Daimler Super V8 Rev Problem
I would really appreciate anyones help with this one.Thank you in advance for any help or advice given.
I am the proud owner of a Daimler Super V8 (1999-V Plate) with a full Jaguar dealer service record and 112,000 miles on the clock.
The car has been off the road for the last month or so for the completion of slight cosmetic repairs and whilst not being driven it is regularly started and the engine run for approx 20-30 mins at a time.
After one of its usual turnovers the accelerator was pressed to increase the revs and at this a good deal of water ejectede from both back boxes of the exhaust .This lasted for about 5 or 6 presses of the accelerator pedal and then the engine would not go over 3000 revs but instead the revs kept peaking and dipping even though the accelerator pedal was kept depressed.I took the car for a drive and it drove well at low revs and was as smooth as it should be.I did not get a chance to test the car over the 3000 rev mark due to road limitations at the time but the car accelerated as it should when the foot was put down so to speak.The engine starts smoothly and sounds as sweet as ever and it runs well at low revs it just will not go over 3000 revs and peaks and dips when this is attempted.
I am worried about the water and the engine problem incase it is something serious.Coulod it be due to lack of use or a simple fix.
Very grateful for anyones help.The car is my pride and joy.
Thanks
Joe

Further to previous thread I should have stated that the water stopped after a short time and the exhausts returned to normal.There is no smoke coming from the car and no loss of power so I doubt it is a head gasket that away but I'm no mechanic or expert so please correct me if I am wrong.Again sincere thanks.

Joe, Let me start by saying I'm not a mechanic and I can't answer your idling query nor do I have any idea on what's going on there, however I believe the water being expelled out of the exhaust is nothing more than condensation (warm exhaust gases passing thru cold metal exhaust tubing). If I understand you correctly, the water stops running from the exhaust pipes after the car warms up. This is normal and happens to me on all my cars on start up on cool mornings. Hope that helps.
