check your power steering pump as its most likely dripping around or onto your water pump

it could be leaking through the thread on the lower front power steering pump bracket that runs through the timing case into the block. or cam chain tensioner...

i would almost garuntee it is your timing chain tensioner as they have a thing for coming loose over time and the o-rings go hard! i have recently done mine with 190000kms on the clock as it was leaking bit over a litre in 5000km as it has full pressure inside the case and i have also done a mates with the same issue!!

in order to fix it u will either need to obtain the tensioner adjusting tool from ford, get an adjustable grinding disc spanner or do what i did and use a pin punch and hammer and u will also need the 3 o-rings which you will see when u disassemble it.

first you will need to remove your intake, thermo fans, power steering pump (leave hoses connected and just move pump out of the road), power steering bracket and then u will be able to see the tensioner and hopefully the source of the leak! when i noticed the oil leak, oil had travelled around both sides of the engine and right down to the sump (which was a pain in the a*** to clean).

if the tensioner does seem to be the source, to remove it, u first need to crack the plug in the center and remove it, then remove the outer plug with which ever tool you choose (which i explained above) and the romove the tensioner which looks like a twisted bit of spring steel withe a spring in the centre (look up some photos of it if your not sure if you have got the lot out, the last part will have a guide which the chain runs in).

once all the components are out change the orings and then reset the tensioner befor you put it back in, which involves puting the components inside of it the twist it till it compresses right down then slide it back into its hole ensuring the guide goes on the chain properly. now put the outer plug all the way and then using a long 4mm allen key put it up the centre and into the end of the tensioner and adjust it out the first click, it will take care of itself after that and then put the center plug in!!

now all you have to do is put the rest back together! u probably dont need all thius but its here in case u ned it

Agree with Raptor1603!Timing chain tentioner for sure!
Runs down and looks to come from lower (PS pump, Timing cover bolts ect..) and it doesnt help you cant see it untill you take the PS pump off

troymans still onto something with the timing cover bolts. it fixed my leak. and it would be the easiest place to start. then tensioner, then front main seal imo.

I took the waterpump off because i wanted to replace it anyway, looked from underneath and saw it was coming from a bolt , sure enough it was the timing chain tensioner plug but i just tightened it up a bit cos it was fairly loose and problem solved cheers guys.

Hey, i got the exact same oil leak as well.

I was assuming that it was the front main seal.

But after closer inspection it really doesnt look like its coming from the front main seal.

Which bolt(s) did you tighten exactly???

So i tried to fix up the oil leak only things are now WORSE!!! :shock: :shock: :shock:

It is leaking more oil than before :(

I removed the thermo fans & moved the Power steering pump out of the way as well.

Looked around & tightened up all the bolts that i could see around & in front of the timing case.

I must admit most bolts took around 1/2 to 3/4 of a turn more to tighten up including the water pump bolts.

So anyways i thought that the leak should now be all fixed up only i am seeing that more oil is leaking now.

its as if the leak looks like it is coming from under the water pump itself.

But there is nothing there to suggest its coming from else where.

I have tightened up all the front timing cover bolts & also the water pump bolts.

I even tightened up the VCT idler puller bolt just incase.

It is 100% engine oil & not hydraulic oil.

I am now thinking this timing chain tensioner plug or what ever it is.
