Hi Oilman, I use repsol elite competition 5w-40 synthetic in my M40 and on colder morning start ups I would hear about 2-4 taps comming from the engine. Other than that all was fine. I have now change to the Repsol elite multivalvalus 10W-40 semi synthetic and have not heared the tapping sound since...

Cheers Dannyboy, will have a look at the AFM an see if its floppy.

Hi, On hots days while driving with the a/c on, after have been driving for a while, the idle seems to drop about 200rpm and just before comming to a stop and I push the clutch in to put car into neutral, when the rpm drops to idle the car drop below idle to about 500rpm and seems like it is going t...

My 318i sit at a 1/4. When stuck in traffic and will creep up to half then back down again. On hot days with the a/c on will be at 1/2 way.

I've got a dec '89 318i and I need a new rack cause of too much play, so will any standard e36 rack firt the E30?

Is there a procedure for replaceing the oil spray bar? I imagine it to be straight forward.

heh eh ehe yeah I know that nulon stuff is for worn engines but that's the only the thing that would stop the continual loud tapping before I got the head rebuit. But I suppose it was better the timming belt snapped cause then I head re-done as well cause I still would of had that loud tapping, wher...

Are all the Motul sythetic group V eg. 8100 or is it just the 300V range?

My M40 seems to tap all the time, when cold and when warmed up, its driving me mad! That's what mine used to do. I tried this nulon product which stopped it http://www.nulon.com.au/products.php?productId=e10 then my timming belt broke an got the whole head re-done. The timming belt was over due to ...

Not unusual foe the M40 to tap a little when cold, and personally I wouldn't worry about it. A change of oil grade may be worth trying - may make it better or worse, but in any case, the knocking is harmless. Oil spray bar in the head can become partly blocked, is almost impossible to clean, but is...

Hi, Am after some sudgestion. I've recently had the head done on my car (@160,000km), new valves, sleeves, springs, etc. The cam wasn't replaced as was still in good condition and was re ground. I'm running a 5W-40 synthetic oil and wonder if a little tapping noise when starting up when cold is norm...

Cheers, will do

Hi, I've got a dec 1989 built 318i 4dr sedan with M40 engine. I've been told to use castrol magnatec 10W-40 (semi-synthetic). I also have on hand some Repsol elite competition 5W-40 full synthetic at home. Which one should I use? Personally I think I should go for the Repsol but am interested to see...

Hi, I'm new here, live in Australia and have a 1990 e30 318i which I bought 2nd hand. Has about 164,000kms on the clock and recently have had the head/valves done (due to a snapped timing belt). Have been told to use catrol magnatec semi-synthetic 10W-40, which I already have bought and will do and ...
