MG TD TF 1500 - Hylomar

Should I use Hylomar blue sealant or any other sealant on the valve cover gasket and or rocker cover gasket. Or original cork without any sealant will be good enough.

Way back when I used the cork gasket. I sealed it to the head with ASutomotive weatherstripping adheasive,,It stayed in place, and took a little longer to leak,,,,, Then I switched to the Silicon Rubber gasket,,, Many miles and many cover r&r's and still no leaks!! MUCH better than cork,,,
contact Tom lange and get one!!!

Boris if you stay with cork use a permatex product to "cement"it to the head and hylomar is fine for the rocker cover to gasket side. There will be many more good suggestions I am sure.
I went with Tom lange's gasket myself. No leaks. Regards, Tom

My mechanic suggested I not use any sealant just make sure the valve cover is tightened down well. Some time I plan on buying Tom's silicone cover though...

I'm not an expert, but I don't use any sealant on valve cover cork gaskets on my TF or my '54 Chevy truck. Nothing more than a slight oil ooze under either valve cover. Easy to remove the valve cover to adjust valves.

I used Permatex Super "300" Form-a-Gasket Sealant on both sides of the push rod cover cork gasket on the side of the truck engine. It's non-hardening. No leaks.

Gasket sealer against the valve cover, grease against the head. No leaks, looks nice, and comes apart easily.
