Talking of Variators, I've asked this before, but does the 8 valve have "variable valve timing" ???
I was told it does and where to find the variator, but then I couldn't find it 'cos I don't think it's there
If my car does have a variator of some description, maybe it's duff as my car is crap below 4500rpm.
Yep, 8V's definately have a variator. I don't think it's in the same place as on the 16V's though.
If you look between the breather hose and No.1 injector, on the left-hand side of the engine, you'll see a rubber 'cap' that fits over the variator, with two wires going into it.
Have a look, it's there somewhere!
It's farily easy to test it.
Get yourself a 12V test lamp (or a multi-meter) and connect it to the wires that would normally go to the variator (careful not to let the bare wire touch anything metal!!). Start the engine, and increase revs. When the light comes on (or the meter reads 12V), that is the point where the varitor should activate. This should happen at about 3000rpm I seem to remember (but I could be wrong). If this test is sucessful, you know that there are no problems with the wiring, and that the ECU is sending the correct signal.
Now, connect two wires to the variator itself. Connect the negative side to the negative terminal of the battery. Start the engine and let it idle. Now, touch the positive wire to the positive terminal of the battery. The variator should kick in, and the engine will get extremely rough or more likely just stall. Again, be very careful not to touch any metalwork with either of the bare wires. If this works, then you've no problems with your variator!
