today and made sure the dealer used RTV

Thanks Maven!

 

my dealer that i needed to get the sensor and a seal.. he said that the seal is not in (after 2 weeks) and no dealer in USA has one. He also told me that the sensor has an o-ring with it.. Now the seal is an actual flange like seal? or is it the o ring already with the sensor.. cuz i want this fixed and im waiting on a part..... so i better need that part cuz im getting impatient.

 

It's an O-ring. Tell them to use Gray RTV, they should have it laying around somewhere.

 

rtv is the ****!! just like jb weld and ducktape true american fix haha

 

Got the leak! I think it looks worse than it actually is....a little oil goes a long way....
I"m not sick about it, but a little irritated. I'll bring it to the dealers attention next month when I get my oil changed.

 

anyone have a real life pic of this?

 

There are three or 4 pics of the the leaking area in this thread just look through the pages until you find them.
