My Jaguar has a problem with sticking valves. I only drive it from April to October and it is garaged all winter. I have put 6,000 miles on it the last 4 years and I have done 3 valve jobs! Just yesterday I removed the valves and found 3 bent exhaust valves and two bent intakes.The valve stems seemed dry. I use Mobil I 15-50 oil, only use 93 octane fuel. The problem seems to arise when I take the car out of winter storage. Any suggestions on how to prevent this or what is causing it?
