MAYO, Oil filler and CCV tube and cleaning with Break parts cleaner

[j_lopez]

Hi, I am new to this forum (Well new to any as this is the only OL forum I have subscribed with so far )

My CCV has been replaced by a thief Uh!! sorry i mean mechanic and i believe that it was the cold climate type as it was insulated however, he did dot replace the oil dipstick to the updated one. So Long story short, when take off the oil filler cap I see the MAYO in the cap (Very cold weather here in Winnipeg -30C) then I suspect that if there is mayo in the Crank case then definitely the hose running down the ccv unit will be no different. And after pulling the accessible hose end (upper end part of the hose) the one connected to the crankcase cover I saw that It has MAYO buildup in it. I noticed that in the oil filler cap a few squirt of the a Brake parts Cleaner does the job of taking out the mayo. Here is the question I have for you guys I need help with. With the hose that is leading to the CCV unit (The one attached in the crankcase) I am going to pull that end and clean it with the brake cleaner to take out the MAYO. The Brake parts cleaner will of course drain down the CCV unit and then to the oil pan? is that a good move or a bad one? my objective here is to at least get rid of some of the MAYO. Please advise, thanks
