N55 Aluminum Expansion Tank

rscott · 05-01-2019, 01:48 PM

My expansion tank has cracked as so many others have, and I would rather not go through the trouble of having to replace one every 2-3 years, but I can't find any aluminum expansion tanks for the N55, only the N54. Are there any plans for anyone to make one (doesn't seem too likely given how long the engine has been out now), or is it possible to modify one made for the N54 to work properly?

I would imagine the one for the N54 is only specifically for the N54 because of dimensions/fitment. Might not be too hard to make that one work.

Man I would love if there was an aluminum option. Mines cracked twice within 30k miles
