I am replacing my turbos soon. What else should I fix?

Lambobimmer · 09-19-2015, 06:40 PM

I have 49k on my 2009 Z4 and I am wondering if I should replace the water pump while I have the turbos out.

Anything else?

Stock or aftermarket. Kinda silly question as aftermarket are same price but way better but maybe it's warranty work.

Do the pump and tstat. oil pan gasket is also a good idea. and if you really wanna get the most out of the job, thrust arm bushings and motor mounts.

What is the normal life for the pan gasket?

Haven't been able to pinpoint that.. My wifes 2014 x1 with the n55 (28k) has a slight oil pan gasket leak but my old e92 had 120k and was still on its original one and wasn't leaking.

Walnut blast. Do any other upgrades then too. Tuning, pipes, intercooler, etc.

Sorry, I meant maintenance items. I am FBO except for inlets, which I will install at the same time.

I am really wondering if there are maintenance items that I should consider doing while I have the subframe and turbos removed. I think that I will do the thermostat and water pump but I will hold off on the oil pan gasket and I will inspect the engine mounts. Any other items I should consider?

In addition to water pump and thermostat also consider replacing oil filter housing gasket and valve cover gasket. Cheap insurance to avoid problems later. Props for doing the work yourself.

oil and coolant lines for said turbos would be cheap insurance

The pan should start leaking at arpund 100 or so. Mine started seeping at 90k on my 07 335, just got it fixed at 120k. Fresh motor mounts and upgraded trans mounts are very easy also and will tighten things up
