TDV8 engine issue possibly

[Nomad9]

Hi There,

Out on a trip in WA, was driving normally then noticed things not quite feeling right. Carried on driving fuel consumption went up marginally and has continued to do so, was around 11.8 now at 12.7 and yes I am towing. Following morning noticed some sooty deposits on the back hatch, more so on the drivers side than the passengers. Checked the pipes the drivers side is definitely more sooty than the other side. I have checked the intercooler pipes to the inlet manifold both are fine not split.
I have now done another 1000 Kim's heading home in Perth. The vehicle seems to be running fine just not as good as usual. No engine lights.

Taking things very easily no heavy foot work things seem to be steady as she goes at the moment.

Any ideas?

Cheers Marty

Have you taken the engine cover off and checked the rubber hoses on the inlet manifold? My Vogue split one of the right angle ones at about 110 000km. If it does have a split turbo pipe don't keep driving. It will kill a turbo and possibly the engine.

While there may be an issue - what is most likely is you are seeing is the effects of towing (though could be an EGR though as this can cause symptoms you have).

Having owned my RRS 2.7 for 7 years now I know it soon lets me know with either a dash light indication, a dash message or an annoying gong if anything is actually wrong - so if you have none of these then most likely all is OK. If you had an EGR issue I would expect an orange Engine Management Light on the dash.

As a precaution I would get the codes read - ignore the crappy little things like communication errors and look for anything major in the engine codes like EGR codes.

Good luck

TDV8s will keep going with a split hose and lots of exhaust smoke. Until the turbo on the side with the split hose overspeeds and fails, sending bits through the engine.

Hi gents, thank you for your responses, I was of the same mind in regard to messages gongs and lights, none of which I have seen or heard yet. I am not seeing excessive smoke either which I see as a good sign. I don't have my code reader with me it was a conscious decision I just wanted to have faith. So far this has not let me down. Your responses align with roughly where I am so I'm not missing anything really obvious. The more I start checking the more concerned my wife becomes so I just check normal things like oil and water and we are all fine. Any more developments I'll seek further advice cheers Marty

I had similar symptoms recently, although in a totally different motor. Turned out to be faulty O2 sensor, causing it to run rich on one side.

[Nomad9]

Oh don,t I wish that is the only problem. I thought faulty O2 sensors showed an orange engine light. I have checked the two large diameter short 90 degree elbows they seem fine. Can you do the EGR's on a TDV8 without lifting the bodywork off? I did one on a TDV6 which was a challenge but possible. Cheers Marty

Did you pop the top cover off the engine and have a look at the other hoses?

My tdv8 seems to be running cleaner after MAPs clean.
So many possibles:
• bottom intercooler hose;
• EGR stuck open or fractured valve;
• stuck turbo actuator;
• cracked intake manifold;
• turbo seal on one side;
• CCV filter not filtering.

There are also short straight hoses at the rear of the intake manifold.

I haven't looked under the bonnet of a Sport with TDV8 any time recently, but after replacing my thermostat a month ago I am confident I could do my EGR valves in about 3.5 hours. Obviously no body off in an L322.
