    Great find! I have a stock exhaust with known good cat that will pass smog. I was saving it to lend to NorCal folks who are having issues passing the sniff test either due to bad cats or due to having catless or race exhaust. Either way let me know if you need it.

      That's a very generous offer, thank you. I will definitely be in touch if I need to go that route.

    Some more progress over the past few days. I managed to liberate the center section, only had to cut one bolt! With it off the car I was able to admire the incredible welding work:



    Enhance!



    Hope you weren't eating. I don't know what it is with exhausts on these cars, when I got my DS car it also had an egregious fake dual exhaust tip. I have a bit of a puzzle to solve regarding the muffler joint, I purchased OE clamps but with the current configuration (center section piping nests inside muffler piping), the muffler pipe diameter is too large to work. Will have to brainstorm.



    After buying and trying two different tools, I managed to get the stock chain tensioner out and replace it with an S50 unit. The winning device ended up being a stubby adjustable wrench, a deep 32mm socket was too long and smacked all the A/C hoses and nonsense. Shout-out to the gorilla who installed this thing, I nearly broke my knuckle punching the block when it finally broke free.



    With that done, I reassembled everything affiliated with the valvetrain work and reinstalled the valve cover, so that half of the motor is done. My accessory drive belts were all tired and stretched-out, so I've replaced those. For the A/C belt I had to order a second one, the outgoing was 13x810mm but the replacement of same size was simply too tight. A 13x825mm is on the way. I noted that all of the associated bushings are clapped out, I picked up a few for the power steering pump to get my Pelican order over $100 and earn free shipping, the others I will get to in time. The P/S ones are the hardest to get to so I'll tackle those with the intake components out of the way.

    Other bits and bobs... swapped the weird Momo shifter that came with the car out for a BMW piece that originally came on my DS car. Swapped the door handles out with used good ones, as the ones on the car were painted body color.

    I am waiting to get my injectors back from VAC this week, and also for the intake blocks, when those arrive I can put everything back together.

      Injectors and intake blocks came in today, intake will go back together this weekend.

      VAC did a really nice job with the packaging and summary report.

        That looks like a supersprint resonator with the X pipe cut out and cat welded in. Ha!

          Was feeling under the weather this weekend, so unfortunately I didn't make as much progress as I hoped for on the car.



          Bought a huge O-ring assortment from BelMetric. Here are the generic O-ring sizes for the connector block between the throttle bodies:



          10.78 x 2.62mm (where did this sizing convention come from...?)



          I went to the local pick-n-pull to see if I could get some stock mirrors and a bit of A-pillar sheetmetal to help me with my rust situation. One car had been on the lot for about 10 days, the other for maybe 20.





          Both appear to have been rolled. There was absolutely nothing to be salvaged from these cars... mirrors long gone, A-pillars bent, everything of value absent. I have a feeling you need to be there day 1 when an e30 shows up in the yard. To avoid leaving empty-handed I scavenged various bolts and fasteners.

          Upon further thought I don't think normal e30 A-pillar sheetmetal is going to work for me (longer flange for windshield bonding), so if anyone reading has some M3 A-pillars or can point me in the right direction please let me know. In positive news, I have secured an M3 cowl from Markus in Germany that is somewhere between California and Germany.

            Pall, Might want / need to order the A pillar metal from Markus. Should have combined shipping with your cowl. #6 shows still available in the European market.

            Sorry guys, haven't touched the car in something like three weeks. Hoping to get it back into running shape this weekend if I can find the time. I have, though, managed to collect all the sheetmetal I should need around the windshield:

            M3 cowl - from Markus in Germany, a week before they were made available again in the US... dang
            E30 A-pillar outer LH - there is no M3-specific piece, but it's NLA, so I found one on eBay in Florida
            E30 A-pillar outer RH - also NLA, had to get this one from eBay in Cairo (!)
            M3 A-pillar inner LH - available and purchased new from dealer
            M3 A-pillar inner RH - NLA, so I purchased a standard E30 piece from the dealer. Fabricator will have to extend the flange manually.

            Hopefully I've got an update by the other side of this weekend.

              Sheetmetal has been assembled. As mentioned in my last post, the RH A-pillar inner is a standard E30 piece so the flange will need to be extended a few mm for correct windshield bonding surface.

              Having some trouble re-assembling my intake, the two castings are not keen to fit back together. It feels like the O-rings on the vacuum junction block are not finding "home" and seating as they should. I will try to massage it further, but if there are any obvious things that may be causing this please let me know.

                do you have the part numbers for those external A pillars? Can't seem to locate them on realoem.
                Did you confirm that it's the same part on all e30's?
                Sucks that they're so hard to find...

                  Just interested did the new cowl come with your chassi number stamped on it, I do recall that was what used to be the case when ordering one from BMW.
