Yes it has a good (looking) ALDA. It wont hold a vacuum though.

Im confused about how this is built inside. How would you soak it? It seems like heating up to 200 degrees in an oven might be the only way to really dissolve that stuff. ?

I assume the internals are bathed in oil to some degree so the part that could theoretically be affected by the WVO would be only exposed to the fuel path. So I'd soak it via sucking in solvent at the intake and turning it by hand until full?

How would the WVO have affected this if it showed no issues months after having just one tank of WVO put through it? What I can see at the outlet and inlets show no signs of any crud. This also had a purge treatment or two until it was finally pulled off the motor.
