Engine decoke (Terraclean)

Nice, thats the difference between FSI and injectors before the valves.

I don't think the terraclean would have made much difference to the valves tbh but what it may have done in the combustion chamber I cant say.

I did watch Ed china doing it to an old Jag?? and it made a massive difference to the emissions.

Glad you finally got round to doing the return valves, has it cured it?
