[@CycloneCyd]

Yeah, PCV valves are hugely overlooked on most cars. BIG cause of leaks and burning oil

[@briansidle6965]

absolutely impressive as always! You are my 'go-to' guy for my 9-3 maintenance Cyd, thank you very much for these excellent examples, so well put together and documented.

Removing the PCV valve is " Pain in the Butt " ..... But I enjoy watching your vids ! Some time ago, you promised to make a video how to repair the Lumber Support of the driver's seat and I'm still waiting !

Modern Fords and VWs are much easier to change, but more complex valve systems. Ah, yes. So I did. Well reminded.

i have a problem with my car and if you can help me i would appreciate it.i have the saab 9-3 2008 2.0T aero convertible and i have the maptun stage 2 program.the car starts normally,its idle is perfect and i don’t have any error codes.the only problem is that sometimes the boost isn’t enough.when everything is ok,the turbo meter at full speed goes to the middle of the red lines and the car is very fast.but sometimes car is slow at all rpm phase and at full speed the turbo meter is at the start of the red lines.another thing that i noticed is that i don’t hear the turbines blow off sound anymore.do you have any ideas what the problem is?thanks!

[@garygraham7105]

Very good job.

[@CycloneCyd]

Thank you!

Thank you for your video it was very helpful for me and Barry release to because I don’t have to pay for Programming thank you

[@fat2oy]

Another great video 👍, I'll be tackling this during the week, no issues at moment just a preemptive repair. Also gives me the chance to check how my ecu cooling mod fix has held up. edit now done and the valve was starting to leak a small bit with the test blow and suck.

[@CycloneCyd]

A timely change then, proving my point. Thanks.

[@fat2oy]

Also just done this on my saab aero I've got recently, valve was completely knackered on this one and didn't restrict blowing or sucking. Car ran good before so didn't expect a faulty one as it was just another pre-emptive repair but now idle feels better and more responsive at low revs.

[@troy3456789]

Good to see your work again, Cyd

[@CycloneCyd]

Hey, thanks! the Saab is getting some love this year. I've just got an Ice Blue rear bumper (08 on) from Ron and have the car booked in to a classics restorer to sort the rear arches. It's just had a new clutch at malcolm Miles in Leicester and will be going back there to have the head swapped out (for an Abbott racing head I picked up) later in the summer. These are jobs i either can't do because I smashed a shoulder in a few years back, or I haven't got the equipment. I've still got plenty of videos in the planning, fret not.

[@jutto64]

Engineering some type of oil catch can into this circuit would be great, I wonder if some type of simple filter element placed before the inlet/inlets? under the cam cover would reduce oil working its way into the inlet manifold?

[@caractacusbrittania7442]

Love yor tips cyd, and followed a lot of them, particularly the solid mounts two pack compound. On the pcv issue, it's not good for an engine to burn Oily crankcase gases As it lowers the octane rating of the fuel in the cylinder when burning,, Besides slowly building a residue. I know mfgrs do it to lower emissions as one of the reasons. For two months now on my petrol aero, I have been running the engine With bypassed pcv, and a catch can. The engine runs fine, with no starting issues, idling is probably better, The only noticeable drawback is Occasionally I get a slight whiff of Engine burn in the cabin. Other than that, no problems.

[@CycloneCyd]

Ultimately a catch can is the best solution, provided the residue is properly disposed of (unlikely to happen in most cases). In any case, if the engine is in good condition, you shouldn't be getting much oiliness through the pcv.

[@Top_petrolhead]

i see you do the hot tub video 😊 helped me loads that did

[@CycloneCyd]

Yes, that's me too. Just been in it rthis morning in fact. Glorious sunny day here this morning, but clouding over somewhat now.

[@onehundredpicks5531]

Hey I broke a hose the one on the intake. Do you know the part numbers? It's got check valves

[@MrMelcu79]

Any idea of inlet manifold torque ? WIS is mentioning 10 and 22Nm, yet not clear where you have to use each value - out of 8 points.Cheers

[@paulhopkuns1118]

hello, was wondering if it is possible to test the PCV in the SAAB b207 engine without removing the inlet manifold? if so what is the tool or process. ask as though I don't have the symptoms I had a nes PCV put in abot 45k ago as previous one failed and I had leaks in many places. since the replacement of the PCV I have had to replace the turbo as it was passing oil and there is no evidence of the PCV being replaced when turbo was replaced though oil was evident in the pipes to the inlet manifold

[@sampie2611]

I probably should look into this. Aero is burning oil (about 1ltr/3000km) and seems to be going down on power slowly without misfires and such... Boost leakage through PCV could explain it

[@CycloneCyd]

These engines are prone to leaks too. Again, often caused by boost leaks through the PCV

[@sampie2611]

@@CycloneCyd I have zero leaks. Had a Turbo return pipe leaking, but that's fixed. After that I've noticed the increase in oil consumption..

[@michaelwalton3824]

Whats the torque spec of the manifold

[@45graham45]

Could a faulty PCV valve be the cause of the throttle body getting gummed up? I got a P2135 fault code (& limp mode). Cleaning throttle body cured it for a while but as it kept returning I eventually replaced the throttle body. This cured it for about 9k miles but the code's returned.

[@petrokyrtseba7501]

my greetings to a good mechanic, I want to ask you for advice about my car when the engine is not warmed up, it runs fine, but when it warms up, then it starts to poison, the engine runs slowly, the computer showed two codes 7E8 and 7E9, please tell me what the cause of the malfunction is, sorry for my knowledge of English Thank you very much and I look forward to hearing from you about my problem

[@stevegooding5775]

i wonder is this can cause a po300 code ?

[@jorgedelatorre2240]

I got a Saab 9-3 06 2.0 when I put gas it stalls nd smokes a lot. The smell of gas nd sometimes oil , nd lost of boost. I’ve replace bcv nd fuel injector bc it was leaking now I just smell gas no leak. What could it be. Thanks for the quick response

[@Aero93]

Hi Cyd, on some forums people say that it is safe to block inlet pcv hole( saab, cobalt forums), it stops oil getting in manifold and loosing oil and boost... Adding oil catch can on turbo side baffle helps too. Do you think it is safe to do that?

[@CycloneCyd]

NO, don't do that.

[@caractacusbrittania7442]

@@CycloneCyd hi cyd, can you expand a little on your reply. I understand that pcv systems on cars were designed to reduce emissions and help the environment, But it is surely factual that combustion without octane lowering Oily and carbon heavy crankcase gases, would make a cleaner burning engine. A catch can fitted would safely remove what would have been burnt in the cylinders. Just interested on your take on that.

[@SJSOmar]

Is the rebuild of the injectors going to be a separate videos I need to get mine cleaned because I think they are a little dirty

[@CycloneCyd]

Rebuild: kzbin.info/www/bejne/l2jGno2od8aAg5o this is for Denso injectors on B207 from 07MY. Bosch injectors are basically the same but I don't think they have the plastic rings Simple clean with inexpensive tool and cleaner (tool link in description):kzbin.info/www/bejne/bqOrnoFodqiSo80

Hello from Australia, I just wonder if you could tell me where I would find the blinker relay on a 2008 Saab 93. Looked everywhere can't find the damn thing.ta

[@CycloneCyd]

[@carsandtopgear]

Could a failed PCV cause difficulty starting in warm ambient temperatures? During the summer months, my ‘07 2.0T often has a difficult time starting. It’s fine once it’s running! I’ve replaced vacuum lines, crankshaft position sensor, etc. Starting to think it may be this or perished injector o-rings?

[@CycloneCyd]

If it's struggling to turn over that could be this kzbin.info/www/bejne/i3y3lWeXfphgg9k If it's turning over okay, but struggling to fire, I would also check the fuel pressure at the rail, should be 40-45psi when idling, maybe a little more when cranking Also check this out next time it does it kzbin.info/www/bejne/n32ugKR5iJtqrq8 It's surprising what a difference cleaning and refurbing the injectors makes.

@@CycloneCyd Then I can ask here. There is a P 0300 fault in my vehicle, which I could not find a solution for. For this, I changed the spark plugs, coils, oxygen sensor, air flow meter. PVC valve stuck in my mind. Could it be related to that? Thanks.

[@CycloneCyd]

@@user-jn4ge3pu2j PCV is a possibility. If the car has done much more than 50-60,000 miles you should change the valve as a matter of course. kzbin.info/www/bejne/qKCTdIFsiMl3a9U P0300 though, is more often than not a vacuum leak. Your car must be at least 12 years old and the small hoses will be well past their best. Change them all. kzbin.info/www/bejne/lZS9dpiKf92Xl6c kzbin.info/www/bejne/pHqlnHqEbK2Fl9E Also check the inlet mani screws are tight. I've seen reports of them loosening over time.

I’m trying to bypass the ignition switch on my 06 Saab 9 3 Aero…I’m getting a “steering malfunction” message and I’m not paying out the ass for any new “modules”. I’m going to have to take the ignition switch apart and disable the pin that locks the switch. I’ll still get power when I turn the key to the on position but it won’t start the car. I’m going to install a push button switch with an inline fuse and wire one end to the battery and the other to the starter relay in the fuse box. I hope this works because it is a pain in the ass to take the center console apart…Any knowledgable suggestions would be appreciated! Leave a Reply

[@CycloneCyd]

Clean the ISM and put back together with a smear of silicone lube on moving parts. They get dirty and the moving parts stick.

[@OffensiveL]

Do you think a catch can would be beneficial for these 9-3 ?

[@CycloneCyd]

YES, definately. However, most catch can installs I see (especially on turbo cars) are done wrong, sometimes allowing boost pressure into the crankcase. These are complicated by the valve being in the inlet mani. I'm gonna be having a replacement head fitted later this year, after that I'll do a catch can install with video.

[@adelkaaby1]

Hi is this Pvc in diesel car or just petrol?
