Core plugs - What do you recommend?

Hi all,
Replacing the core plugs on a 318.
When replacing the core plugs do you put sealant on the outer edge?
If so what do you use?
Many thanks,
Steve

First,always use brass plugs and don't forget the ones at the rear. I seal with either Wellseal, Shellac or clear silicone. Make sure the hole in the block is very clean and there are no burrs on the plug. Find a drift that fits the size of the edge of the plug and drive in perfectly square.

Ace, thanks guys - I have some brass plugs ready and I understand there are two at the rear.
Wellseal is not something I have used before - better than standard silicone/instant gasket?
Im no engineer… but when was it ever a good idea to use a metal that corrodes, money I guess!
Thanks again,
Steve

Wellseal is available at real motor factors,not Halfords. It is cleaned off using methylated spirit,much like shellac,it really probably is some form of shellac with a fancy name. My view is that it's much better than silicone as being alcohol based makes it nearly everything resistant!
http://www.wellseal.co.uk/ You can buy direct and likely £3 cheaper than factors.

Although I'm not really a fan of that particular organisation.

Sure they'll be fine sending out a packet of core plugs
Bit of 'history' between us involving a dispute a few years ago, never used them since.

Thanks, I've got a slight leak on one but wanted to change as many as possible, I suppose to change them all it's an engine out job ? Shaun

Use brass, like everyone sez.
You can do them in situ with some components stripped down. I've seen John S and Birdman Chris replace the most difficult one behind the engine mount at the track. In fact I helped the boys do one at Shakey last year.
