I personally don't think its the bores mate, obviously the garage have inspected it but its usually fixed with replacing the stuck lifters. Never heard of it being piston slap in any b204/5 engine though your confussing this with the engine out of the 9000. they had good engines in them.not the later 9.3/9.5 motors that are made of chocolate.as i said ive scraped two the last was a 2001 aero estate that was piston slap it was bog standard and had done 90k ,it was a minter but not worth doing.they just don't make them like they used to |

Tbf the b204 that are in the early 9-3s are bullet proof, good for over 500bhp on stock internals and are exactly the same as in the 900 and 9000s except obviously on some 9000's you get the 2.3 version.
The b205 is a revised version of the engine and your right the internals are curse word and they have problem with sludge because of the pcv system and oil pickup.
I'll be using a b204 bottom end on my b205

either way, the car is now screwed  picked up from the garage earlier this eve, got two minutes down the road when 'KLUNK' something let go in a big way. engine cut out and I had to wrestle the car off the road safely. car is now parked up at side of road ready to be picked up by the garages recovery later on. to me it seems they left something loose with the way it suddenly let go, left the cam loose maybe?, a lifter shouldn't cause a complete engine lockup like that! dunno where I stand now, I presented a working but loud car to the garage, and now have a probably scrap locked up engine. I don't really know what a reasonable course of action should be. |

Could be your DI cassette mate, they can let go out of nowhere. My other 9-3 was running perfect and just cut out on me one day, ballache but an easy fix.
Does it turn over?

no, it doesn't turn over it cuts all the lights and does nothing. something clattered internally just before it went.

If something definitely clattered its got to be something what they've done mate, without doubt.

I've changed lifters before then 5 mins later the head fell off a valve, nothing to do with the work i did but did the owner beleive me? did they fook we need more info before slating a garage. Even then long distance diagnosis is difficult at best impossable at worst, not all mechanics are monkeys but then even the nest make mistakes  |

Well I'm not planning to blame them for it, it could have been a genuine mechanical failure. but if the fault does turn out to be theirs upon inspection i'd hope they'll admit to it. maybe a joint cost resolution or something. time will tell.

At the end of the day his motor was working before he took it in, I know curse word happens but the diagnosis was already made, so if they had fixed the problem that he had paid them for, he'd be driving it home not hearing an internal noise before it packed in on his way home. |

if you did a post mortem then you will most likely find the cam bearing caps on no4 trashed followed by the key way on one of the cams sheared . if they have had the cams out check that they have put the bolts in the caps the right way round as one has a slot to feed oil from the lifter to the cam ,if they get muddled up then the cam gets no oil . the slotted bolts go on the outside of the cams

cheers all, only time will tell now. The garage should have recovered the car last night and are hopefully stripping it down to see what happened. I cant afford a huge repair so If it's a major fault (I suspect it is) then I'll have to scrap the car. Hopefuly I can come to a fair deal of some sort with the garage in question.

Its spun a shell by the seems of things and locked itself up solid. Garage transported the car back to my house foc. ah well, Now breaking a saab 9-5 , currently trawling ebay to see what bits are worth. seems I might be able to make a fair bit back on it if I'm lucky. wish me luck folks.
In other news I'm now looking for a car/van big enough to fit a 6ft doublebass laying in the back

So nothing to do with the work the garage did ? Are you sure it was a top end rattle and not a small end? the constant hammering of a small end will wear the BE shells and make them thin enough to spin, not had that happen for a good few years but back in the day i had that exact same thing happen to a pinto in a cortina, it has started to rattle earlyer in the day and the AA man and me said to the owner it was the cam (which is the usuall pinto rattle to be fair) it later seized solid but when i striped it the cam was perfect, the small end on the rod that spun it's BE bearing was worn, also had it on a Mk1 1900 Cavalier and an E30 BMW, last 2 times a "mechanic mate" had told the owners it was the cam, in the case of the BM a specialist garage had diagnosed it as cam and changed the head (even though i told him it was the small end) but his mate was a BM specialist and knew BMs i was a ford man so he chose to beleive him, needless to say i got the bottom end change job  Small ends sound VERY like a cam rattle and TBH first time i was fooled you have to hear it to tell it's that close to calling it a cam rattle very VERY close sounding, a stethoscope would have pinpointed the sound but on a modern engine with all that clutter in the way it's dam hard to tell. |

I guess if there's any doubt then on a modern engine a scope on the nearest knock sensor (or even a cheap microphone) might let you know the frequency of the noise, allowing you to narrow it down to being from the cam assembly or not. (Just an educated guess though, I've never tried it!)

Small ends sound VERY like a cam rattle and TBH first time I was fooled you have to hear it to tell it's that close to calling it a cam rattle very VERY close sounding, a stethoscope would have pinpointed the sound but on a modern engine with all that clutter in the way it's dam hard to tell. I'll second that. Had a crx with a small end gone and i lost count of the amount of times i set the tappets on it to no avail. I was also about to chip in earlier and say i've never heard of lifter bores wearing in a modern engine and if you've got any kind of rattle on one of these saab engines its going to be from the bottom end. |

Which could meen a mis diagnosis by the garage if it wasn't a tappet bore wear issue?, i know a lot of mechanics who have missed it, it's one of those "once missed forever rememberd" noises that prick the conscience when you next hear it. Mechanical diagnosis can be a very tactile job at times |

well the car is now scrap I would think , The car is only worth £1000 ish and a new engine was quoted at £1695 fitted and warrantied for 50k miles or 5 years . A bottom end job is not something i'd like to tackle on my drive. shame as the car was mint elsewhere.

I put a S/H engine in one of these last year for a customer. The whole job came to about seven hundred notes including parts and i even mot'd it for him.
You should be able to get a decent engine for around four hundred notes i would have thought.
