I have used Permatex Ultra Black on a number of occasions and have had good
luck. Disassembly of items cemented together with this product can be
challenging, though. Maybe I should try the "ultra-gray". I find things work
best if you can insert a couple of studs into the larger half of whatever is
being assembled so that the attached item goes on straight, without any
sideways movement. I have found that large gaskets for tractor transmission
castings have gotten really expensive ($50 plus) and then sometimes they either
come damaged from shipping, crack & break when being installed, or holes don't
line up properly for bolts. As a result, I tend to use the "gasket-in-a-tube"
approach more than ever. Sometimes I find it challenging to decide what product
to buy - there are so many.

Subject: [TR] Gasket sealant for sump
Iâ??m resealing the engine and transmission on my TR4 after 20 years of
reliable service.
Today I had a massive failure installing the sump gasket using Hylotyte Red100
sealant. It seems to have weakened the gasket to the point that it tore around
several bolt holes as I torqued the bolts.
Plan B is to thoroughly clean the mating surfaces and use Permatex Ultra Gray,
which Iâ??ve generally had good luck with on my Alfa Romeos.
Before I do that, I wanted to see if any of you can recommend other sealants
for this purpose. I only want to do it one more time.
Thanks.
