Front cylinder oil reserve welsch plug

[aussieal72]

Hi guys well after a few headaches and some serious bleeding we found the source of the blood loss on the ol girl.
There appears to be a small plug of sorts like a welsch plug at the front of the front cylinder it appears to be only a few mm in diameter. Oil is slowly seeping out. Does anyone know the correct name for this part and how to obtain one . Thanx in advance

Cam plug?

If it is the cam plug, many guys have been successful cleaning the area well and sealing around it with a high temp sealant. Saves a lot of work.

Ok cheers will try and take a pic and also clean it up good and through some sealant in it

Yep. Pictures. A few millimeters is really small. Much smaller than the cam plug which is more like an inch (25mm) in diameter. Also the cam plug is on the side of both cylinders, not the front. I'm looking around on mine and don't see anything that fits your description.

Quite honestly I had to look up welsch or welch plug. I had never heard that term before. I've always called them freeze plugs.

Funny, what you call freeze plugs, we call frost plugs here and if your lucky they may pop instead of a block cracking if it were to have only water in in cold weather, but really they are holes in the water jacket to facilate casting most automotive blocks. Not sure if they exist on the nomad motor and oil would not be coming out of anything like that.
As mentioned pics would solve what the op is referring to.

Yep. Other than the terminiology used to describe, I've always heard the same information regarding freeze/frost/welch/casting plugs. Real curious as to what this deal is all about. Hope he posts some photos. From his description it sounds more like a threaded pipe plug, but I saw no such animal when I checked mine this morning (unless I just missed it).

My old Ford big block boat motor had a rubber freeze plug in it with a bolt/nut and a couple washers so it would expand and seal the hole. It was kind of handy due to jetboat blocks getting sand in the water jackets (cooled directly via the jetpump with lake water and no sand stainer etc.). You could pull the freeze plug, put water pressure to the block and flush it out. One day it spit one out and it went over the edge and sank while way back on the lake. With a jetboat, if the motor is running it's pumping water through the block. If it's pumping water and you're missing a freeze plug, you're filling your boat up with water. Found myself on the wrong end of a tow rope that day. Couldn't start it or it would swamp. Next day I was replacing those rubber ones with some brass freeze/frost/welch plugs.

That small of a hole sounds like cam chains have cut the sparkplug tube and oil is weeping out the rain water drain.

Doesn't seem that way from the op's discription, front of the front cylinder, small welsh plug. No pic's we might as well be playing I spy with my little eye.

The front of the cylinder has a little hole right here.



There are no welsh plugs or freeze plugs. He thought there was supposed to be a plug here. If you stick a pick or wire in this hole it will come out inside the sparkplug tube outside of the engine. This lets rain water drain out of the tube, otherwise it would pool up in your sparkplug tube. If your camchains cut through the sparkplug tube or the o-rings on the sparkplug tube quit sealing oil will weep out there.

Go out to your 1600 and try it.

Thanks For posting JP that's the hole I was referring to in My answer to Him but We are still waiting on pics .

yup and wicked nice shot in a mirror ... if that is the OP's hole he has a problem. The fix will be a new plug well insert and 2 O rings.
