My routine maintenance to CCV
 

Give it a good "suck" once other week during coldest weather, I'm sure she'll love it!!! :bustingup

So far so good. So anyone who is interested, a hand vacuum, and 1ft of tube will do.

Good Luck!

I think I like the idea..... :thumbup:

Where you pulling from the hose by the valve cover?

I still would be sure to have updated to cold climate CCV first, as the insulated design is better

Why? If you leave it out overnight it will all be at the same temperature, inside and outside the insulation. Same likelihood of freezing.

Yes, it's the returning hose to the upper valve cover. Just gently press the ring and pull it apart. I won't recommend doing it if the hose has become brittle.

Hey Bobby, I kinda agree with JCL. The cold version seems to me just slow the freezing process. Eventually it'll be the same likelihood of freezing.

My ideal solution is wrap up these hoses and draw current from the battery to keep it warm. Of course, you gotta have a 1 MWh battery.:D

I meant if you were on the original valve and hoses. The insulation does just slow the process I will give it that.

Going back to pcv as a maintenance item, at our X's being between 8-14 years old, if you have replaced once and see the cold temps I would be sure it was the cold climate version.

I see nothing wrong with this maintenance method on a system that has been replaced recently or in the past few years, but based on what I've read and experienced personally, if you are on the original system it's somewhat borrowed time.

This is just my opinion obviously.

Agree! Especially the price difference is less than a couple gallons of gas wroth. I'll go with the cold version if replace again.

Here is my take on why the insulation works.
when the engine is first started up all the mayo collects in the tubing. Since the engine and oil are quite warm, the mayo moves around a bit, from the valve cover to the oil pan and back again, all through the pipes, insulated or not. Once the engine is switched off, the cooling process begins, but also, the process of the oil (mayo) flowing back into the pan,through all the pipes etc. the insulation allows the mayo to circulate longer (flow back down into the pan) than if there were no insulation and the pipes would cool quicker. even a few extra minutes makes a difference! (molassas in january vs molassas in july!??)
While maintenance makes the most sense, getting rid of the mayo (technical term i know!!) is the root of the problem. the insulation allows the residual to flow into the pan rather than clog the pipes.
I agree that maintenance would be the smarter move, as would insulated (cold weather replacement) parts if needed. Ive also noted that the hoses covered with insulation have less "thermal shock" and become less brittle than ones not covered. rapid cooling and heating is what seems to make them weaker! just my $.02
:p: :cool:
