    yup

    that might be the vacuum leaks or the tune, though.

    I think I have a leak in the same place. Does it also cause you idle to be weird?

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

    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)

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

    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.

    ^^ 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.

    Nice I got that same muffler, although with a single 3" inlet. How deep does it fit into there? Does it hang super low under the car?

    Needs sound clip :D

    I've got some E36 springs sitting in a box somewhere that should accomplish the same. thank you, though!

    I've got good condition front IX springs and rear x3 springs (I think) that the PO had on my coupe. Provides proper 4x4 status -- the rear springs eliminate the IX rear end sag. PM if interested, I have to dig out of garage for picture. Shipping cost from NY + some very very reasonable amount.

    thanks! it's come a long way but definitely has a long way to go. I'll get a clip together - actually growing happier with how it sounds.



    off the top of my head, the current list of things that need to be addressed:

    urgent

    - motor has a top end rockery noise, needs a valve adjustment
    - exhaust leaks need to be addressed - aiming to take the midpipe down, grind down the welds and try to get any leaks closed up
    - exhaust hangs low due to flex joint and no support for midpipe, needs a hanger somewhere on the trans brace
    - motor burns a decent amount of oil and smells like it.. :[
    - leaner tune
    - DS front strut is stripped, needs to be replaced. I have a pair of bilsteins to go in, aiming to reinstall stock front iX springs at the same time for dat 4x4 stance


    soon

    - catback needs to be have its mounting ears straightened
    - rust hole next to muffler needs to be closed up with a patch plate
    - rust holes under taillights need to be treated with converter and sealed up
    - headlights are abysmal, need to be re-wired and probably replaced if I can't get the lenses to be clear again


    before the winter

    - aftermarket fogs + mount
    - mudflaps
    - tear down driver's seat, replace collapsed foam bolster with decent one
    - variety of cosmetic issues
    - rear valence needs repainted
    - tow bar needs removed, bumper and shocks replaced
    - rear suspension needs all the bushings tossed at it
    - rear calipers need to be rebuilt and painted
    - rear rotors need to be turned
    - rear brake lines need to be swapped for coated SS
    - diff needs to have its toasted VC swapped for a good one. might just swap in the full set of 3.91 diffs I have stashed.

    So once you've had enough your only buyers will be from out here. So keep us (me) posted.

    Really, this thing is radical. I love my ix coupe -- until a new post for this car pops up.

    Short driving clip after the tune, please.
