hehe thanks!
Now off we go to solve the next 2 issues:
1) to check on the diff noise and final decision of diff ratio -Guess will give a try to a rack and pinion from 3.45 to see 2 things: a) if noise stops and b) if I like it a bit longer
And also to 2) solve the oil fumes issue - fumes way less now, but still there and smelly, and I guess I am going to air filter box way in order to turn them in?? if this might give us the solution

11.09.2017 - Now I saw I should be writing Crown not Rack :-)

Oh, and also a 3rd one: the weird issue of water temp rising up whenever I drive uphill

(Yes I know all the above are off topic, but they're still the remaining issues to find solutions after my clutch slipping issue which seems now to be resolved)

Whats the weight of your current fly wheel .. i think 323i is 6.4kg


A question here: What are the pros and the cons of a lighter or a heavier flywheel?
I mean, the mechanic fitted one from 323i but lightened. However, it is heavier than the other one I had (and -I think- I can feel my acceleration affected abit-or this might be just my idea?)

these guys here give a bit more heavy figures for 2002 flywheels- I guess they are the same for M10s?

Anyone any opinion on heavier/lighter flywheels-and if lightened, how much?

Lightened flywheels do give you better acceleration but once at speed the engine has to work harder to keep that same speed because of the lower inertia the flywheel provides.

If your engine has not alot of hp and your flywheel is to light your uphill speed will be affected .. the engine will have problem to keep its revs up when going uphill.

With the former flywheel I did not have issues on uphill chases :-D
In general you are for or against a bit lightened flywheel and how much?

Oh maybe the answer I am looking for is here: After replacing for a different flywheel, should, in general, webers be again set up??
