My car is the shop because of cam timing issue (5.0 NA). This is the 4th time. They replaced the timing chain and all ancillaries, actuators, as well as the sensors. The problem still occurs. They contacted Jaguar technical who asked for hot and cold oil pressures. At speed, the oil pressure is good, but is low at idle. The service manager thinks it is the oil pump, but is waiting to hear from Jag. The car has 96,000 miles and even though I bought it used, it has been maintained by the dealer, (I have changed the oil every 7500 miles).
Has anyone else experienced this?
