Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards

If you are using that much oil you either have a BIG leak or your BURNING oil through bad rings
