A bit more progress today, as I'm stripping stuff off it gets cleaned up and put in the house. All bolts labelled and marked. I think I never got over my 1st mecchano set ;)

At least I can appreciate all the purdy bits in the house now ;) the bed is reserved for the head/crank/pistons. The good stuff :) If we get guests to sleep over they'll have to accept the couch lol. My vrou gaan my hard m@er...



I keep coming back to this post. :roflol:

You are a very brave man. :praise:
 
I just saw those videos Crash posted on page 2. I'll let Peter operate on my wife :praise:

And its a new wife... :cartel:

Now its just to pull it out over the weekend, and off to Peter we go.
 
Motor is with Peter now. We'll see how far we get tomorrow with pulling it apart. Cams look sweet considering the mileage. If there is one bit of good that came out of this is I can't emphasize enough of how vitally important it is to change bearings on these things at +/- 100,000km. Its a ball ache yes. Its a damn sight cheaper than a rebuild. Mine is on 197000km, and those bearings (bar the destroyed one on 3, due to oil starvation) were on their last legs.

I am still a bit a bit amazed that the guys here are asking for 20,000. Rand for labour only to change the bearings...i have collected some quotes:

Germany BMW: 20,000 Rand
Germany not BMW: 10,500 Rand

SA Tunetech: 5,000 Rand
SA Evotech 5,000 Rand

:RedNo:

^^^ have you changed bearings yourself before? Have experience in getting it done and an understanding of the amount of work to be done?

Further to that, are you sure that cheaper quotes will give the required attention to details when installing, bearing in mind that changing out bearings isn't as simple as taking the old ones out and putting new ones in? Do these guys quoting lower prices measure the actual clearances and make sure the replacement bearings will be suitable and not create more damage? Does that price include engineering work that might be needed to compensate for wear?

Not trying to be a dick here, but based on the quotes of R5k for labour I'm pretty sure that your engine will not get worked on by experienced engine builders.

So what is tunetech and Evotech??? Butcher? Baker?

No, I never did it before but I know what needs to be done...and I did it several times in Germany with my M3E30 racecar (every year), twice with my M3E36 and once with my M3E46....all for more or less the same amount like posted (no BMW garage but M specialist) with the slight difference that labour is much much more expensive in Germany...

But leave it...

No dude, you getting me wrong. Not looking for an argument, just trying to understand how - with the amount of work involved - it is possible for such a job to be done for R5k.

That's 10-12hrs bud, I cannot understand how someone can do that much work in so little time while being able to stand behind their work? I mean, you looking at around 3 hours just torq'ing all the rod bolts (it has to be done 3 times using stock BMW rods, less time if you using ARP bolts). Then there's stripping all the bits to actually be able to remove the oil pan. And while you putting it back, you want everything to be cleaned as well while you in there and not leave it in the dirty state you found it in.

Yes, you can do it in 2 days - the dealers rebuild engines in that time - but that is a standard mech simply changing bearings and holding fingers that there's no issues. On a Blueprinted motor there's a lot more to consider as opposed to simply slapping replacement bearings in.

Like I said, not trying to argue but trying to understand what it is you getting for your R5k's worth of labour.

The german prices that I know are calculated on 60.00 Euro per hour, ending up in 900.00 Euro for the work.....as I stated these guys did it several times on my M's and all of them ran perfect afterwards...

Got me?

P.S.: I know exactly that we are talking about S-engines and not M-engines and the huge differences between them....

P.P.S.: Do you know how many M-engines were done by Tunetech? Or does anybody have bad experiences?

if you happy with a 5k job then go with a 5k job personally I would rather pay more and know every bolt and measurement has been agonized over

people often complain about skill level and quality of work in SA but when someone does a job in the best possible way the cost goes up considerably because of the amount of time needed

you cant buy Ferrari attention to detail for Toyota money it just does not work like that it is up to you to decide how much you want to spend and what it is worth to you :)

Savspeed will do the Job including bearings for 9k. 12k on the E92 M3. Can't fault Sav's work either

Quite interesting, thanks! :clapper:

But maybe is Sav also the wrong adress and only used to normal BMW engines and the engine will be destroyed within some months....:withStu:

Yeah I can. He did a valve adjustment job on my M3 and cost me an engine two days later when an exhaust valve in cylinder 6 fell into the piston.

Found out his shim box was not properly organized by size, and the wrong size was used in my engine.

So I would advise against Sav.

Thanks Crash, that's sound like an argument! But this could have happened to all engines...

Found an M specialist telling me that there is no valve adjustment on a M3. If they need to be adjustet than something is wrong and you need new parts...:hammerhead:

Andreas, I think you need to appreciate that the standard of labour amongst even the most reputable mechanics/shops in South Africa is quite low. So while you can have the bearings changed for perceivably reasonable prices, I think many of us feel it is simply not worth the risk on an engine as particular as the S54.

I envy M3 owners in Germany who can spend the equivalent of R10k and get a job well done, but here it is hard to find someone who has (1) the right knowledge, (2) the right level of patience and (3) the resulting attention to detail to do the job properly. To get that, we have to pay accordingly.
