They told me that I had a long block issue. Or the head gasket is blown. I don’t think flushing it will correct that would it?

The only way to fix a blown head gasket is to remove the head and replace the gasket. What is this "long block issue"; can you provide more detail.

What is this "long block issue"; can you provide more detail.

Dealerships rarely replace head gaskets anymore, and most dislike the bother of all the parts transfer with a short block. Hence, they probably recommended a long block.

Did you ever figure out what the problem was?

Is it really “sludge” same issue 2015 Pathfinder only 47,000 miles and random white smoke puffs out for a few seconds then dissipates. Not just start up but anytime and not consistent. Nissan thought it was the catalytic converters and changed it but still it happens. My mr Janice can’t figure it out as the damn thing won’t do it when it in his shop and he’s been working on our cars for years, I totally trust him. Some posts say head gasket or rings issue, one forum even said a specific valve cover was to blame. I just bought this car...and I’m trying not to regret it as I love my platinum, it’s a great car but I’m thinking I might have to get rid of it and never buy a Nissan again. Please help me figure this out so I can keep my car ??????

I wish I knew. I was just told the only way to fix the it would be to get a new engine and that would cost me 11,500.

the dealership told me it was a long block repair which means that I need a new engine. 11,500. It is still under warranty but they will not cover it because they say that I did not maintain it and I did. 🤷‍♀️ My car still runs great, it is just pretty embarrassing when I start the car up. I am not fixing it and will just keep doing an oil change every 2 months until it stops working. Hopefully it will keep running ok. Everyone that asks about the car I make sure to tell them not to buy a Nissan and how bad the Customer service is.

That is terrible. I am having similar issues with my 2019 Pathfinder and a similar story...seems to run fine except the occasional white smoke out the back. They quoted me 17.5k for a new engine.

Hello, Showbox jiofi.local.html tplinklogin
New member here. I have a 2015 Nissan Murano that has sludge in the engine. It only have 51,000 miles. And yes, I changed the oil.... At every start up, I get BIG puffs of white smoke. I really like Nissan, as this is my second Nissan vehicle, but this sludge issue is changing my mind. Has anyone else had or have this problem. Everyone tells me to trade it in. Nissan says I need a new engine. Any suggestions or fix?

Hi and welcome!

Hi and welcome!

Puffs of white smoke during startup can be caused by some of the following:

• Water condensation in the exhaust pipe especially during a cold start.
• A small breach in the head gasket. This generally requires replacing the head gasket.
• One or more leaking fuel injectors which causes an overly rich mixture. Run some good injection cleaner, like BG products 44K, through the system; give the cleaner about a week or two to do it's job. Otherwise replace all the fuel injectors.

Looks like this is common. I just had my 2018 towed into the dealership . It only has 31,000 and white smoke is coming out of the tailpipes. I was given the same excuse most of you posted. They tried to say it was lack of maintenance on my end (not true) and I need a new engine at a whopping 15,000 … we filed a complaint. That’s so crazy these Nissans are having thus problem.

Hi Denise, welcome to NissanForums. Sorry to hear of your predicament. Have someone other then a Nissan dealer remove the valve cover from the engine; if there's no evidence of sludge, then here's several possible causes:

Puffs of white smoke during startup can be caused by some of the following:

• Water condensation in the exhaust pipe especially during a cold start.
• A small breach in the head gasket. This generally requires replacing the head gasket.
