Gasket sealant instead of 'real' gaskets

So this could be divisive, but I simply can't get a correct gasket set for our old Perkins HT6354's. I've been through three sets already and none include the correct gaskets and I have admitted defeat. Our engines are reasonably early, and have an elongated main sump that I can't seem to find through anyone (DiPerk, Parts4Engines etc). I now want to get he running so we can enjoy the summer... when it comes!

So my choices are to make them from fibre gasket material, which I don't really have experience of doing except for small paper ones on my old Vedette, or using some (good quality, proper) gasket compound designed to replace gaskets. I know that this is used now on Mini, VW and lots of new cars, but I wonder if anyone has used it before to do a proper job on a boat before. This is for a sump, not under pressure really and in good condition.

Thanks!
 
For gasket material, locate your nearest 'Classic Bike' type motorcycle dealer
Plus they will have different types of 'Hylomar' sealant
I loacated a gasket set for your engine from the local Farmers tractor/ engineering place
It was about 8 years ago though
They were John Deer agaents but had loads of parts books and spares from when they dealt with Perkins prior
Lots of those motors still in use with 'enthusiasts' etc
 
Three bond 1215 is very good, Ducati use it as OE sealant as they don't use gaskets to join the crankcase halves or engine side casings. I've been using it for years and highly recommend it.

As regards gaskets we used to make our own most of the time when I was an engineer with BP, tools used were a ball pein hammer and hole punches......steam gaskets were fun as they were wire reinforced... The word Klinger still sends shivers through me....

I think if the joint was designed to have a gasket then it needs a gasket.

A joint designed and manufactured at a very different time may not need a gasket and be able to rely on some sealant, but that doesn't mean a joint designed for a gasket can be made oil tight without.

If I was you I'd be spending an evening at the kitchen table with gasket paper, scissors, sharp stanley knife, steel rule and some hole punches.

Not sure if I mentioned this on a previous thread, but when I gave up with 6.354's I had some manifolds and coolers left over, I sold them to a David Harrison, he was the Broom club tech support guy, might be worth trying to reach out to him.
