Stag Wellseal

[jleyton]

I've always used Hylomar, to good effect, whenever I've needed gasket cement however on here last year several people recommended Stag Wellseal, reckoning that it was even better than Hylomar.

I bought some at the time but have only just got round to using it and I've found it awful :shock:It comes out of the tube all runny and so is very difficult to apply neatly - especially when you're trying to apply it to the base of the cylinder block when it's above your head and you're on your back :X

Is it always like this or have I got a dodgy tube?

Cheers

Hi Julian,

The Wellseal i've used was the same, I agree very difficult to apply neatly; however most ofthe joints that I sealed with it have done a couple of thousand miles now and no leaks at all.

The only joint I had a problem with was the sump gasket, but this may have been down to the 'thin' gasket I had. I subsequently used Hylomar for the sump gasket and it's ok now.

cheers

Thanks Dave,

That's very helpful because the sump gasket is the very next job I've got todo . The job I mentionedin my first post was fitting the gasket for the oil strainer pick up and that was hard enough so I really wasn't looking forward to doing the sump with runnyWellseal :shock:

Thanks to your comments it'll be good old Hylomar for me

Cheers

Julian,

Why fight gravity? Apply Wellseal to the sump pan. Stick the gasket to that, then apply a thin film of Wellseal to the gasket. Can do it all the right way up on the bench. You don't need much Wellseal and it goes tacky very quickly.

DaveB has already mentioned the sump gasket. The ones that have been available for some time are too thin. LDpart now stocks some that are close to the OE thickness and much better. I am planning to use one of the OE Unipart ones I picked up at Stoneleigh a few years ago when I do mine.

Hi Dave,

As most British cars 'of a certain age' have a propensity to leave their mark I want to do everything I can to try to prevent any oil leaks and for me that means following instructions to the letter.

You've made a a good point about gravity , however the Wellseal instructions clearly say coat BOTH surfaces and so I'm still going to have to defy gravity and put it on the base of the crankcase :shock:I know Hylomar says the same, but at least it's tacky enough to go on fairly easily above my head.

Do you reckon Wellseal is MUCH better than Hylomar?

It's also interesting to hear what you say about sump gaskets. I got mine from Peter LD - I ALWAYS try him first for everything - about 3 weeks ago but it still looks quite thin. I've just checked it and it's 30 thou but I don't remember what they were like when the cars were new.Do you reckon that's a thick or a thin gasket? It certainly's not like paper.

Cheers

Brilliant, I remember when Carol Cleveland used the 'F' word (I thought it was the very first time in Python?) in her lengthy apology for a previous sketch in 'Live at Drury Lane'

It'd take too long to explain it to those who haven't heard it but if you have, you'll know what I mean and I expectyou'll also think it was brilliant

Hi Julian,I tried wellseal on the inlet manifold to cure a water leak it didnt,went back to silicone that cured it.free tube of wellsealif you want it. John

I haven't used the stuff myself but would putting it in the fridge or freezer make it less prone to dribble on you?

Good idea Baz - just as long as SWMBO doesn't notice

And John, thanks, but I've got one which, if Baz's idea doesn't work, I may be giving away freeas well.

I must admit, I'm very tempted to stick (pun not intended) to Hylomar at the moment.

Cheers

Hi Julian

I had a tube in a plastic container along with a few not used very often tools of no great value,I was searching for something else and noticed the tube had shed its contents in the container covering all the tools in there,the lot went straight into a carrier bag into the dustbin,no way was I going to bother cleaning any of that up.

I have used Wellseal since on my saver shims,which so far have no problems but it's just dawned on me I cant remember where I left that tube.

Funny you should mention this today. At work earlier the background music was particularly inane and I shouted across to my collegue "Shut that @#cking bouzouki player up:P

2 attempts to seal inlet manifold with hylamar with no success ,used well seal and no problem.

When I fitted the EWP I used Stag Wellseal on the Inlet Manifold, stuck the gaskets to the I/Manifold and clamped them up for a few hours, then applied Wellseal to other side of the gaskets and fitted the I/Manifold. No leaks so far.

Good stuff, gets tacky quick. Would recommend.

Wellseal definately works best on joints that dont need big gaps filling, but it does not go off too well, and I prefer hylomar for jobs like sticking cam cover gaskets to the cam covers. For jobs with big gaps (like my cam covers) then silicon is a must, but works best if allowed to go a bit stiff.

For jobs like sumps, if they sit very flat to the block wellseal is great, but I prefer silicon if like a large number of them they are distorted.

One problem with silicon is its habit of forming a string in the inside of the gasket if too much is applied, which can then break off and get places it should not. wellseal just squeezes out and seems to stay in place as a layer of laquer.

Worst case I have come across is a Dolly sprint engine that lost oil pressure due to the half inch of silicon gasket lumps in the bottom of the sump blocking the oil strainer. The previous owner must have used tubes of the damn stuff and it cost me a crank regrind
