I have a 2015 New Holland L230. A few weeks ago, it made some sort of noise, which I didn't witness and white smoke blew out the exhaust. A mechanic felt around inside the turbo and was satisfied that there wasn't a problem with it since there also was not excessive oil in the surrounding hoses. It was a little low on coolant, but the oil was and is not milky. So, we've been using it for a few weeks with no problems until a couple of days ago. It began blowing black smoke and used a quart or more of oil in just a couple of hours or less (if I can trust that Marco checked the oil that morning and it was at the top of the hash marks.) I read that the air filter being clogged could cause that, but it isn't more than a month old. I'll have the mechanic back to check it out if it continues to happen, which I assume it will, but I wanted to get some opinions. Thanks.
