[DML] Re: Manual Transmission Gear Oil

["content22207" <brobertson@xxxxxxxxxxxx>]

I was thoroughly unimpressed with my new bellhousing gasket. Is just a
piece of paper. Did not shed any tears when I had to remove the
bellhousing AGAIN and lost it. Made my own from sheet gasket material
which is not only thicker, but better seals irregularities in the
mating surfaces. Doesn't leak a drop.

Stock PRV gaskets don't hit on much. Valve cover gaskets are pieces of
paper. FelPro makes a much better xRef out of rubber faced metal. I
never could seal my U pipes totally vacuum tight with those paper
gaskets. Made my own from cardboard, and a figure 8 gasket to augment
the O rings, and now could dump a whole can of carb cleaner on them
with no effect.

BTW: I highly recommend changing gear oil while the bellhousing is
off. Makes short order out of what is rumored to be a torturous
procedure. I opted for ordinary 80W90 mineral oil.
