330d Timing Chain Replacement
Discussion
F30 (2014) 330d requires timing chain, noisy at start up.
Had since new, 200k on it with no issues to date other than regular maintenance.
Never changed the gearbox oil, was always reluctant to open up (rightly or wrongly).
Plan will be to keep car and hopefully put another 100k on it.
What additional work should I be looking at with the engine / gearbox dropped out ?

Instead of asking on here - speak to a well known & respected specialist that deals with these day in, day out - https://www.adcbmw.uk/ - they'll be able to tell you all that's needed / recommendedHad since new, 200k on it with no issues to date other than regular maintenance.

Never used them myself but know quite a few that have and they've had superb work done and back to them very quickly

Pilot bearing? Confirm rear main seal not leaking?
Clutch and shifter bushings if it's a manual?

Someone else who spells it correctly.
It's not guibo, gweebow. It's giubo, joo-bo.
Repairs? Engine mounts etc. Otherwise, fix as it needs it. If you can get 300k from it, you've done well.

Incidentally, many F30s went away from an aluminium giubo at LCI in order to ease the vibration loads on the transfer box splines (X drive) might be worth a look into.
I would also have suspension bushes checked
200K, impressive.
I know of a couple of airport run 330ds that have done more than 300K on original chains, engines, gearboxes etc.
Just get the chain done and be done. There's a massive list of "Whilst you're in there" stuff you can check, but I would only do stuff that is very obviously in need of replacement.
Depending where you are, BMMinitech in Colchester, Essex, are specialists in chain replacement and can often turn it around in a day. A lot of people travel from all over the country for that service.

North Scotland, local garage will be carrying out the work, not near any BMW specialists apart from BMW who I will not be using

Ah OK, you're all the way up there!North Scotland, local garage will be carrying out the work, not near any BMW specialists apart from BMW who I will not be using

First thing I would do is ascertain if the chain gear actually needs replacing first.
Your local garage can use this tool to determine if the upper chain (the one that wears out) is too slack - https://www.ebay.co.uk/itm/386152004162
If the chain is in spec, it's likely just the upper tensioner has failed and taking too long to fill with oil during startup. It's been revised a couple of times over the years.
That will be a £150 fix inc the measurement tool vs £1000 ish.
If the chains do indeed need doing, only use genuine or the IWIS aftermarket kit, and be sure to replace the chain oil squirters as well as they tend to block up with soot.

Thanks, looks as though will require new chain, will be using BMW parts and ensure they replace the chain oil squirters.First thing I would do is ascertain if the chain gear actually needs replacing first.

Depending on where they're sourcing the parts from (local dealer?), Sytner Stevenage is worth a look for parts. Very good website and prices seem to be a fraction lower than I have been quoted by my local dealer etc.Can add up if theres a few big-ticket components on the list.
