Re: Crankcase - block gaskets

Charles,

my point is that someone has to try it first - you are obviously tempted so why not just go for it?

Can I also ask, if the Loctite works for you, why are you looking to try something else?



Re: Crankcase - block gaskets

What I have done on the Bantam (most definitely not a racing engine) is
1. Stick a sheet of a fairly heavy grade of gasket material to the crankcase,using the block to hold it down. First punch holes for the studs of course.
2. Trim around the block with a craft knife, then lift the block off.
3. Trim around piston holes etc
4. Trim back the gasket sheet by about 5mm all around the perimeter.
5. Apply a thin bead of appropriate grade silicone all around the perimeter.
6. Replace the block and loosely fit the nuts, then wait for the silicone to cure.
7. Tighten the nuts. (I usually wait several days before doing this).

That's how I skin the proverbial cat. It works fine and practically no cost. The tin baffles would complicate things of course but Bantam doesn't have them, fortunately.

First mover disadvantage puts me off, especially with the thoughts about creep.
However I'm always looking for better ways, hence my curiousity. I'd just prefer not to remove the block again. It's bloody awkward with the blower!

Re: Crankcase - block gaskets

If it helps persuade you to try Charles, my Nippy runs the correct engine together with 9E77 cam etc, so the loads are probably fairly high, certainly far greater than your usual road engine...... I also have a rather heavy right foot
I will be experimenting with one of these gaskets in my special once I finally get the thing back together again, however I have been rather dragging my heels on this front recently.
