Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've got a few hours on a Husqvarna 8527SBE (8.5Hp Tec L-head).   Ever since I changed the oil (2 hour break-in) I see that after using the blower, there is some oil on the left side of the chassis.   The oil is undoubtedly coming from the crankcase tube and is not a lot (maybe 1 square inch of oily stuff).   

I used the recommended viscosity of oil, and I have not over filled it.  Since changing it, the oil level has been halfway between "add" and "full" on the dipstick when screwed in. 

Should I be concerned, or is this normal?

LP,

Oil leak not normal!!

Drain tube or oil fill / dipstick tube

Make sure they are screwed in tight!!!

Loudpedal,

I agree  to what jubol has said , also there's the possibility that the breather could be bad.(pin holes blocked or the breather valve stuck).Check to make sure that the rpms are not out of wack.Over revving is the cause for this a lot of the time. Around 3500-3600 should be good .The oil cap on the tecumseh engines should not be screwed in when checking the level.26 ounces for this engine.Hopefully you don't have anything more serious then that . Happy fixing, Snowballdgs.

I agree that is not normal but why they put a tube on? Is it a kind of modulator or something manner with crankcase pression?

Thanks

Denis

It is a crankcase breather valve, similar to the PCV valve on a car engine.

DNK1 thanks for the explanation.

I might be off base, but with new or nearly new engines, too much oil in the engine is the leading cause of oil coming out of places from which it should not.

You advise, with the dipstick screwed in, the oil level is halfway between full & add. Depending on several factors, it's possible your oil level may indeed be on the high side. Check the operator's manual to see if it says to screw in the dipstick or not when checking the oil. Also, make sure the crankcase is level when checking the oil.   

Loudpedal,

Tec's are with it screwed in, by my manual!!

I'm checking with the dipstick screwed in, on level ground in my garage. 

A Suzuki motorcycle I had previously liked to run with it's oil level just over the "add" mark, and I've been told this was a case for many Suzuki's.  Maybe this is the same for my blower. 

Also, when I clear some of the EOD stuff, I "run" the blower up the bank a bit which tilts the machine back on maybe a 25 or 30 degree angle.  I was thinking that possibly that might be the cause. Perhaps when run on this angle the engine spits out what it thinks is excess oil.   Unfortunatly, there has not been any snow in my neck of the woods for the past 2 weeks for me to run the blower to test my assumption. 

Thanks for the input guys, I'll post any findings. 

Yes, tilting could do it.

We have an olsd John Deere 1032.  I think it's a Tecumseh 10hp engine ... that's seen some really hard use. Anyway, the thing doesn't burn a drop of oil after I started maintaining it.

Suddenly the oil level was low, really low.  I found out my Dad had tilted it up when tackling some snowbank.  Sure enough, I found the oil slick outside on the sidewalk where he had done it ... as well as the breather hole in the  side of the block ... with a track of fresh oil still just below it.

I warned him about it, topped off the oil and the thing has been fine ever since.

You might want to look for a crankcase breather on the side of the block.
