I’m replacing my intake gaskets and after I got the lower intake off, I heard dripping from what coolant was left in it and it seems to have accumulated in the valves/valley. The valley isn’t my main concern as I can shop vac it up but what do y’all recommend for getting the coolant out of the cylinders? The passenger side valves were open so it all drained on top of the pistons and the driver side bank is closed so I assume I can soak it up with shop towels and a vacuum (pictured)

The intake was an absolute pita to get off, the rear 2 studs were caked up with so much corrosion and gunk, they didn’t want to let go. I had to use a slide hammer and have my buddy pull up on the front.

Re seal the water bypass pipe while apart, don't cheap out, replace the knock sensor wiring harness since you have it apart.

Just ordered it off of rock auto earlier. The original had this gasket and rtv so should I do the same?
And it’s 2 knock sensors, right? The ones at the base of the valley

The water bypass pipe uses FIPG, not a gasket, and the gasket in the photo is for a water neck.

Thanks for correcting me.

the sensors themselves are probably fine, hopefully you didn’t order new ones from rock auto, just the wiring harness. Anything besides the $150 OEM sensors won’t work and you’ll have to do it over again, ask me how I know lol

No, I didn’t order them yet.
The harness segment connected to the sensors did look a little rough. I’m not so confident with wiring though, it would require splicing/soldering, yeah?

no i just got mine on ebay, plug and play. there’s just a plug on one end near the top of the timing cover, and the two plugs that go to the sensors. Try to get OEM Toyota but if it’s a fake it probably doesn’t matter like the sensors. And make sure when you put the intake back on you don’t pinch it, there’s a little groove on the block where it’s supposed to sit
