Can't stop thermostat housing leak - 02/12/12 04:16 PM
Is it ok to double up a gasket on the thermostat housing? I have a small drip that can't be stopped and I noticed that the thermostat housing rocks back and forth on the intake and I tried to balance it out some but still not great. If it is ok to double up do I need to use RTV or ultra copper also? Thx

I use the RVT on the housing side. You may want to put a straight edge across the housing to check for flatness.

it's severely warped. Drawfile it (& the flange it sits on) & see if you can get it flat

Contact Moparts member here Gregg Travis AKA Roadhazard for the gasket you need.He makes a few different types for whatever housing you are using.
Got his gaskets on my w.pump housing with a motor plate with zero sealer and ZERO leaks.I also am using a chrome water neck and one of his gaskets dry with zero leaks there as well
Best darn gaskets money can buy

take housing off,buff clean and dry,mask off chrome area,spray with light coat of primer or paint,once dry secure in vise, run flat file across the flange and any high spots on it will have the primer takin off,continue this process until its flat

I use the brown permatex to seal it....Used to apply the Blue RTV ..
As for the rocking...take it off and file it down. It can't be that hard. Go in single motion in one direction. I had to file my one cast iron HP manifold and it took me 10 hours over 2 days to do so. Don't double up the gaskets because the gaskets will probably end up blowing out while you are on the road and then you will wish you had done it the right way. If you gotta get the car somewhere fast, then yeah...double up...but don't leave it accident prone.

[quoteIf it is 1 of those chrome Mopar Performance Chinese specials...
Toss it in the dumpster, you can sand it, grind it, put multiple gaskets and layers of RTV
it will still leak..
x10!!!!
I had one, filed the neck ifself, filed the housing, used right stuff, etc...it never stopped leaking. Total POS.....
I took a chance and tried the billet piece from Source. Never a drop.....
