because this motor is DI, I assume it might be worth while to apply some seafoam during an oil change. in the past, on a wrx, i simply attached a small hose to an available port with vacuum and slowly trickled some in with a tiny funnel. changing the oil this time i could find no obvious vacuum sources. the goal is get the stuff in short of the intake so that it hits the back of the valves where carbon/oil tar builds up on DI engines.
any suggestions or is this worth while doing?
thanks for any info.
