Turbo Oil Leak B57!

[Tom D]

What was your outcome Tom?

Fixed under warranty, I read online that some BMW's had the same issue, Looking at the hose it leaks from where the rubber section meets the steel pipe, it's hydraulically crimped on, either there's insufficient crimp pressure or too much and its cracking the steel. I noticed the replacement part had slightly different rubber hose. I guess they have rectified it.

Putting this out there since it sounds like it's not a Ineos design/part mistake but BMW engine issue. I will add on my B58, I had a hose that was leaking coolant. 2400km on the clock. I wonder if BMW has a hose supplier issue.

Looks like I have a similar issue, but from where the top oil hose connects to the turbo. No warning lights as such, just some smoke coming out through the headlights when I pull up at lights etc, and then on inspection I can see oil running down the side of the turbo, which looks to have come from the top hose. Have booked in to local Ineos dealer for them to take a look at. I am always concerned if they have to order parts and the inevitable delay that follows.

Thats exactly the same as mine.

Sorry to hear that.

Mine is still out of action while they ‘investigate’. Meaning, it’s sitting in the corner of their yard

Here is a wild out there theory without any fact…not to be taken seriously, though I do now wonder.

During the PTO2 test drives we were not allowed to see under the hood in the engine bay. Was there really a BMW engine (B57 or B58) in there? They were quite fanatical about the ‘no look in there’ at the time.

As there are way to many issues with hoses, fluid levels for any sort of solid testing to have been done.

As I mentioned, just a wild thought.

In 12/2021 I had two PTO2 in my garage and during the international automobile fair in Munich was a PTO2 on display and one was running as a "taxi". All had BMW engines inside, but with reduced power as the transfer case wasn't able to cope with the power at that time. There were around 120 PTO2 build, each (batch of) car(s) for a different purpose (the ones which were in my garage had a stupid suspension design at that time, but their purpose was to show the look of the car, the body, the interieur etc. Their purpose was not to show the driving capabilities (and the suspension setup has been changed). So maybe other engines were tested, but I don't think that such cars would have been shown anywhere to the public.

It looks like it's a common issue. From reddit. Here is the response of the BMWAI I created (still in beta). Its trained on other peoples responses on similar problems. Feel free to ask it more questions - [https://bmw-ai-ten.vercel.app/](https://bmw-ai-ten.vercel.app/)

Based on similar questions discussed by BMW owners:

It seems like you may be experiencing a turbo oil leak issue, which is not uncommon with the B58 engine. Several users recommended checking the turbo seals, boost pipes, and the connections for any signs of oil leaks. The oil around the turbo/boost pipe areas could indicate a problem with the turbo or the connections leading to it.

A common solution mentioned was to thoroughly clean the affected areas, monitor the oil levels closely, and check for any recurring oil leaks. If the oil persists, it may be necessary to inspect the turbo seals and connections more closely for any signs of damage or wear.

While some users suggested that a slight amount of oil around the turbo area can be normal, excessive oil leakage or burning could indicate a more serious issue that needs to be addressed. Keep an eye on the oil levels and any visible signs of leakage, especially after driving the car hard or under boost.

According to BMW Enthusiasts on this topic, turbo oil leaks can sometimes be challenging to diagnose accurately, and it may be beneficial to have a professional mechanic inspect the turbo and related components for any potential issues. If the oil consumption persists, further investigation may be necessary to prevent any long-term damage to the engine.

If you notice any additional symptoms or changes in performance, such as excessive smoke, rough idle, or loss of power, be sure to mention those details as they could provide more clues to the underlying issue.

Like many of us on this forum, I've owned a 2015 BMW 335i. My turbo blew at 70k miles. My plan with Grenadier is around 50, swap out the turbo for a metal one and replace the respected hoses with metal pipes.
