236,600km Gave the garage a good reshuffle and cleared out enough space to roll the car in for some wrenching. Was nearly due an oil change so used it as a chance to knock out a few bigger and smaller jobs. Last I changed oil was only in October but already managed to clock up 7k km's so figured it was time. Had tried doing some data logging a while ago and noticed the long term fuel trims sitting at 8.5%. Not enough to cause any noticeable rough running or trigger engine codes but did seem a tad high. Followed @Harper's lead and got myself a little smoke tester. Was tossing up getting one of the higher end models with pressure gauges and other bells and whistles but in the end figured it's a tool that would only ever get occasional use so went with the cheapest one. Also got the inflatable bladder adapter to go with the kit that plugs into the intake boot. Nifty little setup, the tin can solution felt almost humorous but works well enough. The device produces a decent amount of smoke but didn't reveal any vacuum leaks so the issue must lie elsewhere. Will clear adaptations and continue keeping an eye on data logs. At some point I was also getting codes claiming the ICV to be stuck open so tried switching that out as well. Picked up a spare one from Pick-A-Part, gave it a good clean with throttle body cleaner spray, compressed air and lubed up the internals with a bit of oil. The unit that came out still seemed to move freely enough but will see if the codes come back. Drained the oil which didn't look too bad but there was quite a bit of metallic sludge stuck to the magnetic drain plug. Still only 9k km since the engine rebuild but already the 4th oil change so not entirely sure at what point it becomes something to be seriously concerned about. Will do another oil change in 4-5k km's time and reassess. Video The biggest mission I decided to tackle this time around was replacing the oil non-return valve that sits in the oil filter housing. First saw it done in one of M539's videos and with the vendor seemingly not shipping to New Zealand, I took the chance to pick up a couple of those valves whilst over in Europe last year. Finally gathered enough motivation to install it after stumbling upon a thread on E46 Fanatics of it supposedly fixing the guy's startup engine tick and low oil pressure issue. Was mentally prepared for oil to start splashing out all over the place when removing the housing but the mess ended up being almost underwhelming. The valve is press fit into the housing and its extraction needed some tedious prying out with a screwdriver. I used an old plastic trim removal tool as a sacrificial layer to protect the surrounding edges. Worked pretty well and managed to get the old valve out with little to no damage. The old valve didn't look too bad, the groove was barely worn into the side but the plug did seem to move quite freely in there. Poured a bit of oil over top and it drained right through. Tested the new one with brake cleaner and none leaked past. One weird thing with the new valve was that it just dropped into the opening without the need to hammer it in. Still snug enough in there that it didn't move around but loose enough that you could lift back out with just your fingers. Measured the diameter of the two with a digital vernier - the old valve was 25.07mm whilst the new one 25.01mm. Not a huge difference but still. Not like it has any space to fall out and I guess it'll properly mate itself to the surrounding housing after a few heat cycles. Jumping forward a bit, unfortunately it wasn't the culprit of my niggling startup rattle and the issue still persists. I'm beginning to think it not to be engine-related entirely but something to do with the gearbox/flywheel. Very hard to tell by the sound alone, near on impossible to capture it on video/audio and the list of potential suspects is ever decreasing. Regardless, still glad I replaced the valve. To finish up under the hood, I did a compression test just to check the general health of the engine. First time doing it since the engine rebuild so was a bit nervous but the results were pretty satisfying with all cylinders sitting at 200-208 PSI. Couldn't be happier with that. Finally, after hitting my head a few too many times on the boot door that wouldn't raise itself all the way up anymore, I got around to replacing the crusty old boot struts that were starting to become audibly annoying as well. Otherwise, she's sitting fairly pretty. The next bigger undertaking will be to finally wire up the reversing camera (thanks to @adro for the motivation), along with the boot elephant trunk repair and fixing all the broken tabs on the boot trims.

Don't have any leads on the batteries themselves but I've got a scanner that should be capable of coding it. Shout out if you run into trouble, I'm also Chch based.

It very well could be as simple as the battery needing replacing. E60-era cars are notoriously capricious when it come to battery voltages, many modules and sensors tend to go haywire when the battery isn't holding enough power. With your symptoms seemingly being all over the place, I'd suspect it to be the culprit. Worth replacing before going any further anyway. Keep in mind you might need to register the new battery to the car, especially if the new battery isn't exactly the same spec. The scanner you bought might very well be capable of doing it, just dig through the options on it.

How severe is the rubbing? If it's just slight then going to 225's should be enough. 235 at the front does seem a bit excessive for a stock setup. The shocks must be well gone if it's bottoming out that easily. A suspension refresh is well worth taking on if you're planning on keeping the car for any decent length of time.

Ahh man, well done! What a wee weapon. Looks so good in white, and the ride height looks absolutely bang on. Keen to hear how you go with the exhaust, looking to add a bit of sound to mine at some point as well. Was just clearing out the garage yesterday and stumbled upon a spare air intake scoop thingy. Was gonna go in the bin but happy to send it your way to save the scrap yard trip. Also have a few spare steering wheel button panels if you wanted cruise & media controls. Where'd you get those shifter & handbrake boots from? Hardly see any RHD ones around, or was it a DIY effort?

Personally, I just rubbed off the rubbery gunk to expose the bare plastic and left it at that. Have just been putting on some protectant a couple of times a year (Aerospace 303). Looks nice and matte, a few years in and don't really see the benefit of putting on some coats of paint.

Guy selling it is a mate of a mate, have seen the car a few times. A few imperfections here & there but plenty of car for the money. Happy to make contact and check it out more thoroughly for you.

Yes. Until I've saved up enough to buy it in 10 years time... Gorgeous machine. Glws but you should probably keep it.

Hey, at least you still have a physical dipstick by the sounds of it. They seem to be replacing those with just an electronic sensor nonsense on all the newer cars nowadays...

Weird one. If leaking from between engine and transmission then the most obvious source would be the rear main seal, although normally it would be a pretty slow drip. Are you sure it's engine oil and not ATF? Not sure of what the industry standard would be on that. If it were my car then I would have done the rear main seal preventatively as it's quite an easy job with the engine out of the car but an absolute pain if not. I guess at the very least would have expected them to inspect it prior to install and advise to replace if found to be weeping. Then again they might have damaged something during the install, who knows... Weirdly enough, a colleague of mine has a 116i of the same chassis. Last year the engine gave up with apparent loss of compression. Replacement engine got put in under mechanical insurance, a few weeks later engine starts to overheat, gets taken back to mechanic, deemed to be a loose coolant pipe. Eerily similar story to yours, wonder if there's some common coolant pipe that's a pain to install or something...

Yeah I've heard of that. Apparently you have to pretend to be a Timaru local though? Good news on the Rolleston fella, hope it takes off, the Chch fellas are long overdue a kick up the ass.

Just checked again, and she's live! Will get a WoF booked in. Hallelujah!

Yeah will give them feedback regardless whether it gets resolved this week or not, would expect much better with the amount of money you're shelling out. It's a tricky one as the next closest certifier is all the way in Timaru so really wouldn't want to go on a full on war path and end up in the guy's bad books if I ever need stuff certified again...

Bummer but hopefully it's something simple. Did you clear adaptations at all? Sometimes it will take a wee while for the DME to adjust to a "new normal" and it will be a bit erratic until the first proper drive. Have you checked codes? I've had a code for "idle control valve stuck open" so could be something like that. What sort of smoke tester did you go for? Recently did a bit of logging and found Long Term Fuel Trims sitting at 8.5% so am looking to get one as well. Have heard good things about the AutoLine Pro range, supposedly comes with free shipping through Amazon so leaning towards that but keen to hear what you've found.

Not per se. The typical stuff like has to be garaged while not in use and assumed up to 10k km's a year. Not sure how that's policed though. The tag is on the car and have the paperwork/receipt from the certifier saying that it's passed inspection but doesn't say what it's certified for though. Wasn't enough for the WoF guy. I've still been driving it on occasion with the paperwork on board. I'd probably be able to reason with a police officer if I were to be pulled over, don't think it'd be as straight forward if I were to make an insurance claim though...

Not much to report on as far as the car itself goes, just some battles on the bureaucracy front. Had a valuation report done through NZVV. Came out to my place, took some pictures and had a chat, gave me a rundown on the mechanics behind how the valuation shakes out. Settled on $15k. Would have liked it to be higher but probably about right as to the market value if I were to sell it today. Main thing is that the higher the agreed value, the less likely it is to be written off in a fender bender. Forwarded the report on to Classic Cover who came back with a quote that I snapped up straight away. $15,000 agreed value, $570 yearly premium, $250 excess. That compared to the spit-in-the-face renewal letter I got from AA... $5,800 agreed value, $960 yearly premium, $500 excess. Make that make sense. Getting pretty annoyed with the certifier as the cert tag still hasn't gone live. The old WoF has now run out and I can't get a new one until the tag shows up online so the car is out of action. Been chasing the guy up repeatedly but he keeps on blowing smoke up my ass. First he said he'd upload the data to the LVVTA database the day of the cert but said it's unlikely to get approved until middle of January due to Christmas closures and all. Chased him up 2 weeks ago and he claimed it'd be live later that week. It wasn't. Called up LVVTA directly to check the status only to find out there's still no records for my car in the system so the certifier still hasn't submitted anything. Chased him up again on Wednesday, got told that it's "up for processing" on Thursday and should be live on Friday. Sure enough, still nothing. Not sure if this is just misleading anymore, starting to veer into the straight up lying territory from the guy. Will give it another week and might just show up in person. Getting pretty ridiculous at this point. Have read reports of tags going live the day of the inspection with other certifiers, unfortunately here in Christchurch it's pretty much a monopoly and the dude can just get away with taking your money and then dragging his feet forever. A mate had to wait 4 months from the date of inspection to his tag going live. I don't intend on waiting that long sitting down. But hey, at least I didn't have to get driveshaft hoops...

Bit off topic but have been curious on this for a while. Is there a reason people are opting for M52 conversions as opposed to M54? Have a mate that just got his E30 certified with an M52B28 and have heard of a few others too. I would have thought the M54 to be, I guess, a superior engine, the fabrication involved and fitment would be pretty much the same and M54's are surely more easily available nowadays. Is it the electronics behind it that are more complex or just down to what people have had available to them at the time?

Ohh man that's epic! Looks so clean, what an absolute weapon it will be

AA has an upper limit on what you can set without having to go through the hassle of contacting them directly. In my case it was $8,350 with a yearly premium of $1,040. Just played around with the calculator on the MAS website @Hazzy mentioned and there didn't seem to be an upper limit, not for getting a quote anyway. Put in $15,000 for shits and giggles and the yearly premium came out to $980... In conclusion, f**k AA.

What happened to having too many cars?

The premiums going up isn't the shocking part. The fact that they at the same time devalued the car by that much as well is an absolute pisstake though.

AA Insurance. With them for 5 years, only claim I've ever had was a chip in the windscreen 3 years ago that didn't even need a full replacement. Policy renewal documents dropped in the inbox. Yearly premium goes up by $100 whilst dropping the agreed value of the car down to $5.8k, a drop of 23%. Nevermind the excessive maintenance and modifications, go find any 6-cylinder E46 Touring for any sort of money, let alone sub $6k. Getting the car evaluated in the next few weeks and going with someone else. Useless pricks.

Shouldn't be much, I'll package it up and get a quote tomorrow. Will send you a PM

More money than sense. X2 M35i xDrive... f**k off.
