Run round to Mercury yesterday but have a drip drip from somewhere on the l/h side of the engine as you view it from the front. It's coming from somewhere above,in and behind the oil filter. I have very little manoeuvre room and have no removable panel to view this side of the engine. I could not see any leak from either the pipes to the injectors etc I'm inclined to think it might be a split diesel return hose which disappears up there somewhere but will find out more tomorrow.
 
If it'll help I have a manual for the 4JH-TE that I downloaded from a website a few years ago.
 
Just to update. I found the rear injector was blowing - all my fault as I'd had them out for servicing. I believe the small seating washing near the nozzle was not seating correctly. I took it out, cleaned it and re-installed it. All now ok. Will PM lpdsn thanks.
