    ^^ It fits reasonably well into, uh, where the cat would normally go. the IE long tube collectors are lower than it.

    Managed to knock out some motor diagnostics in the last few days. Overall, a lot of indicators are pointing to it desperately needing a proper tune to continue diagnosing. I hope the rings aren't fucked, and I hope I didn't get bent over on a theoretically nicely-build bimmerheads motor. (I did buy it briefly-used)


    - I adjusted the valves in hopes of making the motor less clattery. Even though a lot of the valves were very out of spec, putting them right sadly did not improve the racket significantly.

    - I installed a catch can in an effort to understand why the motor is burning oil. If it's aerating the oil in the pan, a lot of it will come out in crankcase gases and should be measurable in the catch can. If not, ????

    - I did a comp test and came up with consistent numbers, roughly 150-155, which is in line with the expected piston compression. Did not do a wet test, aiming to get a leakdown together this coming weekend.

    - I did a vacuum test and it ended up at around ~12-14 at idle, which is low, and probably related to the motor's shitty, stumbly idle. Unclear if it's a cause or effect, though. Going to smoke test this coming weekend to rule out intake leaks.

    - After a lot of whining and resistance on my part, Julien convinced me that it would ride better with proper front springs, so we installed OE IX springs I've been stashing and replaced both front struts at the same time with relatively fresh Bilstein HDs. The struts that came out (that the seller of the car claimed were replaced in 2014) were Bilsteins that said MADE IN WESTERN GERMANY on them, so, par for the course.

    new ride height is appropriately 4x4 -




    I've got some new dampers and springs for the rear that need to go on, as it's pretty saggy. Soon.

      also if anyone is out here reading this and has a DS rear bumper and some bumper shocks, I will trade you straight across for the entire tow hitch setup. Please. I hate it.

        The intricacies of the IX. I am pretty positive my struts and springs are Western Germany.

          the crazy thing is someone bought and installed aftermarket struts into this 1989 model year car, before october 1990!

          (and also that they've actually retained some life for 29 years)

            I didn't know Bilstein also made struts for the iX.. could you take a picture of them? Or do they look like the OEM ones?

              Mine are Bilstein struts from Western Germany. I can take a picture later tonight.
