My Craftsman lawn tractor's Briggs & Stratton 15hp engine smokes. I finally gave up and brought it to a repair shop. Their professional opinion is that it can't be repaired for less than replacing the engine.
Since it's a lost cause anyway...
What if I just filter the smoke and keep running it until it seizes? I can't think of any reason not to.
Can anyone think of a way for me to filter the smoke out of the exhaust?
Would a diesel particulate filter clean up the gas engine's smoke?
Is there such a thing as a cheap small DPF (probably for small diesel engines)?
I don't remember the ratio we used but I had a buddy whose tractor smoked pretty bad and we were able to help it some by taking a thick oil like 20w50 and thinning it out with some 2-stroke ashless oil.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
Come on Man, are you serious? Sounds like a waste of time.
If that is oil smoke, which it sounds like, then it's shot. You can have it bored out, put an oversize piston and rings in (probably valves and guides too), and so on, or use it until it physically doesn't run anymore, or junk it.
There are ways around shelling out the big bucks for a new engine. For example, I wrecked the 11HP B&S on a riding mower not too long ago. I hit the scrap yards and found a John Deere rider ready for crushing, that had an 11HP B&S in it, but it was stripped of it's carb and some other stuff. So what! My old engine has them! I got it for FREE and was VERY pleasantly surprised to find that long block to be a VERY low-hour block as the cylinder looked like new! Put it all together and that rider is now better than it has ever been in my ownership. Cost? I spent about $7 on gaskets.
If you have a trade school nearby that does automotive machining they might bore it out for you. I've had that done in the past too. Then all you're stuck with is the cost of parts.
Or there is scrounging around for a complete replacement engine. If you put yourself in the right place at the right time, they are free or nearly so.

Sounds like the corpulent fraulein might be doing her solo right about now for your engine. If you're going to need a new engine soonish anyway, I wouldn't bother nursing this one, unless you expect to come across a deal on one given more time.
