Wellseal and stuff

[Claud 14.7 to 1]

Hi,

I split my sump pan off, and after rejoining it with a new gasket it has leaked after only 1 day! I was advised to use some Wellseal (possibly Weldseal) on the join in conjunction with the gasket to ensure it makes a reliable seal. I was told it is quite expensive though (£25), and I'm quite skint so...

Is this product just an instant gasket or it something more special/effective. I noticed 2/3 types of instant gasket at Halfords when I worked there which are considerably cheaper.

Advise me what type to use please. Thank you

It would probably cost less than 25 quid for a new sump gasket. If it was me, I'd make sure that all the mating surfaces are clean and flat (!) and use a new gasket instead of faffing around with sealants.

Cheers

Grim

Surfaces and gasket were as good as I could have possibly made them. I like to do things properly.

It's just doing exactly what I have done before, again, won't guarantee it will hold. As past result has shown...

Or should I pay another 7/8 quid and chance it?

I've had similar problems in the past with rubber gaskets that were not original equipment, material just 'feels' harder. Anyway I think that oil is supposed to cause the seal to expand, this is why I thought o rings and stuff were supposed to be oiled when fitted It might be worth soaking the gasket in oil or at least oiling the mating surface. Not sure what bike it is but personally I wouldn't have a problem using instant gasket with the proper gasket to seal everything on an older bike, only because its not high pressure tho'. Biggest risk is bits of the instant gasket getting into the engine. Just keep an eye on the torque and pattern for tightening the sump back up.

It was a paper gasket, so it will be kept clean/oil free.

Got me Wellseal (£6, not £25) and going to have a go tomorrow when it stops raining.

Very small job that turns out to be double the effort in the end. Typical.

Thanks

Wellseal is really designed to fill small wells in the mating faces of what you are trying to seal, does exactly what it says on the tin. If this doesn't work try just using a decent RTV sealant. I use the out of date ones from work on my own engine builds be it car or bike.

If you get stuck i think i have a couple of tubes that have just gone out of date in my tool box at work. Give us a shout and will hapilly post one out to you. Would normally do about 4 or 5 VW sumps with a tube.
