B&S 1150 Snow series problem

I'm sure I've read about this problem before? Maybe it was on the Tractor Forum? Anyway, a search didn't find it.

Fired up my Deluxe 24 Platinum yesterday - it always starts first or second pull, very impressive!
After about thirty minutes of blowing the engine started making a grinding noise and losing power - I shut it off immediately.
Pulled the plug and poured Seafoam in the hole - just in case. Couldn't pull the engine over with the rope, tried electric start - nada!
Pulled the dipstick, nothing showing, so I drained the oil (very easy on this engine) - not much came out, what did was 'silvery'. Put fresh oil in and started looking for the problem. Noticed a slick on the right side, beneath the engine. Closer inspection showed that the 'oil filler' cap on the right side had come undone and puked oil out, tightened it as much as I dared. Removed the belt cover and managed to turn the engine over with a breaker bar and socket on the pulley bolt. Cranked it over with the electric starter to remove the Seafoam, replaced the plug and it fired up without any bad noises.
Since this happened, doesn't seem to have lost any power but the exhaust has an oily smell now, I'm checking these plugs and the oil level daily. Is there some way of ensuring these caps don't loosen? Does Loctite work on nylon?

Thanks for your patience.

Slide a fresh o-ring on there, and snug it up real good... use a tool if you have to, > finger power.

If you still have the old oil, you can send it out for testing. Is this thing under warrantee? "SILVERY" oil isn't a good sign.

Their usually a tapered thread, but you be careful not to over tighten. I would use Loctite blue. or some kind of thread sealant would be preferable.

You might try safety wiring the cap.

This is a plastic cap. It's generally not a good idea to use liquid threadlock on plastic, it can degrade some plastics. If you really wanted to do that, I'd try it on a spare cap first, but I'm not really comfortable with the idea. Worst-case, the plastic starts to come apart, dropping into the oil, and then maybe the cap comes off anyhow.

The plastic oil caps that I've used are typically a straight thread, with an o-ring under the cap. As you tighten them, you compress the o-ring. Is that the style used here? Is there an o-ring under both caps?

I like the safety wire idea, if there was a practical way to do that. They shouldn't loosen in the first place, of course, so you shouldn't actually need a safety wire. Hopefully it just wasn't fully tightened last time.

One thing you can do to make them easier to monitor is clean up the caps, and make a line from the cap, to the engine block. With a Sharpie, or similar. Now you can see at a glance if the lines are still lined-up, meaning nothing's moved, or if something has started to loosen. You can still check it by feel if you'd like, but you'd have another easy way to check at a glance.

I'd change the oil one more time, right after running it, to help flush out any remaining shiny stuff in the oil. Doing it right after shutting it down will have more of that stuff suspended in the oil, and therefore more likely to drain out.

Oil fill caps falling off are not an inherent design flaw and no thread locker needed. Properly tighten it when installing. Looks like someone broke a nub off the one that didn't fall off and might have gotten a little shy on the other.

This is starting to look like a common problem.

Please direct all snow blower questions to the forums and not to me with PMs.

Thank you all for the fast replies.

The plugs don't use o-rings, though that may be a good fix. I like the wiring idea and will look into it.
The 'tabs' on the plugs are of a ramp design, you can tighten them but they can't be easily undone - though I took this one out with my fingers after tightening it this morning - after changing the oil for the third time. Maybe I can find a replacement in metal with a hex head?
I will take this engine apart in the Spring to see if there is damage to the crank/piston/rings.

Thanks again.

tighten those by putting a screwdriver across the nubs and turning.

I'd be far more concerned about the silvery oil than if the plug stays in.
