Now that the temperatures are plummeting, AOS w/o coolant heating that I installed at summer is really bothering me. In other words I’m afraid that it will freeze and lead to catastrophe. Before when I had Saab 9-5 which was notorious for clogging oil sump strainer I made a display for oil pressure from VDO oil pressure sender, pic microcontroller and display for readout. I was thinking the similar solution here. Instead just using buzzer and hiding these behind the dash. Program it so that at low pressure it would beep slowly and higher the pressure, higher the beeping interval. So that it would be completely hidden until there is a danger. When it would beep, you just pull over and let the engine radiant heat melt the AOS and hoses.
Where would the pressure sender be located? If there were any unused plugs on top of engine, that would be perfect. Anyone knows is there? Other possibility is the front breather located under the alternator, install T-fitting to the hose as close to the engine as possible. Back breather under the intercooler won’t work as there is pressure when in boost.
I measured the needed force for dipstick to lift off and calculated equivalent pressure to be ~2.7bar / 38psi. Which is quite high. I wonder would some of the rubber seals if any pop off before that. Due to not knowing is there some other place giving up earlier I was wondering to set the alarm starting from 0.2bar to 1bar (3psi-14.5psi). Basically my understanding is that in any case there should be no pressure at all in the engine when everything is ok.
What are your thoughts? Am I being paranoid, or does this make sense? Of course maybe easiest would be just slit the hose longitudinally inch or so and it would release the pressure if necessary..
