3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
Just bought a 318i today, its a D-reg and i needs a little work doing to it before i can enjoy it fully.
Now she is blowing a little bit of smoke on tick over but it goes away when driving it normaly, there is also a little "ticking" noise coming from the engine, maybe head tapets or leaky exhaust to head gasket, not sure as i've not looked as yet.
Will this just be down to worn piston rings?
Also i would like to service the engine, change the headgasket and cambelt (if its cambelt and not cain driven, really don't know as i've never messed with a Bmw before)
Where is the best place to buy bits from and what oil should i use.
What should i look out for, problems?
The rear seems to move about a bit (tramp) and i would like to replace the bushes.
I hope you guys can help me on some of the above issues as i would be much appreciated.
I agree with witeshark, your valve timing could probably use some attention. And even if that doesn't solve the clicking, you'll get better gas mileage. You have a timing belt, not chain. Most people use 20-50 oil in E30s. I use it in my 325, and I don't think displacement makes a particular difference in what kind of oil you'd want.
