Welsh Plug

[bunta08]

ok so a couple of days ago now i was driving down the road and heard a pop noise so i looked in my rear view mirror and i see a whole pile of steam behind me. So i drove the car home seeing as i was at the end of my street and popped the bonnet to see where it was coming from but i couldnt see a dam thing so i just let it sit there over night wondering what could have blown.

next morning i walked out side and had a look, checked all of the hoses and everything but couldnt find a thing till i checked the welsh plug at the back of the head and to my surprise apparently i blew the whole middle of the welsh plug out and only the outside ring is left

so my question is, is there anyway i can replace this without taking the whole engine out? or am i just gonna have to suck it up and remove the engine?

What motor/what car? most likely be an engine out job i reckon. . . . and while you have the engine out it might be good preventive maintenance to replace all the other welsh plugs as well

twincam rb30 in a r32 and yeah well if i have to take the engine out i might as well double check everything

Facing the exact same problem.. RB20DE engine has lost its welsh plug at the back of the engine.. Right up against the firewall... I can stick my hand in there and feel around but really cant do much else without taking the rest of the engine out... I did hear about expanding rubber plugs that can be used? I couldnt find any other info on this tho.. As I dont have the facilities at home, how much would I be looking at if I took it to a shop and they had to lift everything out etc etc..? Better off even dropping a 25 in, cost wise?

yaeh, might be easier to drop the 25 in there, but change the welsh plugs on it before you do!
