Liquid gasket

I have used a ball-bearing larger than the hole. Gasket paper trimmed to
shape and placed in posoition over hole. Then press down the bb over the
gasket/hole to make a slight indentation so the the bb stays put. Tap bb
with a hammer and voila - perfect hole in gasket (or "hanging chad" - easily
removable). NB "tap" is important as wellying the bb could have unfortunate
results!

 

FFS.

.... or, instead of all that fucking about with gasket paper, scanners,
printers, grease, X-acto knives, cornflake packets, safety scissors,
slightly-oversized bolts, ball-bearings, mallets, chad, and all the
other crap that's been mentioned, I could just use something that's
designed for the job, and comes in its own conveniently-sized dispenser
that probably contains enough goo for at least ten such gaskets.

Sheesh, I didn't think such a commonly-used technique would be so
controversial. It's not like we're even in ukrm.classics, is it?

 

And it'll just piss oil everywhere afterwards. Trust me, it's easier to
make a new gasket. The gasket paper can be bought at any decent
old-style motor factors shop locally. I got some within half a mile of
my gaff for about a quid a sheet.

Yet they couldn't machine the bores to the pistons so they didn't burn
a litre of oil every thousand miles.

 

Werll, bit of a moot point there. *Mine* didn't burn any oil. There were
plenty the same. OTOH there were, as you rightly point out many that
*did*. Not sure that it was soley due to bore <> piston though. Do you
have any 'reliable' sources, IYKWIM.

I'm not sure what your follow up has to do with my original post. I
wondered how a design that originally used a paper gasket could
suddenly do without it, without any other changes.

And anyway, crankcase halves are different. Usually they have to be
bolted together securely enough to keep crank and gearbox in position,
so gasket paper can't be used anyway. All the inline jap four engines
I've worked on have crankcase halves that don't use a paper gasket,
and (IIRC) don't even use liquid gasket everywhere.

 

I just had to top up the R36 engine tonight, as it was flashing a
warning light. Took about 3/4 of a litre to get back to the full mark.

That's the second time I've had to top it up since I've had it,
totalling about 2 litres. And it's only done 25000km, FFS! Bloody VWs,
eh?

If the original fit was a paper gasket they are very easy to make.
Get a sheet of gasket paper from any decent car spares shop and tap
out a new gasket with a small hammer around the edges of the cover.

 

I like that idea. Not the exploding ball bearing, but the ball would cut
very "smoothly".

Of course you could and you could also discover that a little too much of
said goo will dribble not only on the outside, but also on the inside of the
cover and then migrate into the smallest of oil galleries and block the
fuckers up. Of course if you use exactly the right amount, it's not *too*
likely, but what exactly is the right amount? Anyway, your response does
make one wonder why the **** you asked about liquid gasket in the first
place as you're obviously an expert on the subject.

You lose.
I already gave the non-bodgers option.
Please credit me with some mechanical sympathy and leave the pikey
solutions to the usual suspects.

 

Ten hours after everyone else.

 

.... also useful for dentures.

.... for that increased "stuck to the road" sensation.

Ewwww. I think somebody got a bit too excited.

 

I just use a set of old fashioned leather hollow punches similar to

Neat hole every time.

Oh, and use the ball pein end of your hammer to go around the edges,
makes it a lot easier.

P.

 

In fact, the earliest 900SS parts catalogue at ducati.com quite clearly
shows fluid sealant, no gasket:
http://www.ducati.com/en/bikes/service/parts/2000/pdf/SS900ie_Eu-00.zip

Page 50: Alternator cover; no gasket to be seen, item 15 is "Fluid sealant".

 

Well, that's the kind of information I was after, really.

As you've correctly stated, I asked about *liquid* *gasket*. Most of the
responses seemed to be answering a different question, one that I don't
recall asking.

 

Nice cast, lovely presentation ....

But the quarry glides away ....

A thin smear applied with a finger then left for a few minutes to
partially set before assembly.

 

Some sources - no idea how reliable they are, though - suggest that the
oil consumption is due to the rings/bores taking a long time to bed in.
