Thread: Oil Pan Gasket Maker?

I have one of those same gaskets now. They suck ass! Mine has seeped the slightest amount of oil since install. I used ultra black before, and never a drop leaked out.

use ulta grey rtv with the gasket. I have zero leaks on my new motor. I also used ultra grey with the gasket.

You can look at the specs on the tubes and find out which are better. Basically Ultra Grey resists all the chemicals found in an engine bay, maintains it's flexibility, has a great temp range, and seals under even high clamping load applications. It is everything the black stuff is, but with the added ability to resist squeezing out from the joint under high clamping loads. Check out what the blue stuff does and compare.

Also the grey stuff hides very well versus all the other colors. =D

Master Carr FTW

RTV Silicone Gasket Makers—Replace traditional cork, paper, and rubber gaskets and get high-temperature resistance and leakage control with these pastes. Plus, they create seals that retain torque. Apply directly to metal, plastic, glass, rubber, and wood to form a gasket right in place. Resist most chemicals, solvents, and oils. Fill spaces up to 0.25". Cartridges fit a standard caulk gun.

Blue is a general purpose paste that forms tough yet flexible gaskets. Begins to harden in one hour; reaches full strength in 24 hours. Temperature range is -65° to +400° F. Color is blue.

Ultra-Blue offer excellent adhesion to oily surfaces; contact with oil actually increases flexibility and seal. They're noncorrosive and nonflammable. Begin to harden in two hours; reach full strength in 24 hours. Temperature range is -65° to +400° F. Color is blue.

Hi-Temp Red resist cracking and shrinking from temperature fluctuations. Begin to harden in one hour; reach full strength in 24 hours. Temperature range is -65° to +600° F. Color is red. Meets MIL-A-46106B.

Ultra-Copper Hi-Temp offers excellent oil and temperature resistance and forms highly flexible gaskets. Temperature range is -65° to +600° F. Color is copper.

Right Stuff Aerosol Instant Seal Gasket Maker—In place of rubber, cork, paper, and felt gaskets, these gasket makers create seals that protect against leaks caused by vibration, thermal expansion, and irregular surfaces. Excellent resistance to oils and coolants. Fill spaces up to 0.25". Begin to harden in 5 minutes; reach full strength in 24 hours. Temperature range is -75° to +450° F. Color is black.

It doesn't matter... as long as you clean it correctly and get rid of gasket material and any oil etc before you apply you will be alright. I always clean it with a credit card or something flat and then wipe down with a rag soaked in gas or carb/brake cleaner (something volatile).

Done 3 or 4 upper and lower pans and used the black, grey, red, yadda yadda. All have been fine. I like to use grey and black.

I usually use Ultra Black, as its stated to have the best oil resistance out of all of them. Ive never really had a problem with leaking lower pans as long as both surfaces are clean and dry when you do it, apply a nice bead to the lower pan, let it tack up for about 10-15 minutes and then install and dont put oil in it for 24 hours after install and never had an issue. If you put oil in too soon you will run into problems because it isnt cured.

Another good one is the oem nissan grey rtv, hondabond, and toyotas rtv. All good stuff. I just stick to the permatex as its easily available and cheaper than the oem stuff.

I like the OE Nissan stuff and Honda Bond but the ultra grey and black work as well. The most important thing is to clean all the old stuff off and make sure the mating surfaces are nice and flat. I personally like the orange Nissan stuff but I thought they changed the color for some reason.

Best tip in bold right there. All too often jobs are rushed to get done and although it starts to cure in an hour, you really need to wait longer before exposing it to oil, heat and pressure. This ensures the best possible seal. Same with any water-related fittings that require goo (like thermostat housing etc). I always leave it *at least* over night to cure up and add fluids as the last job possible.

I use the grey purely because it blends in and looks absolutely factory like its never been apart before.

put oil in directly after install with right stuff, seriously. You guys every used it?

Thanks guys! seemingly everyone loves Ultra grey! Ill be giving this a shot,
I got the sr manual for the de-torque pattern!

Ill let everyone know how it is
