Tard Question..
 

iam iam a tard and dont know how long i should let that form a gasket stuff (atv gasket maker) set b4 i add the fluid?

If it's coolant system work, I never wait at all.

If it's a differential cover, I'd give it an hour, tops.

That stuff sets up pretty quick. The standard way to measure cure time is to leave a sample out on the work bench from the same timeframe as you applied to the truck. Same thickness, etc. When the sample is set up, your question is answered.

its between the transfer case and expansion piece off the tranny

The transfer case did what behind who's barn!?!?? Picture please!

However, I'd give it just long enough to eat lunch or watch a good TV show. Change your oil or something while you wait....

Usually the package will give you good guidelines on cure time.

ok its been sitting for about 30mins i guess i will give it another 30 mins

You didn't put the gaskets in??

yes i put a gasket in between the tranny and expansion piece but 2 dealerships i went to didnt have the one for the t-case do i did that form a gasket stuff for the t-case...

i think bob is implying you shouldnt have used the RTV... just waited on the seal

x2...but im sure it will be fine..and when i do my diffs i tighten up all the bolts in a star pattern then when im done that i fill it..never had a problem ever..sets up quick!

well just put it to the test and it hasnt leaked anything ...i went about 80 on the highway for about 40 miles and not even a trace of fluid...........yay no more leaks.....before the differential, t-case, tranny, gaskets were all leaking and not none are......the guys that were there in savannah can vouch on how bad the leaks were. :biglaugh: :numanuma[ :numanuma[ :numanuma[ :numanuma[ :numanuma[ :numanuma[ :numanuma[ :numanuma[ :numanuma[

haha jsut keep an eye on it for while it should be ok though...good to know there fixed!

not a tard question! I didnt know the answer, now I do

When using RTV, so long as it's the common Permatex type, you can add fluids imediately unless the instructions on the product tell otherwise.
The portion of the sealer that is actually doing the sealing is in between the casting, and most likely will never come in contact with the oil, especially since both halves are machined surfaces.
It takes very little RTV to seal such surfaces, most guys over do it, it only takes enough to fill and voids in between the two surfaces. I've taken things apart where someone has globbed on so much that it never really cures or the edge that's formed come free and gets into the works. This is a real problem on anything with an oil pump or screen. It's not as crucial on something like a rear differential cover.

Myself, I prefer to use an anaerobic sealer like Loctite 518 on any metal to metal situations. There are several brands of this type of sealer. This is closer to what the factory used when new.
Sealers like Loctite 518 are also sometimes referred to as hydraulic sealers, since they work by forming a hydraulic, air tight seal between two machined surfaces. This is also a longer lasting more durable sealer.

Here's a link that better describes when to use each type of sealer:

The only time that there may be a problem with imediately adding oil is on a diesel engine, where as the type of silicone and type of oil and it's additives are also a concern. (Certain types of RTV silicone can effect the antifoaming ability of diesel engine oils).

^ someone did that in my moms truck when she had the t-stat done.
it was blocking the passage way on it and making it overheat.
went to autozone and got a 65cent gasket and didn't use any sealant, been about two years now and no leaks.
