Just as the title states. Today after a 5 minute idling warm-up, (15* temps) I hooked onto my snowmobile trailer to put it away with my '04 Scrambler and just as I got onto the quad & before I could even touch the throttle a huge explosion took place.

I immediatly turned off the engine not knowing yet what happened and looked over to see 1/2 of my oil tank laying 25 ft away in the snow & other various pieces on the righthand side of the quad & oil everywhere!! Yes, it was very violent!!

I have not yet investigated, but my only simple thought is the crankcase vent tube being iced up?? Dunno?? But I would think it shoulda just blown the line off the fitting before the tank would explode??

Any other suggestions are greatly appreciated.

 

ebay has an aluminum one for bid right now i believe,its only should be 20psi. maybe regulator stuck closed,i'd put a guage on it RIGHT when i restart it!

 

Mechanike, thanks for your thoughts. Where is the regulator located??

 

i actually don't see one it might be regulated through design,does your filter have a bypass valve in it? i cant imagine the vent screen gettin that clogged.....

 

The filter doesn't to my knowledge. Iceing is the only thing I question on the vent line. It's last oil change was in November, right before it got cold here. I was playing pretty hard 3 days ago in the snow, ( alot of snow build-up on the machine) but had it in the garage to thaw out afterwards. So, maybe moisture & iced back up?? I'll try blowing thru the line in the morning.

I would think that the circulation would do most of your pressure regulating in the tank. As oil goes out oil goes in, and so on. Make sure the oil can get back out into the engine. Doc
