    Default Permatex gasket maker- who uses what and where on engine assembly?

    There are 9 kinds of Permatex gasket maker on my autoparts shelf. After reading their website it appears they all are for "Valve covers, oil pans, timing covers, water pumps, transmission pans".

    There is some range in temperature difference between some of them.

    They all say they oil resistant, the only one that seem logical are the ultra copper for exhaust and the water pump T-stat RTV which is the "highest water-glycol resistance available in an RTV silicone"

    So why not pick the one with the highest temperature rating and be done with it except with the glycol applications.

    Since I am not a big fan of seeing blue RTV on motors i guess I will use the black for most of my engine assembly.

    Here they are from the Permatex website:

    Default This is an easy one...

    With the exception of high-temp applications (such as catalytic converters), the only sealer you will need is Loctite's 5900, aka The Right Stuff sold at Napa. Don't get the cheese-wiz cans, get the 6oz caulk gun tubes.

    After using sealers for 20+ years as a 'professional' auto tech, this stuff is by far better than anything else out there. I wish they had it back in the days of cork vc gaskets on SBC's, Fords and Olds. Would have saved a lot of comebacks.

    Yep. The Right Stuff is in fact the right stuff. I've used lots of times and it works great. A couple times I didn't have time to go find an oil pan gasket, so I just used Right Stuff. Works great.

    The only exception for is the intake manifold. Just an old habit I guess, but I use clear GE Silicone for the end seals, and a TINY bit around the water ports when installing an intake manifold. I've never had a problem with leaks doing it that way. But, thinking about it, the Right Stuff would probably be better there, too.

    Have fun.

    I'm a little more old school. permatex black silicone around the water jackets and the corners of the intake (intake, block and head gap) along with the rubber gasket. I then use Permatex Aircraft sealer espically for the paper gaskets. it's a black-brown gunk that sticks and seals really well but is a PITA to remove. You'll tear the gasket before you un stick it from the mating surfaces.

    Would you use Permetex Ultra Copper Gasket Maker with a Gasket on a water pump?

    The Right Stuff everywhere except where there is gasoline.

    Best product out there.
