Hello gents, im based in canada, just looking for anyone with extensive knowledge on the 2009 4.2l NA aj34 engine. I've been chasing multiple trim gremlins but I've narrowed it down to a couple thing. Valve cover gaskets, both need replacing and im assuming ever other part that entails will as well, breather tube? Seen this a couple times pop up, not sure what it is, but if its an issuse on this model will replace as well. Fuel pump leaning towards some of my issuses may be with it, I've recently rolled over 200k km not miles. Any one one know of where I can order whats needed would be fantastic. All and any advice is also always welcomed.

 

Maybe a transmission service too? Rear diff fluid? PS fluid change? Coolant is 10 years and your past that.

rear diff was rebuilt last year, coolant was flushed as well with power steering and trans.

 

Mine is the supercharged version of your car, I removed the blower a couple of years ago to replace a coolant hose, did all the hoses whilst I was in there. The job invloved numerous gaskets of course. I sourced most of the parts from SNJ Barrett and Jaguar Classic Parts- the latter has a great website with exploded diagrams and part numbers. There were a few parts that the Jaguar dealer had the best price on. Consider replacing coolant hoses especially if they are originals- this is not a cheap exercise (one of the hose assemblies was around $600, the other very similar assembly was $20! Doesn't have to make sense.).
One thing I did that I very strongly advise AGAINST was to have the injectors ultrasonic-cleaned whilst I had the top of the engine naked. This caused massive problems and cost me a new set of injectors.
