If the thermostat is Ok then the radiator is doing nothing until it reaches working temperature anyway. Only real suggestion would be a coolant pre-heater, very regular oil changes and/or or a good motorway run every so often. Struggling to see how much water is getting into the intakes, though. Condensation from the breathers, you reckon?
Yes, condensation, and loads of it. Very pure water in some places, brown mayo in others. Evidence all the way from the breather box by pot 5, all the way to the puddle at he bottom of the bag pipes. Y shaped breather pipe full of brown goop, but only on one side.
There is now a problem with the top hat/D shaped seal on the Eco tech breather box to plenum. And the breather seals/o rings on the section that extends forward to the throttle body, as air is now leaking in after re assembly when the seal was seen to be perished/trapped from a previous re fit.
That might explained the uneven air flow per bank. ...it might also explain the the condensation in the first place. Period. Thing is the audible air leak wasn't audible before. There is now a rapidly decreasing air hiss once the engine is switched off. Clearly the water was evident prior to, and missfires evident via pedal trick. (But not maxiscan

)
Obvious one is to replace the seals and see if air flow through the breathers improves which it undoubtedly will. But the short journeys will remain.

Recomended replacing the relevant seals, but thought I nice chat on the subject wouldn't hurt in the mean time.
