Oil leak ?

Hello All, I have an older ('94) White 314-646F190 snow blower which is powered by a Tecumseh 8hp HKSM 80 engine. While tipping the entire unit on its side to clean it, I noticed that oil was draining out through a black hose which is attached to the Tecumseh engine (carb. side). The hose comes off the engine straight out from the side and then is angled 90 degrees down. My 1st thought is that theres no way they would construct an engine like this in such a way that an open tube runs from the crank case of any engine, for whatever reason - makes no sense to me but hey, I'm no expert. So, I'm figuring I have a real problem on my hands (?). The motor hasn't been run now in several years as at the start of the winter season several years ago, the engine (electric start) turned over but would not fire up. I assumed, after replacing the plug and still having no luck, I had a fuel line/carb problem. Now I'm wondering if I haven't some how ruined the engine. Can anyone tell me what this black hose is for and, if its allowing oil to pour out of the engine, is this the major problem it appears to be to this newb ? Thank you so much for any help offered !!

Thank you do much for the quick response. Funny you mentioned cleaning the holes on the bolt. That was what I was about to do before I tipped it on its side. It had a layer of dirt baked on from winters/rain/sun in the summer over a period of several years sitting outside - guess the tarp didn't work as good as I thought :-) So, I decided to scrub it down and then tackle the carb. I had just did the same procedure on my Briggs/Stratton lawn mower engine after it wouldn't start back in May. I tried everything to no avail then read, maybe here, can't remember, about those holes getting clogged. I thought the odds of this being the problem were 1 in a million but, after passing a small paper clip wire through the hole, the dang thing started on the very 1st pull !! Everyone should know about that little procedure - how many people have wasted how many machines and $$ over the years because they didn't know about this one seemingly insignificant 'weakness' ? Anyhow, yes I will follow your instructions and hopefully find I have compression etc. I wish I had written that I've pretty much decided to buy a new carb. for it. I've seen them for less than $100. ('Oregon' ?) so I'm thinking I could save myself mid winter blues starting out with a fresh one. You went and typed all those directions ... I'm sorry for this. Maybe I'd have to do this anyhow with a new one ? New territory for me - my experience is limited to changing the spark plug and now, the paper clip trick. If you have a second, could you just give me a quick idea of what that hose is for and is it an open 'channel' to the oil ? I just can't imagine that an engine would be designed to permit oil to pour out like this just because the engine is on its side - but what do I know ? Ha ! I've been around small engines and car engines all my life and my understanding is that oil reservoirs of any kind would be sealed air tight... if this is a dumb comment, my apologies - 'being around' engines doesn't mean 'knowing everything about engines' :-) Again, IF you have the time - otherwise I thank you again for the time/knowledge you've already volunteered to help me out !

Thank you once again. Yes, the PVC valve - this is why I was confused. 'Vented' but sealed. I will let ya know how it all shakes out. Best laid plans of mice and men - my son shows up yesterday with an expired inspection and throwing a code for O2 sensor. It sounds like a cracked exhaust manifold to me so maybe causing the code. Before he racks up a bunch of tickets, I'm gonna have to get on this project 1st now. Never ending :-)

I've always heard "if it has fluid in it, it has to breath". I need to get around to extending the breather hoses up on my jeep for the axles and transmission before the great floods come at the end of the world in December :) -Dan
