Help! Burning real gas. And blowing Smoke.

[DrGarv.]

As i said in the subject line, My car burning real gas and blowing white smoke , real ragged vibration and very little power. When I checked under the car I realise that some gas actually leaking from the exhaust.

So i'm thinking that it may be a bad coil pack or spark plug. Any ideas, advice? My engine is a 1.5 Zl-de

Maybe it's a blown head gasket. Did you check the coolant bottle to see if there's oil in it?

[DrGarv.]

No oil in the coolant bottle...
How much to replace the gasket if that's the problem.

Bluish = Oil
Blackish = Gas
White = Transmission fluid???

Just came from the mechanic, he said one of the injectors is just dumping gas into the cylinder and it seems to be a problem eminating from the brain box...

Checked the coil pack they are good...
Checked the injectors they seem to be good...
Cylinder head, questionable, but appears good...


So I need a brain Box for a ZL engine...

The white smoke was gas evaporating with the heat through the exhaust. One of the injectors was dumping fuel into the cylinder constantly, and not in pulses as it should be.
As such the problem was not the following:

Head gasket,
injector,
Cam or Crank Sensor,
brain box,
throttle position sensor,
Coil pack or
bad spark plug.

The problem was caused by a short in the harness. It was positioned badly between the intake manifold and the firewall so rubbing and heat in the back the caused some exposed wiring and eventually the short. Harness is now raised and well shielded.

So i'm ready for the next mazda lime, now it's to just fix the aircon, and the speedo and the hold button, get wider tires, some good rims, cradle arm bushings balance and align...

I got my shots for the Mazda Malaria... hopefully this is it for the while, but I have to find some where to do some hi speed stability testing

glad it all sorted out
