Welch Plug Removal. Engine Still In Car.

[White Spyder]

What is the best way to get the welch plugs out of the engine while it is still in the car? I want to remove the one near the oil fill tube.

Thanks in advance

I use self drilling, self tapping sheet metal screws with a hex head. Chuck it in the electric drill and run one down into the plug leaving the head of the screw high enough to slide the claw of a carpenter's hammer under it. Quick pull, like pulling a nail out of some wood and "Bob's your uncle".

 

I believe that Don C. uses the same method and has posted photos of it in the past.

Tod's method is probably the easiest however if you can't get a claw hammer in there for clearance replace the hex head screw with another with the same thread but much longer, say a  2-3" roofing screw or panel board screw..........with it screwed in, the extra length will allow some extra leverage and you should be able to use a pair of pliers or similar to wiggle it and remove the welsh plug.........andyd

removal is mirror of install (Page 135  of shop manual 46-54 Plymouth)  while the above method of screw threaded into the disc and popping out is much easier...the book says to continue beyond the flattening of the normal disc install and using a punch to make  a dimple similar to the way it look/is going in.... (only concave not convex as when new)...will then easily come out in your hand..the book is full of these tips and trick and also plenty of warnings/cautions on service to these engine..

I am either the only one that doesn't know what a welch plug is or the only one willing to ask. Judging from the picture it looks like a freeze plug. I've never heard the term welch plug. Where is it?

There is so much to learn.

Don..not to criticize but simply type welch plug into say the Yahoo search..immediate return with photographs..

I mean no disrespect but the amount of time spent telling me to look it up you could have just said "Yes." and saved us both time. I didn't want to make a class project out of it. I was just curious. Thanks anyway.

Don:

 

Yes we have come to know them as Freeze Plugs, but really they are not freeze plugs.  They were plugs in the block to help remove the sand from when the block was being form in the casting.  So they realy are a core plug.  They usually do not pop when the engine block freezes over as you would think by the terminalogy freeze plug.

 

Don do not feel bad about asking questions, most of us do not know all the answers but for some they are more knowledgeable about automivtive terminollogy.

 

aS WE WERE ALL TOLD IN SCHOOL, NO QUESTION IS NOT A DUMB QUESTION, It s just harder to remember as we all get older in life what the answer is to our question.  Even my 85 yearold father in-law still asks questions about his 31 Model A and guess what I am even learning from his questions and answers that we have during our discussion on the antique cars.

 

Knowledge is to be sought after and then also to be given forth to help the next guy down the lane, keep passing it on.

Here in Oz we know them as welsh/welch plugs as there is virtually nowhere here in Oz that it gets cold enough to "freeze" anything........... another type of plug we have down here are Butt plugs..........but(different type of butt) this is probably not the best place to go into that...........lol........back in my corner I go.........andyd

. . . as there is virtually nowhere here in Oz that it gets cold enough to "freeze" anything. . .

Not even at a place like this? http://www.opensnowmap.org/?zoom=14&lat=-37.14523&lon=146.45097&layers=&e=true&m=vector

 

Awful tough on the bases of your skis if that is true.

You're a bad boy AndyD... I always have a chuckle at your posts though!

[Don Jordan]

Thank you Rick - that was thoughtful.

[Andydodge]

Tod, o/k you caught me out.....lol...........but apart from a few places in the Snowy Mountains and Tasmania there aren't that many, nor over a large area.......I am on the NSW east coast in the Clarence Valley and our "winter" here got down to 1-2 degrees overnight about 2-3 times I think, we are now supposed to be in Spring but with temps in the high 20's I think Summers here instead..........regards, andyd
