More use on my problems with my 3.9 that has been stood for 2 years. Was missing a little, and puffing fumes out of the exhause like mad. ECU changed, air byepass valve ,colant and fuel tempm sensors changed. Then n otices that the oil is half way up the dip stick> Well smells more like petrol. There is no froth in collant, no crankcase compressio. So out with the injector, tested none leaking?? Compression test show all cylinders but 1 at around 190 - 200 , 1 at 165. Is that enough to cause a probleM I did put in some expensive fuel additive that I was told would clear thge injectors, I did this nprior to testing them. How long would it continue to smoke if the problem has been cured? Any ideas on what I should do next please ?

Thanks for that

No, not rat or bird, I wish it was. The story so far, changed air flow meter working fine, airbypass valve new, fuel temp senor and coolant sensor , new, plugs,leads,distrib cap,rotar arm. Now discovered that the sump if almost full of petrol and oil! Drained out aload. Worked out by removing the fuel temp senor, there was no pressure, therefore all the fuel is going straight through the injector and past the pistons. Have a full rail and injectors on the way, used. So took off the cover, to prepare to fit replacement injectors, removed ram housing to discover that everthing is covered in oil/petrol except one inlet?? Does imply head gasket ? I wish I had never started .

I wonder if any of you boffins out there could help an amature that has run out of skill, trying to sort 3.9I that is missfiring. Car has been standing for 2 years in a garage. Would not start, when it was put away, already had new HT leads, dist cap, plugs and coil. Thought I was clever when I diagnosed rotar arm shorting to earth and off it started. Smoke and S**T everywhere.Stinks of petrol fumes. Will not tick over, is missing and is obviously over fueling.All the plugs are black and stink of petrol. I have carried out the test on the airflow sensor as per manul and is Ok. ECU was swopped for a known good PRC9611 14CUX,mine is PRC7067 14CUX, I am told this should be compatible, did not cure the problem. I think the air byepass valve is stock due to standing so long, but I am told that will only affect tickover and not higher revs. eplacing this valve soon. Other sympton is strange loud whooing noise coming from the air filter. The noise is still there, if I disconect pipe from airflow metre to plenum chamber .(obviosly engine stops) but in that short period, noise is still there. I have found a guy who rents out diagnostic tool, that plug into the socket next to the ECU. The pins on the diagnostivce tool are round, the only empty socket I can find next to the ECU is black, but has flat pins. There is a white plug and socket, that looks like it is just a link connection. Any help would be very much appreciated.
