oil leak around intake manifold hose

Hey folks, I have a 2000 7.3 psd, It is leaking oil around the boot that connects the intake manifold(spider) to the head on the drivers side. It is enough oil that it leave a puddle in the valley and I have to add oil every week or so. Do I need new boots or is there somethin deeper wrong. Its not the HPOP or the HPOP hoses or the pedistal or Turbo orings, all have been replaced and no leaking around them the only place that is noticeably oilly is around the boot (which gets on the outside of turbo and into the valley). Or is it a deeoer problem? tanx

sounds like you need to do the ccv mod bud thatll take the oil out of your intercooler and you wont see the oily mess around the boots, and ya new boots in the valley sounds right in your case. lets see what everyone says?

How much are you adding every week? I would degrease and see how fast the oil puddle shows up again. Also drain your water separator into a clean container and see if the fuel that comes out is the normal color or if it's dark from engine oil getting into the fuel.

Could it be injector orings leaking? I had them replaced not quite a year ago and 1 injector leaked already(the guy used cheap orings). I'm gonna clean er up tomorrow and check the fuel from the water drain. tanx,

I wipe it down, changed the air filter then drove it bout 50 miles. When I got home there was a little oil in the valley. Not at the back around the pedistal but in the middle right under the intake hose on the drivers side. Just above the hose was a little wet (oil) along with that side if the turbo. Could it be the turbo?

Also I did check the fuel from the water separator valve and it look like diesel (green).

wipe your finger under the bottom of the hpop and see if you find oil there. How much are you adding?

I wiped under the HPOP (It has been replaced) dry. No oil in the front of the valley. Checked both HPOP lines dry where they go into the heads and connect to HPOP. Would valve seals make it smoke when starting and leak the oil where Im havein the issue? Had to add bout 1/4 quart of oil after drivein bout 60 miles.

Take your oil cap off with it running flip it over and set it over the hole and see if it stay for a sec or two or if it blows it off right away.
