Default best way to remove old water pump gasket material

whats the best way? and should i use the blue goop when i install the new gaskets? the time its taken me to get at these leaking gaskets...i DO NOT want them to leak and have to re-do it.


And one other question, the tube with the round shaped canister on the end with the metal mesh in its orifice....I think that is from the air system and should I be doing something with it like cleaning it or replacing while I have all of this stuff out?
















this is from the air system right? should i clean this thing or do something with it while its out?

I use an Xacto knife to take gasket material off.

That thing (I call it the elephant trunk) is the muffler for the A.I.R. pump when it's in divert mode (air not going into the catalytic converter or the exhaust manifolds).

if you're planning on doing any wrenching on your corvette, and you should, go out to your local parts outlet, or go on-line and buy a set of gasket scrapers. they don't cost much, and well worth the investment.

I also use a single sided razor blade with a handle to get the last of the gunk off the block...You can then use some steel wool or very fine sandpaper to buff it up a bit, and get the last of the residue off...Just remember to use a dab of RTV sealent on the bolts because a few of them go into the water jacket and will leak unless RTV is used....To seal the gaskets you can just use any high temp gasket sealing compound made by one of the major companys....WW

Gasket scrapers are the way to go. To help seal the gaskets I use this -

Amazon.com: Permatex 80019 Aviation Form-A-Gasket No. 3 Sealant, 4 oz.: Automotive Amazon.com: Permatex 80019 Aviation Form-A-Gasket No. 3 Sealant, 4 oz.: Automotive

As usual, you guys are awesome. I'll hit it with a blade and steel wool for now and i have some of that gasket sealer. i see there are 2 bolts that are in the water, and i'll goop them up good.

i bought a black 87 2 months ago. then my brother fell for them and together we bought a red 85. we thought we were getting a smoking deal on red 85 because it looked so nice. but underneath i think it has been leaking from 6 spots (2 tranny, 2 oil, 2 coolant) for the past 25 years and nobody has done anything about it. So we are doing it right.

But WOW what is with people not taking care of these cars on the basic maintenance side of things. They are gorgeous cars that perform incredibly and cost almost nothing....i don't get it.

Anyway, thanks all and i'll be posting again if I encounter some trouble while replacing the tranny dipstick tube seal and the tailshaft seal.
