Guest TwinTurboJoe Posted February 9, 2011 Share Posted February 9, 2011 Hi there anyone who can help. I own a 1994 J-Spec TT Supra and I have taken it off the road for the winter. I have been starting it and running it round the block every three weeks or so to stop everything from seizing up but when I came to it today and started it there was plumes of thick grey smoke coming out the back and the engine was sounding a lot gravellier than usual. This has never happened before so any advice as to what the problem could be would be greatly appreciated. Thanks, Joe. Quote Link to comment Share on other sites More sharing options...
ellis Posted February 9, 2011 Share Posted February 9, 2011 Is it grey or blue? And does it smell oily or of petrol? Condensation will play a huge part this winter particularly if your car has been sat for long periods so it may be neither of the previously mentioned. Did you take it for a longish run to get the engine fully warmed through and up to temperature? Piston No.6 (nearest the bulkhead) tends to be the one that sees the most ingress of water if it is that is the problem just as a general pointer.

Nic Posted February 9, 2011 Share Posted February 9, 2011 (edited) You say the engine sounded different, was it firing on all cylinders? If it was missing on one cylinder the engine would sound lumpy - a bit like an old VW Beetle - wouldn't rev properly and would be smokey.

Guest TwinTurboJoe Posted February 9, 2011 Share Posted February 9, 2011 The smoke is grey but quite thick as well and does smell slightly of fuel. I only ran it for about ten seconds maybe as I wasn't sure as to why it was smoking so much. I last started it about three weeks ago and it was fine then so I'm not entirely sure what could have happened between then and now. Quote Link to comment Share on other sites More sharing options...
Nic Posted February 9, 2011 Share Posted February 9, 2011 If the smoke smells of petrol, as I mentioned above it may not be firing on all cylinders ie. one of the cylinders would just be dumping fuel into the exhaust. This could be caused by something as simple as moisture in coil pack connectors, which would explain why it was running fine before and not now. Try starting again and letting it tickover for a while to get it up to temperature, once warmed up try blipping the throttle and see if the problem has cleared. If not try posting a video so we can hear it and see the exhaust smoke. Quote Link to comment Share on other sites More sharing options...
Guest TwinTurboJoe Posted February 9, 2011 Share Posted February 9, 2011 Thanks a lot, I'll give it a try. Hopefully it will be something that clears once its been run for a while. Quote Link to comment Share on other sites More sharing options...
dude Posted February 9, 2011 Share Posted February 9, 2011 You have prob killed the plugs, put a new set in and give the car a good run. Quote Link to comment Share on other sites More sharing options...
Terminator Posted February 9, 2011 Share Posted February 9, 2011 You will do far more damage to an engine buy running just for a very short time repeatedly over the winter, much better just to leave it and take it for a good long drive when you want to put it back on the road. I have opened engines that have not been used for years and they have been fine. I got an old Merc that had not been driven for two years, outside during all that time. Fresh oil and some work on electrical was all we did to it and it started once the fuel system was primed. Quote Link to comment Share on other sites More sharing options...
