MG TD TF 1500 - Use of gasket dressing for SU's

When re-installing the SU's on my TD, should I use any gasket dressing on the gaskets for carb to intake manifold? Carb to air cleaner manifold? If so, what is recommended?

Thanks in advance. Mike

Mike,

If the mating surfaces are true and flat I have never used any sealant. Later disassembly is easier with no cleaning required if you do not gum-up the surfaces.

If the mating surfaces are true to each other, I don't use any type of a dressing and only use new gaskets and never re use old ones. If any dressing is needed, I spray the gaskets with High Tack, let them dry to a tacky surface before setting them in place. If the mating surfaces are not true, I hone them on plate glass and fine carborundum paper until the high spots disappear. Needless to say, I don't like using gasket sealers if not needed, but that's just me. PJ

The carb flanges are often slightly bowed and surfaces often beaten up. I always use either a very thin film of blue Permatex or Permatex aviation sealant between the carb and intake manifold gaskets. Leaks are very common there, even if perfect faces I would still use a sparing amount. Carb to air cleaner not so crucial. George

Agree with George...easy enough to separate later but strong enough bond to eliminate leaks now.

Thank you for your replies. I will plan to use a very small amount on the gaskets between the carb and intake manifold. Appreciate the comments.
