Gasket Sealant

This week I'm swapping out steering gear housings. The previous owner mounded JB Weld over the crack and the radiator was force fit over that. Even with all the RTV they used it has leaked like a sieve.

With the new steering gear housing and radiator should I use gasket sealant with the cork gasket or is the cork gasket enough?
 
keep in mind the bottom plate of the radiator is soldered to the tubes if it was forced out of shape it needs to be formed to the "new" casting and then resoldered.
no amount of RTV will seal it when the soldered joints have been broken

The old radiator definitely has cracks where the tubes meet the plate. I decided to go with a new radiator as well. I don't want to deal with any more leaks!

I'll go with the with a thin layer of blue RTV on the gasket.

By the way, I appreciate all the advice for all the questions I've sent in. I'm new to tractors and I'm diving right in with this restoration. I've also read more posts than I can count--this forum is a wealth of information. Many thanks to all.
 
I used the spray on Permatex gasket sealer and have not had any leaks on the radiator gasket.

Now I know this going to sound a little strange to some but this has worked well for me several times. I use a small wax string held in place with a little weather strip adhesive in place of a paper gasket. I learned this in A&P school as the recip. engine halves are sealed with nothing more than a silk string. Wonder if anyone else has used this technic before?
 
WKPoor,

We used that method when rebuilding steam turbines at work. When going back together with the turbine lid, we put a thin coat of Turboseal on the base and put a string out of a larger piece of rope packing in the turboseal and set the lid on and bolted it down, No leaks.

Yep, when working on old Corvair sixes or Volkwagen aircooled 4 s that had a tendency to leak. They used no gasket at all between the crankcase halves normally and just relied on precise fit to prevent leaks. Our fix for chronic seepers was to use a piece o monofilament fishing line, very small, about 4 lb test between the halves. I have used this trick, with bigger monofilament between two cast parts when no gasket was available.

We've used monofilament fishing line between the case halves when assembling.
