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.
I'm in the market for my first E-30 and I had a question about the timing belt on a 1991 318i. I was looking at one and the owner mentioned that the timing belt never had to be replaced. Is this true or is he full of it. I thought he was full of it but I'm the one new to the bimmers.

if you take the timing chain cover off and there is a lot of play on the chain when you push on it then it needs to be chained otherwise no. i have the same car lots of fun enjoy!
Also, think about updating the chain tensioner to a newer M44 piston.
Not all E30 318I are chain driven engines the M10 is but The M40 is a belt driven assembly with a timing belt change interval Approx 24000 miles or four years and at 1991 it must be an M40. And they do damage valves when they snap.

also in 91 it was an m42 and yes they will mash itself apart if it snapps because the valves will stay where they were when it snapped and the pistons will keep moving nad then one valve will be down the piston will hit it either bending the valve or braking your cam hopfully its the first one...
