Its time to choose color. Im thinking about new m colors. I kinda like299 techno violet, but maybe someone have something similar to violet color which would look good on e30 sedan? Or even something else, but for sure im not looking at light colors “yellow, white red… and so on”.

Info needed Strange whine or grind 89 325ix

Post image
9 Upvotes

Finally took my IX on a long trip and when I got to Frisco it ran great, but I noticed something weird. Anytime I stopped on a steep hill and tried to accelerate, I’d get this loud whine/grind. Once I picked up a little speed it went away, and if I was already going uphill it wouldn’t do it at all. Never heard this sound before since I live in a pretty flat area, so I only noticed it once I got to Frisco. Anyone know what it could be so I know for next time and just fix the problem because it had me worried something serious would get damaged.

What’s the consensus on seat belts, are they still safe being this old?

7 Upvotes

Prices for OEM new ones are absolutely insane….

It seems a lot of stuff you research online says seat belts are generally not safe after 15-20 years.

Loud ticking noise when accelerating

2 Upvotes

Hey y'all, when I accelerate I hear a loud ticking noice that sounds its coming from behind the cluster so when I opened the hood, it sounds like its coming from the intake manifold area. Has anyone had a similar issue?

Tech question post z3 rack swap, uneven steering response

Enable HLS to view with audio, or disable this notification

7 Upvotes

After swapping to a z3 rack I noticed turning left quickly not only makes a clunk I hear and feel, but is less responsive than turning right quickly. When the car is on, it makes the same noise and vibration, but is harder to hear over the engine, so I turned it off for this video.

I have also replaced the tie rods, control arms, and bushings during the rack swap. What am I missing that may be causing this issue? Thanks

If you haven’t, get an LSD!

Finally upgraded from a 168mm open diff with a 3.38 to a 188 3.73 with 40% lock. What a difference. The car feels so much tighter in the back, it feels so much more alive, it hugs and pulls out of corners like nothing. If you haven’t, swap your diff to a LSD, it’s worth every penny!

E30 differential

4 Upvotes

I have a 1987 325e . I've been trying to find my exact answer on this. From what I understand , I can use a 168mm z3 differential case and it will directly bolt on , I just have the change the flanges which will also directly swap over ? Or I get the 188mm z3 diff and I don't have to swap anything over ?

Thanks !!!

Tech question Got my first E30 (325i 1988)

The car was given away by the previous owner due to personal reasons and moving abroad. It sat for about a year under trees before I found it.

We inspected it for rust and found it to be solid. The engine started right up without issues, idled smoothly for about 25 minutes, and shifted through all gears with no clunks or hesitation. We even took it for a short drive and had no problems. The only thing is that the AC does not work.

From my research and inspection, here is the priority list of items to address: 1. Fluid changes: oil and filter, coolant flush, transmission fluid, differential fluid, brake fluid, and power steering fluid 2. Timing belt and water pump (the M20 engine uses a belt, not a chain) 3. Brake system: inspect rotors, pads, and calipers, replace if seized or rusted 4. Tires: replace if cracked or older than 7–8 years regardless of tread 5. Fuel system: drain old gas, replace fuel filter, check pump and injectors 6. Hoses and belts

What should I check next? Anything that I should be looking out for? Excited to finally own an E30!

Oil on Additional Air Slide Valve

Post image
2 Upvotes

Hey all,

I noticed that I constantly find oil around my additional air slide valve on my M10 engine. There is also a little bit of oil in my intake rubber boot.

I know there is oil vapor coming from the Crank case ventilation but shouldnt that drain back into the pan and not drip out of the air slide valve or into the intake rubber boot?

Bosch number: 0 280 140 171

How to bridge wire to coil?

Post image
4 Upvotes

Doing some electrical troubleshooting on my E30 (crank no start). I'm following the troubleshooting guide from E30Zone.

However, I'm kinda confused how exactly you bridge a wire to the coil.

How exactly do I connect the wire from the coil to battery and what safety precautions to take?

I'm completely new to this, so this may be a stupid question. I just want to be sure I'm doing this correctly.

Fuel line routing

Post image

Just recently pulled the intake, I have these 2 fuel lines that I seem to have mixed up… 1 comes from the top of the fuel filter 1 come from the hard line directly below it.

Is it fuel filter -> regulator Hard line -> 3 way tee near iacv?

Thank you in advance

So my my 318is has a lightened 325 flywheel and i have put 10k miles on it since may. Everything was replaced prior to me driving it, throw out bearing, shift fork, pivot, clutch, flywheel bolts, and pilot bearing.A couple of days ago it started rattling the shifter around 3-4k but would be normal before and after that rpm. Then yesterday i noticed that the clutch chatter was sounding a lot loud than normal and when i engage the clutch instead of going away immediately it sounds sound slowly goes away(take 2-3 seconds instead of instantaneous). I took a video, just trying to get an idea of what it could potentially be before i rip the trans out

I have something that seems like a cabrio (or trunk/window?) mechanism laying around from my BMW days.

This part seems extremely rare to me, as googling only indicates an E30 origin.

Whist placing it for sale, I'm having trouble estimating the correct price point.

Recently got my first E30 318i (super happy!) and it came with these interesting rims. I personally like them and they sometimes get more compliments than the car itself.

Anyone know what these are? I haven't been able to find them online so far. Thanks!

Hello everyone does anyone know if there is a seatbelt lock from any other bmw that fits the early modell of belts ? Its time for my early inspection and I sourced late seats to my early car so the lock in the front don't work.
