Hi everybody im new to this game so here goes....
I recently bought my first Jaguar, after hankering after one for years. Drove it 300 miles from where I'd bought it to home.
Car has certified LPG system fitted, single point injection type. There are 3 main problems
Low compression on 4 and 5 (prob head gasket gone between cylinders? Is this common? I'm not to botherd about this as I've been working on classic sports cars for years (Lotus' etc)
The second problem is the noise coming from the someware near the back of the car, sounds like a howling gail (swooshy type of noise!) from a distance and is audiuble from very low speeds under all acceleration conditions. I'm know these cars suffer from weak diffs, but is it just the bearings that go? Or does the crownwheel and pinion wear?. She's got 130k on the clock.
The third prob is a vibration that occours when the car reaches
45-50mph and changes into top gear (sports box). Its quite bad, but as speed increases it lessens to nearly bearable at 90mph.I know the box locks up in top gear so that drive is transmitted without slip through the torque converter, could it be somthing to do with this part of the box? I've no experience with this type of box...HELP!!!
