I have read mixed reviews about those Fumoto valves. I don’t think you are alone. Many have complained about the drain speed.

Yea it takes a while. I usually go back in the house for 30 mins or so. I bought some plastic tubing that fits over the nipple and run that into an oil jug

Got up into the 50s and sunny today....Tahoe was covered in gravel dust and mud from driving through road construction in the rain a few days ago....so it got washed, glass cleaned, tire dressing, and ceramic waxed. It looks soooo freaking good. Also did my wifes car, which completely finished off my arms ( rock climbing last night started the process ) but they both look so good now.
Uhh... pics..?

No you can't adjust the opening, it's either open or closed. And since no one really made a vacuum cutout for 3.5" exhaust, I had to kind of Frankenstein parts together. I had to weld the cutout to the flange after I cut the flange down a bit and used butt joints to tie it altogether. I might eventually weld it all up. And I mounted the vacuum pump/remote relay under the cupholders in the center console.
3" Vacuum Cutout
3.5" to 2.5" flange
3.5" Stainless Cutout
3.5" Butt Joint Exhaust Clamps (2)

I thought it was actuated by engine vacuum (or, more accurately, lack of with throttle angle). That's why I asked if you could adjust the opening point. Wouldn't want it opening just when you're casually accelerating from block to block.

You got a deal on that cutout!

Ohhh, yeah I guess I should've elaborated more on that! I do think some people in the turbo world have them hooked up that way. This one has a pump.

I too thought that was how it worked.

Got it washed Saturday. Found that the clear coat on the passenger side has bad clear coat peeling as well as some on the roof. Anyone know a good process for me to fix it myself?

Today I decided to take care of the po121 code and cleaned the throttle body. Then I used the sea foam spray deal. I was one of the unlucky ones where this thing did not want to relearn the idle. Did the whole turn on 3 min off 60 for who knows how many damn times. Unhooked the battery for 10 min. Ended up having to drive it for awhile. It finally figured it out when I got home.

I did notice it seemed like I might have a slight boost in mpg from seafoaming though. I was monitoring the instant and usually up a slight hill I get 10 to 12. It was reading 15. We will see if it’s a placebo effect after the next fill.
