Like the title says, I'm installing a new APS Billet Plenum Plate Deluxe Kit (99 Ram 5.9). Is there anything else when replacing the plenum that I should make sure is new as well like the pcv valve? Thanks.

 

Heater bypass hose, Torque to yield bolts, thermostat, check and clean egr, oil change when your done. I ran it then changed it again in 5 miles, still had coolant in the oil. Now would also be a good time to change the cap/rotor and cam positioning sensor. Just easier to access. GOOD LUCK!

 

wait, so if ur plenum gasket goes, the antifreeze can get in your oil?

 

No, when you remove the intake manifold, you get coolant in your oil.

 

No, he must have had another issue.

 

No, when you pull the intake the coolant runners still have coolant in them, gravity brings it into the engine through the valley. Hense... Change the oil.

 

I thought you were suppose to drain 2 gallons of coolant out before you remove the kegger?

 

Coolant hides though. It waits for you to give it an escape, and then runs into the places you least want to see it. Coolant is just like that.

Even draining it down, there is still a good possibility some will be trapped in a location likely to cause you trouble. I think the engineers design them that way.

 

novice question. i have the v6, should i be as worried about my plenum as yal v8's? and if so how do i check if its bad?

 

Excellent. Thank you!
