Re: Z3 3.0i Intake Backfire Disaster Help Needed!

I found this link today. http://germanautosolutions.com/bmw_solutions/disa_products/m54_m52tu/m54_disa_repair_kit/product_m54_disa_repair_kit.php This has a good description of the DISA valve issue and seems like a quality kit. Anyone have any experience with this maker? I'm thinking of buying one ...

Thanks, great suggestion. Will do that for sure!

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

I hear ya Zed Free. I have decided to go with the low mileage used engine and keep the other one for a rainy day. When I have the time and money I will rebuild the old one and either keep it for the future or possibly look for another car to restore. I got a good deal on a used engine here. I suspec...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

I'm pleased to see that some, or possibly many of you judging from the views on this post, have taken my advice and switched out or refurbished your DISAs. I'm afraid the engine replacement is happening very slowly so I don't have much of an update. I would like any tips or advice however. As the en...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

It won't give an error code - it's a sudden mechanical failure. But do bear in mind that the reason you haven't heard of this problem is that it is very uncommon, so I wouldn't panic unnecessarily. Indeed, I don't want to add to everyone's level of anxiety about this fault. It is a rare occurrence ...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

I would like rebuild instructions for an M54 engine ;-) Actually I'm seriously thinking about doing just that after I have the old one replaced. I'm still convinced that there can't be a whole lot wrong with my original engine. The big problem with keeping my old engine for a recon project is that I...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

Yeah, you would think so but the luxury car parts market is not very competitive here. Most people don't keep their cars long enough to wear them out. Or they just go to their dealer and pay through the nose for everything. This is not a very car savvy culture surprisingly. I was quoted about 950 po...

Here's a link to one I saw today. I may have found one locally with similar mileage to mine. Have to check it out tomorrow. http://www.ebay.co.uk/itm/BMW-330Ci-3-SERIES-E46-ENGINE-3-0-M54B30-306S3-DOUBLE-VANOSE-PETROL-REMANUFACT-/221049849090?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Car+Make%3A...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

I have been doing a bit of searching for an engine to replace mine. It seems the UK has some of the lowest prices in the world. Just not sure what remanufactured means. Any experience with a remanufactured engine? Even with shipping costs I can't do better here in Japan.

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

Just my opinion but all plastic parts become hard and brittle with age. Anything on the intake side has the potential to fragment and bits can stick a valve open then cause the potentially ruinous backfire.

Engine rebuild or replacement???

The latest on this sad story and a warning to everyone with an ageing DISA. Yes, the disintegrating DISA was the cause. Cylinder 4 has about 50% compression but the inlet valves both look ok. Probably piston and or ring damage from the massive intake explosion. Don't say you haven't been warned! If ...

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

Thanks guys, all good thoughts. I will pass this on to the mechanic as he was just as lost as me. I like the endoscope idea too. Although I'm pretty sure I'm looking at a head rebuild at the least.

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

Having read that link Bladerunner, I can totally see how this could have happened. I still can't see though, why three cylinders would be knackered in the process. Any thoughts?

Re: Z3 3.0i Intake Backfire Disaster Help Needed!

The DISA is trashed too. The central spindle is nowhere to be found. At a guess, that's the cause rather than a symptom - DISA fails, spindle sucked into engine, engine knackered. See this: http://www.bimmerfest.com/forums/showthread.php?t=317362 Yes, I suggested the same thing to the mechanic and ...

Z3 3.0i Intake Backfire Disaster Help Needed!

I'm really hoping someone here can shed some light on this mysterious Z3 disaster. I have already been accused of making this up but trust me, this is absolutely true. First, the car history. I bought it 5 months ago. It had 38000 genuine km on the clock and overall is in very good condition. The pr...
