Liquid Gasket - use or not?
What's the census of opinion on using liquid gasket on gaskets?
I'm putting my 2lt pinto back together and don't know what's best, when I took it apart the guy who had it before me had used it on
nearly all gaskets.
I thought it should not be needed if using a reputable gasket set.
what's everyone's thoughts?
Alan.

Peter Wallage (who writes the Pinto/Xflow books) suggests that you only need gasket stuff for the rocker cover - so that the gasket stays attached
when you remove it for maintenance (it's just to glue the gasket to the cover)

I used liquid gasket for my sump instead of the usual cork gasket. Got a tube of it from halfords and it says its a replacement for cork gaskets. It
seemed to squash nicely into all the gaps and i haven't had any trouble so far, although bear in mind i've only covered a total of 20
miles...

Hmmn...
I hate the stuff yet still use it.
I suppose it's a case of use it where required -- my Mitsu uses it from the factory in place of an oil-pan gasket, seems to work OK.
Doesn't matter what I use on the Minis though, they flippin leak anyways  .
If you're going to use it as a belts and braces type deal with a proper gasket I would try two different sealants, weather-strip adhesive to
glue gasket to the part and a thin smear of quality automotive silicone on the block side (for water pumps or other accessory gubbins -- never
anything on a head gasket).
Weather-strip adhesive holds the gasket securely in place on the part (dries quickly) so your gasket doesn't shift about while feeding bolts
through.
When it comes time to do the job again the silicone pulls away easily.
Cheers, Ted

The kawasaki engine im rebuilding at the moment uses a lot of gaskets.
However, the main crankcase seal - which is horizonal across the cases - doesnt use a gasket - it uses summat called 'kawasaki bond' -
which im taking to mean instant gasket......
lots of area to seal........ inc keeping the pressure differential beween crankcase chambers.....

Instant Gasket
Never use RTV on the engine side of the oil filter. It squeezes out and will block an oil way in the crank.
I like Loctite 518, not cheap but a tube will last years and it will not go off. I often put a thin smear on gaskets, belt and braces approach as I
tend to worry a lot.

ive used blue hylomar before. it seals but never actually sets hard like silicon or red hermatite - so its easy to get off if needed later
