I was just replacing my clutch and noticed that i had water leaking from the top welsh plug at the back near the flywheel. Just wondering if it is hard or costly to replace and should i replace both welsh plugs while im at it?
Thanks Ben

replace both for sure.
if you can drill a hole in it and pry it out with a flat head screwdriver or similar.
make sure you use sealant when installing the new ones.

As ^ said, they are only a couple of bucks each. Saves headaches later.

Replace all while you are at it, if one is gone, more than likely they are all on their way out. Having said that, last time I had one, I just replaced the leaking one, on the 308 need to take the whole engine out, as it was a shit to get to, and that was one of the more accessible ones.

i was told by many people not to use sealent(oldn 64 as well)as the welch plug is bigger than the hole,illregular fit?..and sealent causes it to move.so i didnt use any and 18 months later,no probs yet

Personal Prefrance really, They are and interference fit which means they should seal. I doubt that using a sealant would make them move, but I haven't used sealants on them before and have had no probs yet.

Last thing, dont replace with more steel plugs, use brass plugs and forget they even exist!
I use a "very light" smear of make a gasket, to be sure, to be sure!

I am reliably informed a 'non-hardening' sealant is the way to go...Costs about $7.00 for a small bottle. Use brass welch plugs.
This is what I have just done with my EFI engine...

Yeah Chopper permatex is one such brand 
there are others out there too, can't remember the brand on mine and it's too cold to go out to the shed to check it!
It may well be as stated above ^^^^ Loctite 515 rings a bell.

I am not suggesting one has to use but the majority of informed opinions from some of the mechanics I respect suggested to use it
I did ask the question actually as I too was of the opinion it's not necessary. So after asking I took the advice sought and used it and do not expect any leaks either.
I also figured for a paultry $7.00 rrp it was not a big ask!

I had to redo some once.
Who ever had done them before me, was rough and had scratched the plug bore with a screwdriver or something, so they weeped.
Had to do them again *@#$
So since then i always use some sealant just for the security & save the double installation.

Brass Plugs - Used light amount of "Welsh Plug Sealer" funnily enough.
No problems yet.

Use a little bit of "stag" sealant.. yellow tube with a red lid from memory.. the goo is a brownish red colour.. Just a light smear and bash em in!
And yep... Brass ones are best ive found/seen!
