daverclasper Posted September 20, 2021 Report Share Posted September 20, 2021 (edited) Has always done since I had the car (about 20,000 miles ago). Uses about a litre per 1,000 miles I reckon, not ragging it at all. Plugs are not fouled (a bit of oil around the bottom of threads on some, though on different plugs at different inspections). Had even compression when I tested it a while back, and no different figures with oil in the plug holes. Usually (but not always, I think after a run it doesn't, rather than slow traffic driving, it does) smoke when idling. No smoke on start up. No noticeable smoke when driving (though hard to see). Any ideas please. Can live with it, though interested what may be causing it?, or any simple ideas to cure?, eg Italian Tune up, to de glaze bores, or is maybe running down the head, via the valve stems?

Pete Lewis Posted September 20, 2021 Report Share Posted September 20, 2021 the official triumph consumption was not far off what you are getting ,having said that most get far better have you recalibrated the dip stick next oil change add the specified amount less 1 litre mark the dip stick as low add the last litre and mark as high does this come close to the dip stick marking had the wrong dipstick in the 1600 and that would indicate over fill by over a litre ie the sump may just be too full a simple and cheap check on next oil change Pete Link to comment Share on other sites More sharing options...
GFL Posted September 21, 2021 Report Share Posted September 21, 2021 Doesn't sound too excessive to me, my fully rebuilt Vitesse engine needed half a litre every 1000 miles or so. Maybe a clean and check of the Pipes to and from the Smiths emission valve and also check the rubber diaphragm in the valve is in good order with regards to the smoking when idling If the car is performing well with good oil pressure I wouldn't be too concerned.

Pete Lewis Posted September 21, 2021 Report Share Posted September 21, 2021 Dave from other comments you have made i still have the thoughts you are running a bit rich and bore wash will smoke at idle as would unburnt fuel, wont help your oil usage but would reduce any smoke at a hot slow ide Pete Link to comment Share on other sites More sharing options...
daverclasper Posted September 22, 2021 Author Report Share Posted September 22, 2021 Thanks folks. Will check the oil volume, against the dip stick next oil change. Also lean off the fuel a bit more. Link to comment Share on other sites More sharing options...
JohnD Posted September 22, 2021 Report Share Posted September 22, 2021 Daver, You're not factoring in Triumph's Patent Anticorrosion Chassis Oiling System! If you have no actual oil leaks, aren't you worried that it will rust apart? John Link to comment Share on other sites More sharing options...
Chris A Posted September 22, 2021 Report Share Posted September 22, 2021 Also , if there are no oil leaks it means there's no oil in there! 1 Link to comment Share on other sites More sharing options...
