Gel seal application

[ct1762@gmail.com]

A tad confused as to the proper technique to applying gel seal on the crankcase halves. Looks like i've been possibly doing it wrong all these year according to a 1982 manual i've come across as below. It's showing just dabbing the gel seal on each flange, and not all around the block. Doesn't make sense to me,as wouldn't it shim the halves apart and leak at the ends this way? I've always done a thin bead all around, and never had an issue. Also says to "oil labyrinth seals on block and case halves to prevent lockup from excess gel seal 2", which i never did either. Any thoughts on the correct way?

What manual is that from ??----And no , ---If you use the factory specified " gel seal " you do not have to worry about shimming at all.------The stuff has no fillers and 98 % of it squeezes out with the result being a metal to metal joint !-----I use a 1/8" diameter bead all around and never a problem.

So no sealant as shown at the tapered ends? That's from a 1982 OMC factory service manual. don't have a newer manual to compare, but fairly certain the newer manuals say to put a continuous 1/8" bead all 'round, even on tapered ends.

I have been doing this since about 1970 or so.----Use the correct sealer that does not have fillers.----Use a current manual.
