What are welsh plugs worth? And are they hard to change? My mechanic reckons that some need replacing but I am not sure exactly what they look like but I am guessing that as there are 6 on each side that I look for 6 things that look the same on each side of the block?

I really hope the one under the bellhousing is okay..

Round concave plugs about 3.5 cm diameter. Pull out with a slide hammer, hammer in with an old socket that will fit inside them and use sealant before installing.

Mum just told me that the mechanic said $98 for a set and about 1.5 hours labour - does this sound right? I am assuming a set means 12 - not the one under the bellhousing..

The "welch" (or frost) plugs are to fill the holes that are necessary to facilitate casting the block. They supposedly pop out when the pressure in the block rises due to the freezing of the water in the block (antifreeze/coolant prevents this anyway unless you live at Scott Base) to prevent cracking it.

To warrant replacing them they should be leaking. This should be obvious if it's happening. I wouldn't bother doing any that aren't leaking - cos if they aren't leaking before replacing them you can be sure they will be after.

$98 sounds expensive for just the plugs - they're just pressed disc's. If I were you I'd shop around & buy and install them myself - it's not rocket science - just keep an eye on them & the coolant levels for a month afterwards & you'll be fine.

Each welsh plug should be around $4-$8. I guess you mechanic hasnt quoted you for the one at the back of the motor, coz I can assure you...it would be more than $98. Most mechanics charge about $35-$50 an hour, so that price is about right including the plugs and sealant (Stag).

yeah thanks guys for the info.. i might get a second opinion from a mechanic friend b4 i go off and get it done.. just that I am about to change coolant and from what i gather the coolant will come out when i remove the plugs and i don't want to do it twice..

I can see some liquid around one - the one under the inlet manifold but i am yet to check the exhaust manifold one..

Go buy a set yourself..then see what the labour is to fit them. Thats the best way. Even if you dont have to replace them all you have a full set for later on down the track.

Welsh plug sets can be bought for around $25, or roughly $4 each, be sure to buy brass or stainless. Do it yourself, its a bitch to get to but it saves a bit of money

I did mine a while ago
