what is best RTV type & where cam I get it to use on the gaskets during the assembly process of me 22r?

IMO Permatex is the brand to choose. but what gaskets are you going to be using it on? Answering this question should help decide what kind of RTV you need.

oil pan & the corners of the half circles on vc...is there other tyes of rtv that I need to be using during the build?

MOST gaskets do not require added sealant. I only use sealant around diff. covers, a few drops on valve covers to hold the gasket in place (iff I can't get motor oil to do the job), auto trans. pans, and front and rear V8 intake manifold. When properly tightened in correct sequence and torqued to specifications, gasket material alone should provide a good seal. Alot of people experience leaks because they have gobs of sealant around the surfaces and it makes for unlevel mating of the two parts.

For use on diffs and oilpan and a few other areas I reccomend the "Right Stuff" It comes in a very easy to use black can at pretty much all auto parts stores. When using cork gaskets on the oil pan people tend to get leaks from over and under tightning

Toyota Red and Toyota black.

This is the example that was told to me:

"Put Toyota Red on a rear diff, let it set up and you can take the studs out and it will be good to go. Take a big hammer to knock it off."

"What about Toyota black?" I asked

"Take a smaller hammer"

ultra gray by far...MAKE SURE THE GASKET SURFACES ARE CLEAN. WIPE THEM WITH A CLEAN RAG AND BRAKE CLEAN.

I did both within the last month, and for both I used Permatex RTV ultra black high temp silicone.



X2 on getting it really fricken clean, w/o any oil/residue

The half-moon portion of the VC gasket REQUIRE RTV(preferably, but not necessarily, the Toyota FIPG product.) Toyota sez use on oil pan gasket as well.

RTV copper is good for oil pans not alot tho!!!

isn't RTV a 'recreational trail vehicle'?

I picked up some RTV copper for when I do my valve cover gasket.. Should do the trick.

abecedarian

so seriously....
which gaskets are you planning on using room temperature vulcanizing sealants on?
which gasket you are trying to seal makes a big difference on which sealant you should use.

you don't want to use a gasket better suited for coolant exposure on an oil pan gasket, for instance.

but for the valve cover and oil pan, black RTV from permatex will work fine.

I use Permatex Ultra Grey on the rear diff. Though I might check out that toyota red stuff next time I pull apart my 3rd to spool it.


And though I haven't tried it, that Permatex Right Stuff sounds pretty nifty.

Toyota black FIPG. Always.

I can't figure out why there are so many different colours. I understand blue(?) is for coolant, black is for oil, red is for high-heat, but that leaves copper (quite flexible), grey (harder). The all say that they're all good for oil pans etc. Are they all sensor safe? Does anyone have an application guide?

Anyone know the secret Permatex code?

This is the stuff that I used on my diff and we have used on our boat for various things. Good stuff. Took a couple wacks with a hammer to break that thing loose when i had to pull it apart.

edit: alright matt, you beat me too it. But look at the link that I posted. It talks about the different types. I get the stuff through my dad's work, (commercial marine supply store) but you can get it any where.

Little off topic, but this is also really good stuff.

I've used copper, black and grey on the third member. Black held it pretty tight, I had to put the jack under the third to pop it loose. I don't remember what copper was like, and I haven't removed the diff since I went Ultra Grey. You could say that I went black, but came back. None of the three colours have leaked thus far. I don't use a gasket, just RTV.

Alex 400

hahaha, actually from what I remember, I think the last time I took the diff out, I hung from it to break it loose. all 225 pounds of me doing pull ups on the diff. that was with the blue.

Matt16

I can see that going badly wrong if it slipped of the studs lol. I tried that as well actually, didn't break loose. I was doing this in the dark by feel largely so I thought I missed a nut- nope, just 20 square inches of silicone.
