hose on DBC TB and valve covers Hello, I am pretty new to the LS world and was hoping for some help. I am putting 5.3 into jeep Scrambler. It has a truck DBC throttle body, intake and valve covers. The question I searched for but couldn't locate was in reference to the coolant crossover hose and the valve cover hoses and the PCV location. So somewhat in order
1. on the top of the TB is a large hole going up at 45 to the passengers side, appears to use a S type hose and go to 2
2. front of passengers side valve cover ,looks like same hole size as 1
3. bottom passenger side of TB small hole that has a hose that runs down the passenger side of the intake, behind it to the drivers side valve cover. At the drivers side valve cover and its a larger hole like in 1 and 2
4. coolant bypass look like it is small hole that runs directly up to the hole on the bottom of the drivers side TB opposite of the one in 3
it appears its the top of TB - passenger valve cover
and drivers valve cover to the passenger lower TB inlet
and coolant crossover to the drivers lower TB inlet
Seems like I am wrong here. I have read about folks funning something to do with the coolant crossover to the radiator or water pump to be high in the coolant circulation for steam
Also my valve cover doesn't have a slot for PCV valve, do I have one? if so where or pls let me know if I should add one
Sorry It wont let me add pics thanks for your help

The coolant crossover hose is a metal crossover that connects the front passages on the cylinder heads together and it routes underneath the throttle body. It does not attach to the valve covers. Note there are rear block offs on the back part of the cylinder head passages toward the firewall.
It looks like the picture below

The plastic hoses on the TB and valve covers is for the PCV system. Look at post #9 on this thread:

Let me know if you have other questions, good luck.
