Its quite hard to say really. Its definitely Crema thats coming over the top, but I still feel like it might be due to an overflow from the group seal. When it doesn't overflow, the flow just isn't the same, its hard to explain. I will try to make a video in the near future, it'll be easier to show.

Well, I couldn't have it leak this morning, most likely because the coffee is now a few days old. However I still took a video to show the steam coming out when you pull a shot as soon as the light comes off.

Possibly, but I'm not sure if it would fix anything. There was actually a site where the guy tried such a thing: http://www.coffeetamper.com.au/kb/imat/tips.html#wormholes But he says he basically didn't notice much of an improvement.

Quote from site:
" .......The only potential issue caused by the diffusion disc is a possible slight reduction in effectiveness of the 3 way valve, meaning pucks may not be quite as hard and dry as before. This though is largely theoretical, I haven't noticed a great change myself."
I take that to mean he is referring to the 3-way valve function, Not mentioning the potential improvement to the shot extraction quality. Maybe I didn't read far enough,.... The design he used is what I had in mind. Brass shim stock is easy to work with. It cuts with scissors, a needle or micro drill for holes.

i am so happy to find this thread. thanx @h3yn0w for the rundown of the issues with lelit. now i see the reasons of the problems. especially with the bitter or too acid espresso. the thing is my lelit sometimes behaves ok for a week and then "misbahaves" for weeks I did not know why. But I was always suspicious about the "too hot water" issue. I made this silly video about "Bikini portafilter" but you can clearly see that initially the water burns the coffee. http://www.youtube.com/watch?v=I6Qibx0nY4o . Is there a way to adjust the temperature of the water? Changing the thermostat or something?
The best way to control the boiler temp is with a PID. It won't really help with temp stability DURING a shot, but it will let you set your starting temp pretty accurately.
Or you need to temp surf. Wait for heater to turn off and then either a) Start shot after X seconds b) Blow off excess pressure via steam valve before shot. c) Flush group a couple seconds before starting shot.

Option d) put a thermometer probe on the boiler so you can tell what the boiler temp is and how the machine behaves during the thermostat cycle and cooling flushes.
