Ok so so bare with me as this can be long winded.
So as the internet makes everything huge. I thought I would address a way to help reduce carbon build up or coking as it referred to on the intake valves of DI engines.
So to start off where does this come from? Well as your piston takes its compression stroke certain gasses get past the rings and pressurize the crank. When the crank case is pressurized that has to be relieved. So to save the environment the industry came up with a pcv valve to avoid vent to atmosphere. What this does is a series of baffles in a plate on the front side of our engines. And continues up to the intake. The theory is you add the extra crank pressure back into the intake and hope the baffles in the plate catch most the vapor and oils before the intake. But as we know it can’t catch all.
So several ways have been addressed for this. Such as better breather plates for the pcv with more baffles, and catch cans.
Now hear me out. I believe I have a third cheaper option.
Upr breather oil cap. So what this does is have a weighted ball that keeps vacuum while idles but once you get enough pressure it lifts and elevates it. Now since the timing chain and other parts are connected to the crank. This should in turn relieve crank pressure thus eliminating a lot of strain on the pcv valves also. Which would not have the extra pressure or gasses pushing up to the intake. The less gas the less coking of valves.
So far it seems to be working. I’ve been testing this on two ecoboost engines and at 120k they seem to have almost zero carbon build up.
So it’s only two but both have no more carbon or less than a port injection engine.
I stumbled upon this with my built focus rs just to remove crank pressure and the lightbulb went on.
These parts are only $65 and much cheaper than anything else. Plus it’s as simple as putting your oil cap on.
