New to the Forum-Intercooler Oil leak

[Glen IN ID]

I have a 2000 F250 with a 7.3 Powerstroke. I have recently noticed oil leaking from the couple between the intercooler duct and the intercooler. Is this normal or is there a problem I need to take care of. By the way, I do not like oil leaks. Thanks for the help.

Thanks, Besides tightening up the clamps is there anything else I should do, i.e. replace the coupler?

On the drivers side correct? Also tends to be leaky from the orange boots on top of the engine near the turbo.


What happens is the Crankcase gasses are vented into the air intake causing a fine oil mist to be introduced into the air intake and burned up in the combustion process. All normal. You will see a little doghouse on top of the drivers side valve cover. A small 3/4" size 90 degree angle hose is connecting the doghouse to the air intake. This is where the crancase gasses are being sent into the air intake. What happens is the oil builds up over time and starts to seep out through the intercooler boots.

Many people do the CCV mode to remove the crancase gasses from the intake and reroute them to atmosphere. Here is a link to the modifacatioin. The mod does not hurt the engine in any way, as a matter of fact this is how the commercial application of this engine designed. UPS Trucks, school buses, etc.....

Here is the link to the mod.

Thanks for the reply. The location is on the passenger side.

oops ......

forgot the link:

Welcome to guzzle's CCV mod web page

Some add the cannister to trap the oil, some just vent straight to atmosphere. If you run the hose along the rail all the way to the fuel tank you will not have a problem with the gasses.

Here is a link to a video, showing the CCV mod. The tube connecting the doghouse to the air intake was removed and 3/4" heater hose from Lowe's was used to reroute the gasses along the frame to the leading edge of the fuel tank. You can get an idea of how over time the crankcase gasses can lead to oil build up as the air charge cools. Which leads to the mess that everyone gets aggravated about......

I made the mistake of droping mine right behind the drivers front fender and somtines the smoke comes in the cab at a light or something like that. But I don't plan on changin it
