Merry Christmas, I hope you are all festively plump!!
First an apology, I'm aware there's a huge thread on the R56 death rattle and I know some of the questions I'm going to ask are answered on here somewhere, but I've just spent a good couple of hours trawling the various threads and I've not managed to remind the info. I thought it might be a good idea to ask some of the common questions on a quick single page post for everyone's future reference.
My situation is similar to others. Just took on a 70k MCS 2007 which has gone from a quiet engine to sounding like a tractor from cold in the 700 miles I have put on it. I know the tensioner was changed at just under 48k from the service history but I'm not sure what was fitted.
I understand the tensioner pushes a little harder once oil pressure is up, which is why the noise goes away (right?) How safe is it to drive the vehicle with this issue? Will the chain be likely to jump as much when cold as after its warmed up and there's more pressure on the tensioner?
Mini fitted tensioner 11317607551 at 47,900 miles, is this the uprated/longer tensioner part? If not, can someone confirm the part number? (I've come across 3 this afternoon) There seems to be a lot of different numbers on various threads. Is the 2011+ model tensioner the same version? Is that the "latest" tensioner or is it a different part altogether and irrelevant.
Does anyone know the cost of a chain/tensioner/guide/ full replacement and is it a mini only job, or can a reliable Indy do it?
Finally, could I be hearing these noises because I live on a hill and park with the bonnet lower than the boot causing the oil to pool at the front of the sump? The noise goes away pretty quickly when I've driven the car a few hundred yards. Is it possible I don't have the death rattle at all, just a noisy DI engine that's a bit oil hungry first thing?
I look forward to hearing back from the forum guru's, happy new year to you all too.
