I'm not sure about your knowledge on these so I apologise in advance if Im not giving you the credit you deserve.
Going back to my younger days, I thought the same and it was a minute leak from the manifold gasket that sounded like a tap - just a thought mate. Hey guys - did they to the 3.9 in a disco 2???? thought it ended in the 1??
Thanks mate, I wasn't sure. I thought they went to 4.0 after the 1. Interesting to know though - did they do the coil packs instead of the Dizzy..... mmmmm?
It happens when the engine is warm,at low and high revs,all of the service records indicate that it is genuine mileage and there is no l.p.g fitted,any help appreciated guys.
What do ya mean... coil pack but no dizzy?
