Wellseal Instructions

[spookefoote1956]

Hello again. I've ordered some of that Wellseal goo having heard good reports about it. Some websites suggest applying some to both surfaces and leaving it five minutes, some overnight. What do any of you suggest?

Cheers, Chris

This what I do, it my not be right but it's what I do, say for example the timing chest...............apply wellseal only to engine side face, place gasket in position on the wellseal and then place cover on and tighten screws, my theory is if you need to remove the cover at some point it comes away easily and leaves the gasket on the engine.

If there is no gasket I apply well seal to both sides and tighten straight away then clean dribbles with petrol.

I also recommend buying a tin of it not a tube, it's much cheaper as it's shelf life is very good, (it doesn't go hard)

Only my opinion.

Hi Spooky

Wellseal is brilliant. I use it on both sides of the gasket and then hang it up on a length of wire, and then on both mating surfaces. I leave it for at least 10 minutes before assembly - on vital joints such as head gaskets I leave it overnight. It never goes off and gaskets normally stay in one piece on disassembly.
A pot is much better than a tube and it will probably last a lifetime. Apply it very sparingly with an artists brush and clean off any which squidges out with thinners.

+1 for what Jim says. Ive used nothing else for years and my bikes dont leak oil. Buying a tin is much cheaper which also appeals up here in Yorkshire

Hi

Similar to the above, the only jointing compound I use nowadays.

I find it easier to apply to the case with it horizontal on the bench, add the gasket and apply a second layer of sealer - assemble after around 10 minutes.

I use the wooden coffee stirrers available for free on any high street for spreading the compound.

Didn't realise it was available in 500ml tins just bought a tube to replace my first one which I've been using for several years now.

Head gasket? Tough stuff!

Hi Dave

The recommended tried and tested way to get a Sunbeam S7DL head gasket to seal, solid copper or composite - and it works!

Wellseal for me too, excellent stuff. Recommended by VW back in the day for assembling their Air-cooled engines crankcases which are joined vertically with no gasket. I used this when I rebuilt my beetle engine back in the early eighties and have used it since. More recently(two years back) I used it on my Yamaha RD350 engine rebuild and no leaks

i just use some cheap artist brushes to apply it , a few bits of scrap plywood to lay gaskets on to coat them with etc .

one thing i would mention is that the tube of welseal will have a tendency to dribble out the end if you leave it laying about with the cap off or have squeezed it a bit and compressed the tube , or when you have gripped the tube and then took cap off, especially when its hotter weather .
