regarding the throttle input issue, have you tried changing the throttle body to a different one?

 

[Crazyfrog (Fab)]

I remember it being posted that  'buy these cheap engines' they just bolt in and are better than the ecotec!    What a totally load of %$%^&*&*?:~#@#!!!!! ollocks

I understand your frustration Martin and as we all know the vx can give you massive headache and not only the engine 😔......... Hope you get it sorted soon and re enjoy the vx Have fitted this b207 in the vx and now fully run ,doesn't use a drop of oil,doesn't smoke and the torque on 4 th and 5 th is pretty insane compare to my old ecotec ..... Another thing I know members on here have always been there to give me good advice and to chin me up Hopefully it will be all sorted soon and chin up as well ,I know it is money and stress but in the end it is a poxy plastic car ......but give us smile 😊 Fab

What was done over the old ecotec Fab?

Martins B207 seems to have been the only engine to have given major problems or am I wrong ?�

I've heard of 2 others.

Do you know what the symptoms/consequences were?

[fezzasus]

Or engine build type, are they all 2.0 L?

OK there wouldn't be a British Leyland scenario when they were going down the pan ie quality control went out of the window??

 

 

Plus its not a new engine design that the manufacturing process is not well refined by now, with respects to tooling, assembly processes etc.

 

Saying that, there's still the possibilty (albeit a small one) of getting a bit of a 'Friday afternoon' engine, despite the process being set-up to remove this.. Not sure how long these engines have been in storage either? I doubt this would be an issue regardless..

[Sutol]

Also going back to the PCV system are there fundamental differences between the N/A and blown versions?

No idea I'm afraid.  They were kept quiet, I've just heard of them.  They were early failures 1000-5000 miles so failed after run in and failed in a similar fashion, not catastrophic just not good.

The PCV setup of any passenger car can be described as inadequate at best. Simply put, the ability of a rocker cover weir system to separate oil from gas is pretty poor regardless of design differences. There may be some differences in the pressure needed to activate the PCV check valve in the manifold, however these are just subtleties.

If those two people do in fact exist, then they're wnakers for keeping quiet and not making other people with these engines aware of potential problems that might be addressed. Not like they're not going to have got anything other than sympathy or help.

Interesting, I would be very curious to know if it's split between 2.2 and 2.0 L versions. Sutol may have a point about the original construction being poor, for example, I have seen sizing issues with pistons used for industry standard testing. Some pistons have been too big to actually fit in the bore from the same supplier as previous batches.

I've just done over 5000 miles with mine and is still going so does this mean mine is a good one ?? As for the Pcv valve mine deffo had different resirances from the new Saab one and the old z22se one So I used the Saab one With no ill effects after connecting it up to intake via a seperator Info on the other failures would be nice

[The Batman]

I think 2.2 saabs are safe as need rebore etc etc I think the problem is 2.0 piston bores and/or rings

[CHILL Gone DUTCH]

There was no rebore with the new 2.2 Saab engines Just 2.2 crank and 86.0 mm piston 86.5 if there was to be rebored or a old engine

[The Batman]

Hmm... I change my opinion to problem with 2.0 piston rings then

[techieboy]

Or there is no inherent problem and it's isolated to Martin's engine in particular.

[CHILL Gone DUTCH]

Do any other failures have similar issues to martins engine That's if martins is damaged its all speculation at the moment

[The Batman]

Or it's all down to mapping/fueling issues when first running the engine in
