God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Mein Auto: 1989 325i
Pinging at start up

I have an 89 325i. It sounds like it's pinging/knocking on
startup. Than eventually fades away. That doesn't sound normal
but this is my first e30 so? Any help?
Also the gearbox(manual) has a high pitched whistle noise
when I'm going 50 and over, normal?

Pinging at start up

What kind of gas do you use?
I would stay away from 85 octane if you're currently using it.
I use 89 in my '90 325i and it runs fine.

I was running 91 when I first got it but that was
eating my wallet lol I run 89 now. I mean, she runs great.
It's just the knocking sound when it first starts up
worries me.

Valve tap, rod knock or piston slap more likely.
Not pre ignition or detonation.

i would try a thicker oil like 15w40 and see if it gets better. or depending on your last oil change, if it was recent, pull the oil filter off, drain it or replace it and top off the oil with lucas oil treatment

I just changed the oil over the weekend-_- super clean oil though. I'm changing the spark plugs this weekend.
Know any sites to pick up spark plug wires with the loom for a good price?
