320si New cylinder head or could it be new engine needed?

My current stealer has hadmy car for the last 3 weeks now.

Had a 320i SE Auto but had to give it back on Thu.

Latest news is that they do not want to return the car to me as they are not happy it is good - Which I think shows the stealer is being responsible...

The good news was that I got given a brand new E93 325i M Sport with lots of toys. It's graphite with "pimp" red leather. I will post pics up when its a bit brighter. The engine sounds great - Not sure about the paddle shift though prefer manual box anyday.

I've been given it for a week but expect to have it for some time.

When I exchanged cars I asked to see photo's of my cylinder head but was promptly shown my car in the workshop.

The latest is that my engine is now in bits

The cylinder head is off
The piston's are out on the bench
Valves have been examined

They have found cylinder 1 to have some strange markings and have tried a borewash to see if there is a leak where the valves are seated.

They have been asked by BMW UK and AG to measure parts.

It's the first positive action that has taken place but in my mind when the engine is refitted will it ever be the same?

I'm not sure what BMW are going to do - I did ask if BMW UK would fit a new engine in a car of such an age and was told yes they would.

Does anyone have any idea what this would cost BMW?

I don't want the car to be taken back by BMW as it would end my lease contract unless they swapped it for another. As the lease company now charges a lot more for the BMW's so it would be out of my reach.

Mate it will be better, there are rectifying the issue. It was not right to start with.

Some rebuilt engines can be better than original factory ones. Not always though. THIS one WILL need running in, not like a brand new car engine etc which has been bench tested etc.

But they may just source a new lump from the factory which is more likely!

That would prob be the easiest bet for them!

Hope it gets sorted soon bud!

My only fear is when they rebuild the engine they may forget some bit and then bang goes the whole engine or something rears its ugly head 6mths later.

I hope it gets sorted soon too... but not too soon if you know what I mean

Just need to have good long stretch in the E93 in the meantime........

Mate if they made a fundamental error then the engine would not last a week!!

It will be fine and warranty is still in place so you have no worries really, enjoy the 325i.

Is it much quicker than your 320si?

The warranty bit doesn't worry me as lease company either claim warranty or charge my company. Its just the hassle of having to go to the stealers - Trying to arrange cover cars with my diary is really hard. I did just over 2k in the stealers car - so will see how many miles I do in the E93


Strangely enough it feels the same as the si when at "motorway speeds"

The engine just sounds great - but its not loud enough (the si is much louder). With the hood down it's excellent - had some fun posing in it on Fri.

The si has a good engine (when working properly ) and the E93 is heavy.

I am sure you will get it sorted it sounds like they are trying to get it done

Be interesting to see what you think about the E93 handling compared to the si, I guess you have a heavier engine as well in the E93 so not a direct comparison ??

The handling is not bad for a convertible.

My last car was a convertible and it scared the crap out of me on potholes.

It sticks to ground quite well I have "tested" out a few roundabouts and some windy rounds It does loose it at times bit like the normal E90 but its really good for a vert. The road noise with hood up or down is excellent.

I would definately buy one with my own money.

Mixed blessings in a way then. I would have thought that a re-built engine should be perfectly fine, especially if the technicians know what they're doing. Presumably before they consider fitting a whole new engine, BMW will be awaiting specific reports from the dealer regarding the 'condtion' of the engine, specific wear and tolerances etc. The reason I say this is because my father had an E46 323i which had the alleged 'low sulphur content of the petrol' had caused the piston rings, bores and valve seats to wear VERY prematurely. The engine was examined in great detail before BMW said 'fit a new engine'. Next engine was spot on.

Whatever the outcome, I hope you get your car back as it should be. But in the meantime, enjoy the E93.

i heard those homologation special engines are a bit gutless actually. As in you have to work them hard to have them rev into red to keep it going and really for daily driver you are better off with something like 320d or 320i even with new 170hp motor. The Si is just too tricky, albeit it comes with lots of little cool touches, ultimately its a marketing gimmick.

hope they just put in the new motor and it all works ok. I'd be more calm about that then they took it all apart and put it back together. In fact i'd lobby for them to do that rather then fix it all.

I don't think it's a gimmick. I think I would have been bored with a 320i or 320d (I prefer petrol to diesel's).

The 320i Auto I had I thought was nippy but it didn't have that good acceleration like the si above 50mph. The Si is quite close to the 325 when between 50 - 80 mph. The engine noise is something else - It does really sound like a true touring car even though its a 4 cylinder engine.

If I had to choose again I would have gone Si again. You really need to drive one to know.

I actually like have the rev happy engine as I drive with binary levels

I think BMW are going to swap the engine, I just happen to be assisting their R&D dept at the moment. As I also work for a German engineering company I know what they can be like.

I think this is the route they will take. Few dealers have techs capable of building an engine, you can't just follow TIS.

The time element is also chargeable to BMW, so i fancy they'll slot another in, but i wouldn't think there is an oversupply.

Nothing wrong with it -I would have had it in the Si if I had the option (Cheap enough that is!)

I'm just wondering if they have any spares for the engine or any spare engine assemblies. Seeing as it was a short production build. They may have ditched all the machinery tooling. Can't see it being cost effective to have tooling mothballed.

The original engine was 'hand built' at Hams Hall just outside Birmingham. I think there were about 2,500 made in all.

I bet it's a bit of a pain for BMW to make another one given the limited run.

They would normally exceed the production run to include "service mode" for eventualities like this.

Any idea what sort of capacity would they allow for? I'm just interested in how you would calculate such a figure for such a limited production build. I can understand how they calculate for run of the mill engines.

The cylinder block is cast over in Landshut not in the UK. I know the engines are assembled at Hams Hall, I did think about seeing if I could get in to see the plant - as my company tends to deal with the other plants (been to Swindon Pressings). Maybe I could poke the person who built my engine in the eye

Just got word from the stealer this evening.

They have ordered a new cylinder block and pistons.

How are the valves affected if only the cylinder block and pistons are changed?

It really depends on why they are changing the cylinder block and pistons, any idea

Does that mean you are going to have to run it in ?

I'd refuse it back. Cars are never the same after having an engine strip down. Experience has told me this......

The valves wont be affected mate, ideally if there going to the lengths of using a new block aswell they might aswell re-build the head. But they wont because its probably fine and they dont want any more expense!
