i got fumes in cab, was looking over engine, no exhaust leak . but i noticed smoke/fumes comming from my dip stick and from some form of cap/vent attached to the valve cover. I pushed the dipstick down and that sealed. my question is , is it normal to have smoke comming from the crankcase out the dip stick and if i replace the vent/cap will that stop the smoke comming from there also is this normal or is something wrong internally?

 

There are o-rings on the bottom of the Doghouse, which is the cover thing your talking about.

It's part of the emissions return that ford put in.
People tend to loose the o-rings, break them, or what not and not replace them.

The doghouse should connect up into the intake on one end of it towards the front of the truck.

Clay has an o-ring kit for these.
If you want, you can replace them from ones from the parts store, but you'll have to do it again when they burn up due to heat.

You'll have to look in the SD section, the parts are the same though.

As well, it is normal for blow by on our motors.

 

We are adding to the OBS section by the day

Riffraff Diesel: CCV O-rings

 

Clay, you get my E-mail about adding that to my order a couple days back?

Edit: Thanks for the E-mail back Clay, Talk about customer service! RiffRaff all the way

 

awesome thanks Talyn, i am fixing to replace my fuel lines from the fuel pump, and put on my new diamond eye exhaust this week. and figured i would investigate the fumes . knowing the blowby is normal is a comfort. i will check out riffraft. i plan on investing quite a bit over the next year on this truck. thanks again.

 

Take a look at the up pipes to the turbo from the exhaust also.
