Astra G 1.7 DTI: timing valve leakage (Y33) 096360-0760

Common issue for Astra G 1.7 DTI with Isuzu engine.

[@user-rf1ef8jc5k]

I have same problem and i want to know if you loose power and have an obd erro p0335 does it refer to this solenoid valve assy ?!

[@geoelectronica]

The engine didn't have power loss. In my case the issue was only fuel leakage and no error.

[@sergiofernandez6096]

I have a Meriva with a Y17DT engine, it loses power between 1500 and 2000 rpm, during this problem it releases white smoke, above those revs it works correctly. Could it be that solenoid?

[@geoelectronica]

Hello, If you have a dense white smoke, then it seems that is a serious condition. It might be 2 situation: 1. Problem related cooling system like: cylinder head gasket, engine block cracked... 2. Fuel system: issues with injectors, high pressure pump... Regarding Y33, this is a pressure regulator, normally this one doesn't lead to white smoke behavior.

[@sergiofernandez6096]

@@geoelectronica Intake, Turbo, EGR, CAT, Pistons and Engine in general are fine. White smoke appears only during failure, then not. It is as if it went off point and was left behind. That's why it's a pity that it could be that sensor The EDU module could be?

[@geoelectronica]

@@sergiofernandez6096 Is hard to say, a diagnosis is necessary. You can do swap test if you have a valve/ EDU from another car.

@@geoelectronica OK, thanks for answering

Hi just been told my fuel pump is leaking is this the main cause as I'm hoping to follow your video and replace myself let me.know your thoughts kind regards

[@geoelectronica]

Hello, If your pump is the same as mine, most probably the leakage comes from the Y33 valve. But you have to check first if indeed the fuel comes from that valve. Is not so easy to replace it, but if you have the right tools and time you will succeed.

@@geoelectronica thank u very much for the video , such wondring what should i do to test the y33 valve

[@geoelectronica]

@@alibenfarhat1302 I don't know exactly how it's works, in my case the fuel leaking was the problem.

[@doomdylan]

I replaced it, now the car doesn't start anymore. Do I need to bleed the circuit? How?

[@geoelectronica]

Hi Luca. Isn't needed to do any bleeding. The engine should start easy. Maybe there is another issue or you forget to connect something back.

[@doomdylan]

@@geoelectronica Thanks for your answer. I managed to start the engine by spraying in the intake, with injector pipes unscrewed. I left the car with no valve for days waiting for the new one, perhaps it got so much air inside the circuit that it couldn't bleed by itself.

[@geoelectronica]

@@doomdylan I'm glad that you started engine. Cheers

Hey, maybe You know what are the dimensions of the O-rings?

[@geoelectronica]

Hi, Unfortunately I don't have a valve available to measure, but I found in my notes the exterior diameters of the O-rings: - The big one ~ 20mm - The small one ~ 10mm

[@Rogaldinho10]

thanks! @@geoelectronica

My 1.7 dti astra g car jerks at near 1.700 rpm in second while going 30km/h. It does the same effect at 1.100 rpm. Could this valve be at fault? At other rpms it goes fine. Thanks.

[@geoelectronica]

Is it hard to say, the better way is to put a tester on the car. (diagnose)

[@Adrian-re9fh]

@@geoelectronica I did the maintenance of the car and when I looked over the car I saw the the cable that connects to that timing solenoid is leaking diesel. I will try to make the same process as you did to repair it and try to see what happens, thank you anyways.

[@geoelectronica]

@@Adrian-re9fh All the best & good luck!

[@Adrian-re9fh]

​@@geoelectronicaI finally replaced today that timing solenoid, and wow the car is running really well right now. Anyways I recommend people who have this problem to clean all those cable sensors with alcohol isopropyl and then dry with some compressed air. My car is running now perfectly without jerking or something like that, thanks for that video by the way. Cheers.

[@geoelectronica]

@@Adrian-re9fh Hi Adrian, I'm glad that you succeed to fix your car. Thank you for sharing here your experience. All the best!

My opel corsa c 1.7 dti isn’t starting on its own any more i have to push starting it once it start is ok any idea new coil and glow plugs have electricity on them cranks no start some times it starts straight way

[@geoelectronica]

Hello, You may check if there is no leakage into the fuel system and I'm not speaking about visible leakage is more about depressurize the fuel ramp.

[@hitmen2025]

@@geoelectronica taked the valve out cleaned now the car won’t start at all theres no diesel coming to the engine any idea why need help asap cheers

[@geoelectronica]

​@@hitmen2025 If you only cleaned out the valve, then could be an issue regarding sealing, so please check if the o-rings integrity is ok and also if the screws are well tighten. Another cause could be the electrical connection, please check the connector, no diesel contamination is allowed also the wires integrity is very important, I mean the insulation.

[@hitmen2025]

@@geoelectronica only one is tighten the other on managed to taked out like 2h then couldn’t put it back on so i pit only one started ok next day dead no fuel to the injections
