Welsh Plugs??

Okay here we go. Time has come for me to rip apart this old 173 I have in the back room and see whats what. Have come across three circular brass looking inserts in the head. I am assuming these are the welsh plugs. Two were starting to rust out so I dug out the centres. Are these plugs something I can pick up readily or will I have to get them ordered to match the engine? Also does anyone have a good remedy for getting the rims of the plugs out?

Simmo.

Yeah mate very easy to get I work for repco and we carry heaps of them. I did the ones not to long ago on my 202 (a real pain after being there for 33 years). I found the best way was to use a cold chisel, hammer and a good long screwdriver. Bash through the center then get the chisel (nice n sharp) n try hitting the rim to loosen it once its loose and moved inwards a bit try getting the screwdriver and levering it on the rim and push against the head to get it out. This worked for the ones in the block mabey use the chisel to lever the ones in the head out. Yeah but at repco we got them on shelf usually and if we dont she have them by the next working day.

Hope this helps ya

Easy,
Just bang them in (they won't drop anywhere) then use multi-grips to rip them out.

welsh plugs cost about $3 each for brass ones and are easly installed and should be sealed up with a sylicone. when u replace one and u should replace all of them because u have the engine out and one behind the flywheel is a [Naughty Pottyword] of a job to replace when every thing is in the car.

Never use silicon use the non hardening gasket goo. Silicone does block everything.

Hi All

I have a VN Commodore sedan and unfortunately it is replacement of welsh plug time.
My question is, is it easier to remove the engine to do the welsh plug replacement or is it easier to attempt to replace them in situ, systematically lifting the motor from side to side removing the exhaust manifolds after unfastening the engine mount replacing the plugs . In addition to this the rear crank seal could do with a replacement as well.

If the engine has to be removed is it advisable to remove it with the drive train attached or without. (Its an automatic) I have been told there is a right and a wrong way of doing this with or without the drive train I'm not sure which is what.....

for autos i just undo the converter from the flexplate and a few hoses n stuff then pull the engine out leaving gearbox supported in car, manuals i pull the box with engine 90% off time. thats just how i do it but it comes down to personal preference.

long live the hemi

Hi
I have read the comments above and saw it asked a couple of times but nobody answered. Do you need to take out the whole engine in a VN to replace the welsh plugs? We are in desperate need of replacing our plugs but do not want to take the engine out unless we have to. Could somebody please answer on wether you need to or not?

Hi,
I just had one plug replaced in my v8 vn.
The mechanic suggested removing the engine so all could be replaced.I almost had a fit thinking of the cost so i decided just to replace the leaking one.I havent got the bill yet but he told me it took him 3 hrs to remove the exhaust and other stuff in the way.

I don't know much, but here's a quote from http://www.phoenixme...

"the welsh plugs used in V6's are steel and not brass. The idea of this is that some corrosion is imminent, and it is cheaper for a $1 welsh plug to be corroded, than other more expensive aluminium engine parts. Problem is, V6 welsch plugs are in a prick of a place, and can be awquard to change."

Hi there I was wondering if I could get some advice. I have a 1999 Holden vt berlina I had water issues and had the radiator water pump and thermostat replaced. I am still having water problems and a leak underneath the engine from what I can see. The water problem comes and goes the only thing I can think of is it being the welsh plugs. I had to put 6 litres of water into it recently left it overnight and refilled the radiator the leak only seems to be there when the engine is under pressure. How would I identify if it is a welsh plug? Also would the valley gasket cause this major leak?
