Thanks for posting your findings.

Hmm, hoping mine is an easier fix. I've printed your post off to give to my inde' in worst case scenario. Let us know how you get on.

replaced the bolts and fitted a new gasket
Did you apply any thread lock on the bolts or is it not required? I have a set ready to fit.

www.bmsport.com and www.c3bmw.co.uk both have some of the originals left I think. I ordered one from Nigel at Bexley earlier this week. Dave.

Just a quick update on my Evo idle problem. The car was rocking at idle, and at under 2k rpm on a trailing throttle.

I left the car sitting for a week before booking it in at the local independant garage. They found 2 problem hoses from the crank breather. The first one, an L shape was severely split at the neck, splits so big you could put your finger in there. The second hose had gone soft and had been pressed flat, so was running at reduced flow.

After fitting new hoses, the car still rocked, and the chap thought that it was running rich, something they cannot sort as requires special tools that seemingly ONLY bmw own.

I paid the bill a bit daunted, and sitting in traffic was rocked side to side as I was before the car visited the garage.

Once the car was hot, I gave it some stick up to around 7500rpm in 3rd and 4th, and let the engine slow on a closed throttle. I probably covered 5 miles of A38 doing this!

On pulling up into the car park at work, the car was much improved, seemingly adjusted to its replaced parts. There is still a slight undulation at tickover, but overall much improved.

What tosh.... any reputable BMW specialist will have the tools and knowledge to sort this.

Maybe I should find a new 'specialist'. They were refering to a tool that adjusts or resets the fueling mixture. It may have been an electrical issue, but either way they didn't have one. Anyway, car better but needs a final fettle.

The car is still rough at idle on start up, but when up to temp it is much better. Is there a mileage, or running time that will allow the ECU to learn these new settings? As you can tell, not that knowledgable on the electrics side.

Progress report on work carried out so far. All results are relative to original factory spec. with 73K mile suspension and 30K mile bushes.
1. Eibach Pro Kit springs. Result ~ Lowered the car further than the expected 25mm front and 15mm rear. Car feels much tighter & less "floaty" even using original old shocks. 7/10

2. Eibach anti roll bars ( front set to hard & rear set to soft ). Result ~ Big big stability improvement particulary with fast direction changes, roundabouts. 8/10

3. OMP front strut brace. Result ~ hard to identify the contribution of strut brace alone because it was fitted at same time as ARBs. Edit ~ Removed and then replaced the brace to to check it's effect. Very little difference and then only noticeable when driving like you stole it. 2/10. Do X-brace first.

4. Braided clutch hose ( from Bexley ). Result ~ Big improvement with much lighter action and higher biting point. 8/10

5. Goodridge braided brake lines, DOT 5.1 fluid & Black Diamond pads. Result Hoses ~ Firmer pedal with improved feel. Pads ~ Quick to warm up, powerful, a bit noisy, low brake dust. Braided lines 6/10 Pads 6/10

6. Simota induction Kit, Supersprint Cat back & Remap at Evolve. Work carried out on 21st April. Result ~ 299BHP pre mods, 307 after induction Kit, 309 after induction and exhaust, 319 after induction, exhaust and map. All positive from a driving point of view:- part throttle response, mid range torque, top end power all much improved. Over 4K revs the car feels very quick, equal to E46 if not quicker. Only downside is slightly increased fuel consumption, maybe 1 mpg but I'm putting that down to me using the extra power every time the engine's up to temp biggrin 9/10

7. Eccentric Front bushes. Better response about the straight ahead and much better turn in 8/10. Rear trailling arm bushes. Back end better over broken surfaces, doesn't "sidestep" as much. 7/10

8. Bilstein B6 dampers. Too soft for track work but I think ideal for driving I do on the shocking roads in and around Huntingdon moan Increased the ride height by 10~15mm relative to original 73K mile shocks. 8/10.

9. Lower X brace. Much sharper turn in ~ steering now feels 15K miles old now not 73K. 7/10

10. Geometry setup. Icing on the cake. 8/10

Still to do........
11. Rogue rear top shock mounts. Brand new standard spec mounts couldn't cope with the extra loads, from the uprated suspension, after only 10 miles of "enthusiastic" driving in the Yorkshire Dales !!!!
12. Check & set up the valve clearances.
13. Steering rack from Z3 or E46 Compact. No hurry now geometry sorted.
14. Front seats that grip better than Vadars and don't weigh 33Kg each !!
15. Lightweight flywheel & clutch.

Maybe........
16. Lightweight 18" alloys. ( vanity really wink )

So whats the pros and cons of the coilovers available and cost of each.... I;ve seem the eibach ones on ebay for under £800 but there are some called D2's that are cheaper but seem to be really good spec?

I'm doing much the same in that I want to refesh my wallowy M3 evo and even though I fitted a 2nd hand set of Konis last Nov I think one of the rears has gone so its a good time to fit coilovers.... just which ones?

Well, I'd go again for the Bilstein Pss9s, or possibly the KW Varient3s if they are easier to adjust than the Pss9s. I think they are detailed above.

Got to the bottom of my car's problems. The BMW dealership says its the exhaust timing that is up the swanny. Their senior techs are on holiday until the 4th June, so I have my Dad's Honda Beat to run around it until then. Much, much different to the M3, but skinny tyres, ragtop and 3cyl 650cc is a load of fun at this time of year.

Who needs a 3200 S6?

Joe, what exactly is wrong with yours?

Mine has started to mis-behave a little when cold. The idle is lumpy and the car generally feels reluctant to do anything. However, when warmed up it's absolutely fine.

When you say the exhaust timing is out, is this cam shim related or VANOS related?

I'm due an Insp. II very soon so perhaps I just need the shims re-adjusting?

Hi Simon,

They say the Vanos is fine. A slight gnarly noise on tickover, but functioning well with no leaks. I spoke to one of the guys on the desk, opposed to the engineer, but may pop in on the 2nd June to see what they are up to. That'll surprise 'em eh!!! A BMW customer that is interested in the oily bits!

You'll see my symtoms above.

I'm considering a swop when I get it back. A hatch and something focussed with 2 seats. We'll see.

Simon, did you get your airbox sorted in the end?

Nope,

It's still sitting in my hallway. It wont go on without a remap and the only places to do the remap are 500 miles away. I'll have it fitted at the end of the year when I can cough up enough to have it remapped with spicy cams and the airbox.

Hopefully, it should then be generating something in the region of 360bhp smile

Just out of interest, would a 319bhp E36 really be as quick or quicker than an 338bhp (do they dyno at 338bhp?)E46?

I know that has probably been done to death but I can't seem to find any good threads on this.

My M3 Evo is Standard except for a Simota and dyno's at 316bhp but I haven't managed to find an E46 M3 to test it against yet.

Shamrock ~ The S54 enigine in the E46 feels to me like it has more low down torque than the S50 in the E36 but the E46 is about 80Kg heavier so power and torque to weights are very very close. E46 gearing helps at start and the E36's small front area helps above 100 so in a drag there is next to nothing in it. Check out these links. Even the guys in the E46 have to admit the E36 is "schneller" laugh
