A buddy of mine is a diesel mechanic and he recommended that I switch to Ultra Grey. It seems to work pretty well. He said that is the only one he uses. I have used Ultra Copper and Ultra Black before and they worked pretty good too.

I second the Permatex Ultra Black. As log as both sufaces are clean.

Use what the racers use.... "The Right Stuff"... it comes in grey only and you need a caulking gun for it... its a little more expensive but its the next generation of RTV

I love how it seals and how easy it is to clean up squeeze out... peels right off the next day

I used to use orange a while back. I switched to ultra grey when my friend (who is the service manager at a local chevy dealership and knows more about cars than anyone I have ever known) told me that grey is the only color gm will let the dealerships use. I have never had a problem with it.

Second the Right Stuff. Especially nice for making lifter valley rail seals when installing an intake manifold.

i just tried the right stuff a couple weeks ago. it sealed my rear diff that still leaked after 3 tries with black and grey. stuff is awesome, but expensive(16.00 a tube at napa). for normal stuff i like grey. i save the good stuff only for special occasion.

BTW i recently bought a rebuild motor that had everything sealed up with grey. intake,waterpump, thermostat. probly some other stuff i didnt see as well. no problems at all.

How big is the tube?? I hope its pretty big for $16

I always used the high temp orange. Never had a proublm with it. actuly it worked great. The copper works good to. Never tried the good stuff. I never needed any thing better. I have done intake vallies, valve covers, rear ends, timing covers, exctera.

My personal favorite is Permatex Ultra Black. I've found it to have the best adhesive properties and to be the most forgiving of unclean surfaces. I use it for everything except very high temp applications. For those I would use Permatex Red or Copper.

Yep, this is the best on the market, works very well for problem areas but is too expensive for routine stuff. Its also used by various OEM applications
