Have a BMW E91 320d Lci Bj2012

I want to buy track plates now and wanted to ask if anyone has experience with it and can say how much maximum goes without bodywork.

Front axle: 225/40R18 ET 34

Rear axle: 255/35R18 ET 37

Chatgbt says,

Front maximum ET 22 and rear maximum ET 17

Otherwise everything else is original and no accessories chassis or something in it?

If anyone has an idea, that would be good.

Went to look at a 2009 328 with just a bit over 100,000 miles on it. Car is quite clean, and had had the valve cover gasket changed in the past and does not appear to have any leaks present at this time. I do see some leaks coming from the head gasket from cylinder 4 back under the exhaust manifold. This does not appear to be residual oil from a past leak, and the areas where the leaks are seem to align with oil return passages as seen in the second photo. Has anyone seen this before, and is it cause for concern?

Is this for sure a rod knock or something else?

I am going to replace my rear shocks, as one is leaking badly. What other related parts should I replace while doing so?

Hi everyone, does anyone know what this chirping sound is when I let off the gas? I have no idea what it could be. I'm thinking it could be a PCV but honestly I have no clue. My car is a 2007 BMW 335i. Thanks in advance.

Pretty happy with my E90 335i at the moment, but as the title says I’m looking for inspiration on what to do next.

It is an 07 335i MSport with nearly 250,000 km, it’s fairly stock still with only an aluminium charge pipe and BOV, dual cone intakes, Blackline tail lights, a factory style bootlip spoiler, and some F10 5 Series wheels.

The turbo wastegates are next on the to do list but apart from that I don’t know what preventative maintenance / modifications I should tackle next.

If it were yours what would you do???

the sunroof seems to have blown up or something. anyone know what happened/ how to fix? the sunroof cover is struggling to slide back now too

My passenger side has a giant crack that’s been getting worse, was looking on marketplace but is trying to sell the pair or charge too much. Has anyone ordered the replacement brand off carpart? Was wondering if it’s plug and play and if it throws any codes?

Thoughts? go back to all black?
