Default Airfilter drenched in coolant?! Help?

I have a 1995 LS400 that ran amazing till the started went out....SO I took on the challenge of replacing it myself...took off the air intake assembly, the throttle body, upper and lower intake, injectors, rear water bypass, and ect. to be able to get to the starter..

Replaced the starter and put everything back together...The car turned on first try no problems!
ran great then out of nowhere it sputtered and turned off...When I took a closer look I saw my filter throttle body and plugs drenched in coolant....WHAT WENT WRONG?
all coolant hoses where in the right connections.

pull all the intake tubing off and see if there's water in the intake manifold. sounds like you missed a gasket or hose connection.

Take it apart and do it again, with fresh intake gaskets and paying closer attention this time.

Took apart the intake and gaskets where wet but no coolant was really visable...unlike the airfilter, throttle body and plugs. Taking my time putting it back together this time...I did notice that someone bypassed the heater control valve? connecting the rear bypass tube to the one that runs down from the front of the engine...could that be the problem?

looks like that someone needs to be reprimanded for doing such a thing! the valve can be bypassed but not taped into the intake, if that's where it's plumbed to.

Do you have a pic of where they ran the tube? The reason I ask is because of the size of the tube it can only go in so many places.

it looks like the tube to left of the starter is connected to the inlet right next to it...
