Grant. Posted February 14, 2011 Share Posted February 14, 2011 Hi all, A friend of mine has a jan speed range rover classic that he drowned in water the other weekend while off roading. He had all the dizzy apart and cleaned it and it was running fine. It then died again ( 2 hours later) And he managed to just get it home on 3 cylinders Hes got to the point of swapping the dizzy out, its had new cap, leads, arm etc etc, however it just back fires and splutters (he said it fire balled out of the plenum this morning!!) The other odd thing, is that the vacuum pipe for the brake servo was full of petrol... Now, im not a petrolly person, however im 99.9% certain that that petrol shouldnt be there! Anybody able to help me out, as ive got to now go and pick up the pieces Thanks in advance! Grant Quote Link to comment Share on other sites More sharing options...
willfromsussex Posted February 15, 2011 Share Posted February 15, 2011 petrol in the hose may be nothing, I have seen old cars do this, it just accumulates over the years or possibly it flooded once . Did it suck in any water or was it just the elecrics that got drowned? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 15, 2011 Share Posted February 15, 2011 A leaking fuel pressure regulator can fill a plenum with fuel... it enters via the small tube on the back of the plenum. I suspect your mate has knocked the bob weights off in the dizzy, a simple enough fix, just dismantle and remantle, takes around an hour including re-timing the engine up.

Grant. Posted February 15, 2011 Author Share Posted February 15, 2011 the bob weights? Where/what are those? He didnt suck any water in, he says, so its just the electrics, however am going to see the car later, so we will see. A friend of his also told him he could have bore washed it, however, I cant see how he would have done. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 15, 2011 Share Posted February 15, 2011 The bob weights are under the plate in the dizzy, they provide mechanical advance based on engine speed, when removing the rotor arm it is VERY easy and common to knock them off and then you have a dizzy producing all sorts of advance when it shouldn't be.... A fuel pressure regulator doesn't need to have been drowned to start leaking, you gave a symptom, the plenum full of fuel, the most likely cause of this is a leaking FPR. To test, pull the tube off the back of the plenum and turn the ignition on, if it is wet with fuel/pissing out then this is your problem.
