Any tips for installing LA timing cover seal?

A little rtv on the metal seal shell and whack it with a block of wood & a dead blow hammer.

Once it gets started, and it will take a good swing to get it started.. it will go right in.
If the 1st whack starts it a little crooked..move the block to the high side and tap it straight..then pound it in.
Dont forget to oil the seal before the balancer goes on... and don't tighten the cover down till the balancer is on and bottomed out...use some rtv on the cover seal too...both sides ..sparingly..
Just a skin coat is fine unless the cover is pitted near the water pass throughs.
