LX3310 Exhaust Smell

LX3310 Exhaust Smell, Eyes and Sinus Burn

Anyone with a new LX3310 have an issue with exhaust smell? I’ve been around diesels my entire life (65 years old) and never had an issue with exhaust smell. The exhaust from my tractor burns my eyes and sinuses. It is not engine temperature dependent, it occurs immediately upon start up and continues the entire time running. While the tractor only has a few hours on it, I go out and run it for 10 minutes, come in and my sinuses are burning. It’s not like a normal diesel smell, it’s very acrid and is immediately bothersome. I thought perhaps it takes time for the DPF to burn in, or burn a coating off or something, but again this starts when immediately starting a cold engine and remains the entire running time. The selling dealer filled the tank. ?? Thanks

I don't know what Kubota is doing with their newest diesels but many road vehicles have a fluid that is injected separately from the diesel to reduce pollution. Your tractor may use that fluid. You can ask your dealer.

No, it does not use DEF, it runs a DPF.. the exhaust literally burns my eyes and sinuses. Not at all like my BX which had a regular diesel tractor exhaust smell.,,,,,

I just bought a new L3301 - had considered the LX3310, ultimately decided I wanted the larger frame size. The exhaust certainly smells different than my old 2003 New Holland. I haven't noticed it burning my nose yet - I just turned over 17 hours, but certainly a different smell than I'm used to. I had over 2500 hours on the New Holland.

How many hours?

Could it simply be paint, oil and manufacturing chemicals burning off of the exhaust system?

None of my Kubotas produce any noticeable exhaust odor and two have emissions systems similar to that on your 3310.

7 hours, I just went out and started it, completely cold, and I can immediately smell it, it's like eye watering and sinus burning. The exhaust pipe and DPF are completely cold so it's not like it's burning a coating off the exhaust. As weird as this sounds, I've always kinda liked the smell of diesel exhaust, this is completely different. .

The new engines smell different.....

Only 7 hours? Have you run it hard yet? With DPF you need to get that thing up to full temp and that means work'in it.

unfortunately the for engines do not have any real old diesel smell. Just like the new trucks

Anti freeze in the cylinder(s)?

Yes, it happens.

The new engines definitely smell different. Whether it's worse or better depends on your senses I suppose. If you're around diesel equipment long enough you can become a real connoisseur.

 

[Peter 315]

There's a real big difference , old vs new My old dump truck puffs black smoke every gear ,the new one not one puff the exhaust pipe looks brand new .......

Good point as it makes your eyes water and sinus burns.

 

[s219]

If there is enough antifreeze in the cylinders to cause that smell, it should be obvious looking at the reservoir level dropping over time. I'd also check the oil and look for that cream+coffee appearance. Together those would all be clues.

Welcome to the world of Tier 4 diesel engines. Obviously, you are sensitive to the smell of oxidized exhaust. I suggest getting rid of your new steed and buying a used Pre 4 emissions diesel. Only way to get around the non stink, stink.

Me, I'll never buy a T4 compliant diesel. The whole emissions thing with diesel engines is a joke in my view.

I have a sweet odor from my 1988 B2150 4 cyl Kubota. It does not show up until the machine is warm and been under load for a while. Really "pleasant" rather than irritating but also peculiar. Has gone on for MANY years and not related to antifreeze overflow or getting into cylinders. Yours has the smell immediately so obviously a different mechanism.

As for your 3310, I think your best solution is to reroute the exhaust pipe which is relatively inexpensive and a permanent solution. My larger Massey 2660 is a low profile and routes exhaust out under the rear, very similar to the old 1950's Fords and Fergusons.

88 is no emissions hardware at all. Just a road draft tube and you may be smelling hot lube oil. Mine do that, especially just after an oil change.

Hi, thanks, It's not coolant, the level has not changed and I've encountered that issue before. What's odd is that it happens immediately even on a cold engine. The exhaust pipe is not even warm. Start up after sitting 24 hours, immediate smell then as long as it runs. Hopefully it will get better over time. thanks

Agreed, but 7 hours?

Probably not.

It does not take much.

I see no evidence of a head gasket failure or coolant being burned. Hopefully it will get better over time.
