Thanks it's not that I am not grateful for the advice just guess when you get contradicting information it takes my confidence away regards the car, that I will ever resolve the issues lol.
just another note it's never failed when driving but has since yesterday played up staring when warm which till today has not been an issue.
Does anyone recommend a place to by these valves from.

You can get the rail valve on ebay mopar no 5093924AB.
