Hey guys and gals.....We did it!!!!!
 

I'm happy to say the job of installing the convertible motor relief valve has been sucessfully completed. :icon_hyper: This forum provided the know-how and the encouragement for the completion. It was a real team efford! With this team behind me I might even try some other stuff ? Later this week my 1999 xk8 goes in for secondary tensioners, water pump and thermostat. The car has 17,000 miles on it , so it's all for prevention. I got a price of 1,100 to do it from an jaguar experienced repair shop. I had gotten quotes that were about 200 dollars cheaper but I don't think they were all that familiar with the tensioner work involved. Your thoughts would be appreciated. THANKS AGAIN FOR YOUR HELP ! mick99
