Blue smoke at warmup and idle
I am getting a visible cloud of blue smoke when I cold start my engine, it gradually clears out over a few minutes as the engine warms up. I also get a very light puff when back on the throttle after shifting, and when free revving in neutral. Would this be the oil seals? I have about 2000KM since I installed this new to me motor, and I have not used any oil, I am running pre-mix, about 130:1 ratio (150mL oil per 20L fuel), oil metering system is removed.
One other possibility is that I have no fuel injector diffusers installed under my stock primary injectors, I am not sure if this would cause the fuel to not atomize properly, and since I am premixed, causing the smoke, since it only seems to smoke blue when it is supposed to be rich. I am running a standalone, and it is rich when this smoke is happening, under 12 AFR, leaning it up reduces the smoke, but driveability is crap, along with how it runs.
