1 - If you use the vx220 dipstick tube the oil level should be kept between minimum and half full on the dipstick.

 

2 - If you use the later Saab dipstick tube keep the oil level at half full.

 

If you do a 'z22se' and fill it to max then it will probably burn oil

 

 

And a Z22se with a Saab sump? �

I think you have a vx220 dipstick tube, so basically just keep it in the middle

When you go smaller pulley you will need a smaller belt So get one small enough to have the tensioner higher up

Hoping that;) Small pulley is the solution for any problems 😉

[Exmantaa]

Pulley turns in the right direction and with the same speed as the belt, so it should not do much harm.

But if you're concerned, you could move the Alternator a bit out with some washers. Not too much, as you will loose a bit of belt angle on the SC pulley.

That was the first i checked when i recognized it.

It also calms me down that i found no sings of rubber on the pulley.

With regard to the 'breathing' characteristics of these engines, I followed Kieran, Martin and Chill at the national (all with B207's right?) and Chill's was much cleaner than the other two.

 

Are there any other key differences apart from the breather setup that Chill has that might make a difference?

Chill has forged 2.2

[CHILL Gone DUTCH]

All this is IMO There is a little bit more to it than just the 2.2 forged Kieran's runs on CS map so would imagine his pcv system is fully closed Martin is not sure if his orifice in the inlet manifold is open But I've told him to check and replace it with a new Saab one ( like me ) The thing I found with th pcv systems is controlling the amount of suction coming from the cam cover If you have to much suction you pull oil straight into the inlet which also creates the black puffs On full throttle If you haven't got enough suction you also get black puffs because the engine is blowing large amounts of oil in to the inlet On gear change this is when the air changes direction for engine to breath in and the orifice in the inlet manifold allows pressure out as the cam cover breaths in If this system is working correctly you hardly get any black puffs as there is no time for the crank pressure to build in the first place Catch tanks and extra separators etc is only masking the crank pressure which is building up How ever if you want to try and achieve clean laminovas and sc etc they do help I also found that the suction is different dependant on which air filter you have and how much boost you are running I'm probably running less boost than anyone else on a Harrop and probably similar boost to the small pulleyed M62 When I say boost I mean boost pressure in the inlet manifold

[CHILL Gone DUTCH]

Is it a possibility the Saab 2.0 have boost pushing past the rings ? Also as discussed before oil can expand by 10% in a engine Which creates less room in the dump area creating more pressure So should we look at which dipsticks we are using and reducing the amount of oil we are putting in to the 2.0 How much oil do they need ???

[MartinS]

Mine is a total pile of *%&&, and averaging a litre of oil 'not petrol', every 70 miles. With regards its breathing (more like throwing its guts up) I had the breather pipe fed into the induction and thought the SC must be sucking oil out of the car, so pulled it out and fed it into a water bottle (this caught about a tenth of a litre) so its blowing out of the engine. The engine was carefully run in.

Its slower than the old engine even though it has stage 2 cams, a smaller pulley, bigger better exhaust, better air filter and everything else you can throw at it, and when it got hot, it got even slower. I was hitting about 120 down the straight (125-130 last year on ecotec) but when hot 110 and simply will not go over 7000 revs even though the limiters at 7500.

Then the new pipework of the saab set up that feeds coolant to the header tank broke in half.

Its a marvellous thing the Saab engine conversion.

Just to clarify, all saab engine owners check the alloy pipe that feed coolant into your header tank. It is bolted to the top of the engine then is held up by a bracket then the rubber hose goes into the header tank. Vibration I think caused the weld at that support bracket to break the pipe. I had been losing coolant gradually for a week or two and couldn't find the problem as it was a hairline split that probably opened when hitting a bump etc and only when I lost nearly the whole tank on track was it obvious where it was coming from as it was an almost 80% split around the pipe.

Luckily I found a guy near the track on Saturday who braised it up.

This must be a weak point so keep an eye on it.

Thanks Martin. I will have an look. That doesn't sound like a happy end story regarding your saab engine.

[The Batman]

I have a few spare if you want one I reckon need to compare dipstick (oooerrr) length as I think you might be using the wrong one causing to over fill every time and then the engine works harder and burns it off

[smiley]

I am using the Z22SE dipstick on my oem B207.

I was specificly told by my engineer to only fill up to the first knotch.

 

Most of my consumed oil end up in my catch tank. (other end of catch tank goes back into inlet)

No reported black pufs. (so far)

I have been going to the halfway on te stick when topping up and went through 5 litres driving to Snetterton and back with  a load of sessions in between. As you can imagine, I was topping up after every session and every garage stop, and would be very, very nervous running it one of from the bottom of the stick.

 

Thanks Joe but I wouldn't want an original pipe as mine broke after just 2500 miles. The repair done though not pretty, has really beefed up that mounting point so I'll keep that one.

Who's idea was it to put a Saab engine in a VX? 😓 😆 I'm only loosing oil when it's fired out the dip stick lol. Dropped the oil and put half a letre less back in and kind of solved it so more might need to come out the sump. My temps seem spot on but it does loose power after several laps and doesn't have any real top end. Same kind of symptoms as you Martin in regards to feeling slower than a stage 2. We've capped my revs to 6500rpm and added some ignition to hopefully combat the heat issue and pressure build up. Bedford will be the deciding factor for my build, whether I need to have a re think on everything or if it can all just be mapped and tuned out.

When she's running right it pulls like a train and the power delivery is mental top end past 5,500rpm. Left a stage 4 turbo even when they were on boost before me.

Hitec Germany.

I thought Hitec made training shoes. That may explain the problem!
