Oil (whether nicely smoothed or burnt) out the tail pipe would count towards HC - which has been a fail since emissions started being testing.
Who's talking about a fail? They have the right to stop you driving the car away.Here's a clue, they can't stop you driving it away - even if it fails badly.

I have a 125i coupe of the same era. Hope this is not common on those
Not if its the nice 6 cylinder petrol 3.0 125i then nothing to worry about should be fine to over 200k without any chain problems.Its the cheap and crap 4 cylinder ones with plastic components that should have been metal, N47 and N43 engine code post 2007.

Hope so. The MOT man now days has the powers to impound your car if too much oil is coming out of the back. They have not a single thing to say for oil coming out at the font like mine. Some of you are at far greater risk than I in getting into trouble because you don't know where your oil has gone.
You sound like a right spacker. Please, stay off the internet.hooblah said:

So when you said it doesn't stretch, we agree that it does, you just object to the use of the word.
And if they were to measure the elongation of the chain, the plastic deformation is exactly what they'd be measuring.
No, look I am not going to argue the point. And if they were to measure the elongation of the chain, the plastic deformation is exactly what they'd be measuring.
Have a look at a generic procedure to measure chain elongation and make up your mind. Once you look at the procedure I am fairly sure you'll see it is wear between the pin and bushing that is being gauged.

Correct. It wears, it doesn't stretch. it just gets called stretch to confuse. Have a look at a generic procedure to measure chain elongation and make up your mind. Once you look at the procedure I am fairly sure you'll see it is wear between the pin and bushing that is being gauged.

4 and 6 cylinder N Series engines use virtually the same chain components. The 6 cyl runs more smoothly so are easier on the chain but they still wear.Its the cheap and crap 4 cylinder ones with plastic components that should have been metal, N47 and N43 engine code post 2007.
The N47 problem was insufficient lubrication to the upper chain. BMW have revised this, and the rollers in the upper chain (and the other now I believe) now have oil holes in them.

Don't let that trolling tt see this! He'll be out there with his Black and Decker attacking the chain! All those bits of swarf from drilling the holes will also help with the smooth running of the engine floating around in that vintage oil.......The N47 problem was insufficient lubrication to the upper chain.

Ugghh, cheap and nasty split rollers.The N47 problem was insufficient lubrication to the upper chain. BMW have revised this, and the rollers in the upper chain (and the other now I believe) now have oil holes in them.
