Hello again, I haven't been here in awhile. 2015 Ranger 570 full size.
Cold weather finally settled in for good and I hadn't started my Ranger since it was warmer and heard a real nasty loud squeak/squall to where it sounded like it could be metal to metal, being I've never heard anything quite like this sound before. Kinda like a duck call. lol.
Not wanting to start it any more I went in to the clutch (Dura) area since that was the last thing I did to the motor and everything appeared normal. So I rotated the clutch by hand to see if I could feel metal to metal,... thinking piston, or ring maybe and nothing felt wrong. Ah! good sign! Rotated the clutch by hand past the compression stroke and somewhere after that I heard a smaller example of that squeak. Found it was coming out of the return hose to the air filter from the crank case, cause I had the air filter box out of the way and just that hose open and close by. I found the sound would come roughly during the up stroke of the piston. Got to the point where I would put my thumb over the hose, rotate the crank, stop and then remove my thumb to hear it, which made me think it was a air flow issue and not a metal to metal issue. Ah! better sign! Also found removing my thumb let air in not out.
So I thought at that moment (not having looked in a manual yet) is there a check valve and it's failing!
Researched and didn't find much about this issue but found a new one and ordered it (~$25+ and comes in next thursdayish) even tho I haven't removed the old yet to look at it.
Anyone else ever have a squawking breather valve. Lol!
