Whoah! Just after I added the glow plug oil and put the plug back on, I gave the engine a pull and then a whole bunch of bubbles appeared around the glow plug!!! The plug is properly installed, firmly but not overtightened....coming to think of it, I did notice this before once when I was pulling the starter.
Any ideas? The engine is working perfectly, but I want 2 know what this is!
The washer that goes on the glow plug, this isn't directional is it?

No the washer is not directional, you could flip it over and install it that way is you want. I would keep the washing installed the same way though because it was already grushed to fit the glow plug that way and it will make a better seal.
Make sure you have a copper washer installed between the glow plug and the head to make a proper seal. If you do have that washer installed maybe it is cracked, warped or worn out, I would replace the washer as my first trouble-shooting move. My next move would be to check that the glow plug is not cross-threaded and it is going in straight so it will be flush with the head. If that checks out then replace the glow plug. If after you replace the glow plug you still have a problem you will have to inspect the head carefully for any cracks
Good luck.
Thanks Joe
Yeah I noticed the problem right before I even took the plug off when the engine was brand new, so I am guessing it could be a faulty plug or bad washer. The plug is going in perfectly straight and it is definatetly not cross threaded as the thread on the plug has not been damaged and it screws in without any resistance. I'm gonna go and get another plug/washer today and try that. If not, I'm guessing theres an air leak somewhere around the hole.
Engine performance doesn't really appear to be impaired as I don't believe its a major leak, but still it is a real pain! I rang OS support and all the guy could tell me was that my plug was threaded, which is certainly is not! If there is an air leak somewhere down there and it is a manufacturing fault, I suppose I can just send them the heatsink head which has the glow plug hole and thread inside?
Never had any air leak trouble with my T-15!
