I have noticed that my Cold Start Engine Vac signal is 14". Once the engine if fully warmed up (a good 15 minutes of driving), the vac will be steady at 16.
Just looking for theories as to why, I don't think anything is wrong.
Mine
Forged Al pistons fit smaller in the bore when cold, so vac increases with piston temps.
Oil temperature/viscosity influence ring sealing (but I have a hard time seeing it have this much of an impact).
I look forward to hearing your thoughts.
