Any one now of common leaks on these , My under belly pan is covered in derv and obviously leaking from some where , Not a noticeable loss in MPG .

Any ideas as to where its coming from , Had the belly tray off and bottom of sump has diesel on it .SO has most of bottom 1/2 of engine has some (front ) couldnt check the rest .

I dont want to run into garage untill I know / uderstand where leak coming from ,

Is the drain tap on the bottom of the fuel filter housing tight ?

yes no leak from tap , Fuel housing is bone dry on the outside . Few years ago had a injector leak derv, just nipped it up and cured that.

After reading Haynes book of lies Ive got a funning feeling it could be hose to HP pump .. But its beyond me to check .

I will nip up all the high pressure unions once a work what I can see . but I think its from the pump end but I belive the Timing belt needs to come off to check . Problem is I havent lost econemy , well not noticeable
