What RVT?

I use ultra copper on everything. But I changed the water pump in my Bronco with regular blue and never had a leak. Just remember to be patient with that stuff. What I found to work really well is to torque your bolts at 20-30 in-lbs or so, wait a day then torque it all the way down. That way it doesn't just all ooze out before it cures! I still have no clue what the difference is between Black, Grey, Blue, Red, Copper RTV :shrug: I was actually going to post that question.
 
I used a wire brush to remove the gasket material from my heads when I did the intake swap. I put rags in each port of the head before using the brush, then just pulled the rags out with any debris laying on top of the rags. Then like Chris said, you can use a vacuum and suck the debris out of the lifter valley. Just make sure you don't use something that you won't be able to get back out of the port, I've seen a picture of someone who had paper towel plugged in their valves, it wasn't pretty. Good luck.

If you go to the Permatex website, they have a PDF catalog of all of their automotive products that has an application chart inside.

Basically it's a heat range vs. ductility thing. The copper is supposed to be good for everthing except intake end seals (not ductile enough would be my guess). Black is good for most things except thermostat housings, water pump cover gaskets, and exhaust manifolds. Blue is almost the same as the black, but not reccommended for intake end seals.

The Grey is for everything import :shrug: except exhaust manifolds. . .

damn... i used the black (very lightly) because i didnt want to drive to the parts store to pick up another t-stat housing gasket...

its been trouble free now for almost a year :shrug: if i have any problems ill buy a $2 gasket
 
So,when i swap my intake i am only going to use RTV on the lower gaskets and the t-stat housing gasket?I dont use any on the upper intake,and the throttle body gaskets.Just asking to make sure.This is my first time dealing with gaskets.

thanks

First off, I'm not trying to be a prude but its "RTV", not "RVT". Just wanted to save you from some embarassment or confusion down the road. Second, I put a dab of the black high-temp RTV in the corners of the lower intake gasket and a bead of it on the front and back of the lifter valley. Don't use the cork gaskets that some kits include, just use a nice bead of RTV from one gasket to the other across the valley. :nice:
