Can someone tell me what I should be looking out for when applying 12v dirrectly to my VTC selenoids please?

I am trying to determine if they are actually working or not.

I imagined that I would hear a positive click each time I connected/disconnected the live, would this be correct?

well, i know that when my VTC solenoid connecter cooked on the turbo when it found its way down there, my engine ran like crap.

Just back form a 20 mile blast up the M69 and she ran great. guess I can rule out any problem there then.

A bit of an update.

I connected Data Scan up again tonight and used the active test function for the VTC test.

It forces the valve timing control solenoids to function when at idle. I did them both connected and then one at a time so as to test them individually.

The manual dictates that during the test, the engine will stall if both solenoids operate correctly. This exactly what happened, even when I disconnected say the left one to test the right, and vise versa, she still tried to stall.

Only thing that I am not sure of is, the noise it made during the test.

I know that the solenoid valves are operating at the wrong time during the test but they were quite rattly.

Would this be to be expected? or is it a bad sign?

To be expected really, pretty common, it's the VTC springs inside the 2 sprockets, they weaken over time and create that rattle. New ones are pretty cheap, and a pretty easy job to change.

Cheers Tudor,

That sounds very promising. I have started to worry about it being something more serious, but your diagnosis sounds very likely.

Not too sure when I might be able to tackle the problem, but am I at risk of doing damage as things stand at the moment?

 

Also, I can replicate the noise every time I put her in the garage. I have a slight incline leading to a small step at the opening of the garage, and when I slip the clutch and add throttle the noise occurs when under load. Does this tie in with the VTC springs do you think?

Dose it sound like this

Hi Markderby,

That sounds very much like my issue, I will try the same test tomorrow with regards to disconnecting the VTC during revving the engine. If that is indeed the problem, what would be involved in the remedy?

Thanks guys, I feel a bit more relaxed about solving the problem.

It will be vtc as it'll be activated by the load

 

The noise is nothing to worry about, just annoying
