    Zero HG issues and the engine on the whole is in great shape. Apparently very low idle vacuum - 11 instead of a healthy 15ish. Doing the valves on Monday and will report back. Any ideas on the causes of low idle pressure. Blockage? I'm deeply suspicious of this shitty Oz exhaust system - we have a mental emissions system from the exhaust manifold into two air pulse valves and this combined with the middle box could be the cause of all. Trying to source a standard M30 exhaust manifold and rip this rubbish out.

    Hi Jam, Thanks very much for the response!! It disappears after 10 mins idling and drives perfectly after that. If I start & drive the car immediately it lacks power for about 20-30 secs and then the engine response returns to normal. So (based on my rather rudimentary knowledge) I suspect its either an issue with the HG, head or best case scenario its a crazily excessive buildup of condensation in the aftermarket exhaust centre box - I'm a pessimist when it comes to old cars and I expect it will be a small crack in the head that is very slowly dripping coolant into the cylinder (prob No 2 with the lowest comp of 165-170) overnight and then clears out each morning.......I'm guessing this is the most obvious cause of the vapour/loss of power, but very confused as to why i'm not losing any coolant (hence my desperate hope that its just the exhaust?!?!) . I also wonder if this then rights itself as the head heats up and expands and explains why it doesn't continue for the rest of the day? However, not being a mechanic, I'm not even sure if this is possible?!? I guess by posting up the vid I was hoping that someone would either say definitively, yep that output of smoke is definitely coolant burning off OR No, that vapour doesn't look like enough or have the characteristics of burning coolant (not thick enough, different colour etc) I'm also confused as to why the spark plugs didn't show any signs of coolant fouling?!? The vapour does have an odour, but to my untrained nose it just smells like its running slightly rich. Coolant burning has been described as "a sweet smell" but it really doesn't smell that sweet to me, and I'm not sure I even know what a sweet smell is. Anyhoo, its booked in next Tuesday to get fully checked and I've ordered the centre exhaust section from BMW ($497 delivered from Germany and it takes 2-3 MONTHS!). I've tried to locate a tester solution/paper to test for coolant in the collected vapour from the exhaust but google has failed me (or more realistically, I've failed Google). RE valves - I wouldn't have a clue on how to check the valve clearances, so I'll ask the guys to do this on Tuesday and report back here on findings. Thanks again for your response/thoughts! KR Al

    This is an engine with a full SH and approx 85k genuine miles on the clock - Its a really good condition low mileage car that has had approx. GBP9k spent on it since purchase in Dec 2018. Doing my effing head in and any help, thoughts gratefully received!

    Hi guys, it would be very much appreciated if you could view the attached vid and let me know your thoughts, bearing in mind the following: 12 months ago I had the head gasket and valve stem oil seals done - the head was tested and skimmed and new gaskets fitted all round. $3000/GBP1750 worth of work The compression test done by me last week was 180, 167, 185, 175, 180, 180 (as I was worried that my rings had gone). I don't lose coolant and the car has never overheated. The car has new everything - sensors, AFM, TPS, ECU, FPR, Both fuel pumps all are Bosch or genuine BMW (no cheap parts fitted). Brand new injectors that have been tested. New Spark plugs fitted by me and examining the old ones none seemed to be washed clean by coolant (one was a bit oily). This video is a cold start one this morning and if I start the car and drive it immediately, I have a real lack of power for the first 30 secs. Since the HG work, the smoking has gotten slightly worse. The only thing that is not genuine is the centre exhaust box and I had put the smoke upon start up down to condensation build up in this crap part. Once the car is up to temp it runs beautifully....very smooth and all the power I expect from the M30b28. As you'll see from the vid, the smoke starts after approx 1 min, and continues for 9-10 mins. HG gone again? Cracked head? Anything else?? The fact that I don't lose coolant, the comp test is acceptable, and the plugs are not washed clean says to me that its not, but how do you explain the white smoke and lack of initial power?????? I'm stumped! BMW E28.mov

    528i Distributor advance/retard vacuum lines?

    Thanks Tims! I've contacted him and will revert back to advise if he solves the problem! There seems to be a real knowledge-gap over here when it comes to these cars - they are either useless or mad/arrogant and think its still the 80's/90's when only the rich bought BMW's (and they could charge what they liked).

    528i Distributor advance/retard vacuum lines?

    Thanks Tims - Yes, Mark had been recommended to me and I'll give him a call. I could only find 1 review (google) did you find others?

    528i Distributor advance/retard vacuum lines?

    Forget that - I've sucked on both pipes and worked out that the retard is working. Sorry.

    528i Distributor advance/retard vacuum lines?

    Thanks again for all the replies guys! Just wondering if the central column inside the distributor (the part the rotor arm fits onto) should move slightly in both directions for advance & retard functions? Mine only moves clockwise a couple of degrees and then springs back, which I know is right for advance function. My idle is high (around 1200-1300rpm) and I'm wondering if the idle timing retard function isn't working (either the column is seized or the vacuum diaphram thingy is banjaxxed). Any help would be greatly appreciated.

    528i Distributor advance/retard vacuum lines?

    Cheers Andy. I’ve got those weird electrics unfortunately. Do you reckon it would be ok to bypass these completely? It’s EGR gubbins for Australian emissions as you probably know.
  11. Hi All, Just wondering if someone out there knows the correct way to fit these rubber vac lines - I have one coming from the underside of the TB and one coming from the top - I also have two nipples on the distributor one topside and one underside - Could someone please advise on the correct way these fit? Any help much appreciated!

    Becker Grand Prix Stereo - Removal??

    Good shout - I'll try that now! Thanks for the reply!
  13. Hi All, hope that you are all holding up well in these screwed-up times.........Horrible watching the UK going the same way as Spain/Italy. I'm pretty angry (I'm British, my wife is a British GP and we have over 20 friends that are GP's, Senior Consultants in the NHS throughout the UK) that this useless government could see what was happening on the European mainland and still didn't act decisively enough or provide the advice/PPE required. 1000 dead a day in Spain/Italy was a humanitarian catastrophe but now that we are there in the UK, the media are more interested in whether BJ is safe, walking and doing sudokus....... Anyway, I hope that you are all safe and doing the right things to remain so! Does anyone have a Becker in their E28 - I have removed my fair share of retro radios in the past, but cannot work this one out at all - there is no obvious way/no security tab holes and its in there as snug as a bug in a rug. I've searched online and cannot find anything and wondered if there was anyone on here who had first-hand experience of taking one out without damaging the console/unit?

    Hazards work. Will check fuses in the morning. Can I bypass the relays?
  15. As above! All packed in today. No dash lights ner nothin’. Anyone have everything pack in at once? I’ll check the fuses but wonder if this clearly points to one culprit?? Any help very much appreciated!!
