CCV on my 06N62 - Concern?

[JCL]

It isn't caused by winter driving, it is caused by condensation. Lots of short trips, not warming it up completely to burn off the moisture, the moisture forms an emulsification with the oil mist, and then it collects over time. If you do experience winter temperatures, this is the condensate that can freeze and plug it the crankcase ventilation system.

Clean it out with a standard solvent. Check for soft hoses, and do those at the same time. Check the oil separator for any damage.

It is a reasonable idea to do a hot oil change, but that won't impact this as this component isn't in the oil circulation path so it won't be touched. If there is paste under the valve cover (check the oil fill cap) then the hot oil change will help clean that out.

Best solution going forward is to get it good and hot every now and then, as it was designed to be. What you are seeing here is a symptom of not doing that, not a problem in and of itself.

**Do you mean the CCV hoses? and where is the oil separator? (sorry)**
**Can I use the TB cleaner? spray it in there?? and whipe or use compress air or would that damage?**

**Cap is nice and clean, never had or seen that goo under it**

**As in warming it up prior to driving? Also, should I change the oil now before winter storage? (I will change the CCV caps and hoses prior to oil change correct?**

Thank you JLC (fellow Canuck )

Where are you in Canada? Edit: I see Toronto below. Toronto gets cold enough that that amount of paste could freeze and cause a problem.

The separator is the device shown in your photos.

If there is no paste under the valve cover, then there is less benefit to the hot oil change, but I would still do one myself. Just one.

I wouldn't use throttle body cleaner or compressed air. Just use a rag and solvent.

Do not warm up the vehicle idling in the driveway. That doesn't warm it up and is much worse for it. As soon as you have oil pressure (about 10 seconds) and it is safe to drive (windows not iced up) start driving, gently. The damage and wear from operating the engine cold is related to how long you operate it cold, so the faster you warm it up the better it is for the engine. Just don't use any high revs, or high loads. By getting it good and hot, I mean driving it long enough and with sufficient load that you burn off the condensation that occurs naturally in the crankcase. This needs to be done regularly enough (weekly or monthly) so that it doesn't build up over time, as yours has. Or plan to clean it out regularly, which is a PITA.

If I was storing the vehicle for the winter I would do so with clean oil in it.
