Hi all,
Got a rolling project 1990 Defender 90 with the 19J 2.5TD engine.
She drives nicely, accelerating well (as good as can be expected anyway), but have a couple of things I was hoping to get a steer on...
When going up hills c. 3 to 4% gradient and above, the max speed is 50. I've had an indicated 70 out of her on flat or a slight downward slope. Is this normal?
Secondly, she can be quite smokey. The usual two or three puffs of white smoke on start up. At a constant throttle there is no smoke, but as soon as I do anything other than gentle acceleration I get some smoke, the smoke is progressive.. The more aggressive the throttle press, the more smoke. I would say it is like a grey smoke. Not black but not white. Any ideas what this could be?
Couple of things to note:
1. It's got 113k miles on. Original engine.
2. It isn't consistent. Some journeys it will smoke and then other journeys, when the engine is warm, there is very little.
3. I have carried out a full service oil/fuel/Air filters and fresh oil. This has improved performance but the smoke is the same.
4. I've used a bottle of Wynns advanced diesel treatment. Didn't make much difference, but I only used a single bottle.
Thanks!
