Oil Coming Out Of Dipstick

[CdnFire]

I have a 2004 Silverado 2500 with the 6.0 gasser, I got off night shift and it was -38Celcius (-36 F) and went to drive 4 hours to visit my parents. The truck block heater was plugged in all night and I let the truck warm up before I started off on my trip. I stopped about halfway through my trip for a bathroom break and noticed a bad smell coming from the engine compartment. I opened it up and the dipstick was pushed up a little from the tube and there was oil everywhere, I ended up adding 2 litres of oil to it. I finished the trip and added another 1.5 liters to the engine to get me there. Anyone have an idea why my truck is doing this?

 

Thanks

you crankcase breather is probly frozen off, not sure were it is located on your vehicle but there should be a hose comming out of a vavle cover that goes into the intake... may need to pull it off and check for a restriction

[CdnFire]

is the freezing of the breather because I dont have a winter front? would this help?

HOLY CRAP MAN!

Hope you get it figured out.

I case you did not know:

 

-40 degrees C = -40 degrees F

So do you consider that cold? because I have fought house fires when it was -52C and the windchill on top of that

At those temps, are you using synthetic oil?

 

If not, your dino oil is like molasses. If there is a PCV valve on your engine it is probably frozen in the closed position, allowing blowby gases to build up in your crankcase pushing out the oil.

use regular 5-30 oil, not usually that cold up here. I dont think the truck has a PCV valve. I am wondering if the vent lines and stuff are just getting frozen by the wind at hiway speeds with the air coming through the rad. wondering if a winter front will help.

at those temps, I would say youre on the right track! Defrost all the vent stuff they reccomended and get yourself a grill cover.

 

All the trucks I saw on the Ice road truckers show Had vinyl covers over the grills. Temps ranged from -14 to -50 some. In Northern canada/alaska

PCV valve is located at the rear of the drivers side valve cover. If it's frozen, any pressure will look for another way out of the crank case.

You sure you didn't just fail to insert the dipstick all the way in last time you checked your oil?

Positive I didnt do that

Would you admit it if you had?

PCV valve is a good bet. Cheap to replace. I wouldn't take the risk of cleaning it, I'd just slap in a new one.
