welsh plugs

[carlie]

Ok this may sound like a silly question, but i have no idea and if i dont ask i dont know

when replacing all welsh plugs on an r32 gts-t does the whole motor have to be taken out :bs!:

[OVL-747]

it could be done with the block in the bay , but u will have to take almost every ancillary off , inlet and exhaust sides , thermostat will have to come out as there is a welsh plug behind it (i think so on that engine anyway hehehe)

best to do it outta car

may i ask why ur doing it?

one rusted/leaking?

[carlie]

yes one was leaking and i have had to replace the head, at first thought it was just a head gasket/

anyway i was told all welsh plugs should be changed ohhhhhhhhhhhh im so :devil2:

Easier with the motor out, also there's a plug at the back of the block that can't be reached without taking off the gearbox and clutch.

I Think that all the plugs that seat into aluminium are staked in, havn't looked at the block yet

Most of the plugs can be replaced with the head off.

The Nissan engine designers, in their infinite wisdom, chose to hide one behind the LH engine mount, and another one behind an elbow attached to the thermostat housing. And there was another one, in an impossible-to-get-at place, but I can't remember where.

My secret to removing them is to gently punch them (off centre) until they spin in the hole, then grab with vice-grips to pull them out.

Repco carry the right sizes (22mm and 30mm from memory).
