Hi guys , my another problem with the car .. oil leak
from crankshaft pulley...
the only thing what do I need to order to have everything ready to replace it ?
I just found one of old post on old website
The oil pump is on the front face of the block on the V6, the crankshaft oil seal presses into it and the lower cambelt idler is bolted to it.
To change the seal you have to remove the cambelt so need a locking & timing kit. You then st the crank at 60 deg. before tdc (to protect the valves) and remove the cambelt crank sprocket by undoing the centre bolt but to do this you must use a long bar bolted to the sprocket to stop the engine turning, do not try any other method or you will shear the keyway inside of the sprocket. You will need a breaker bar plus extension pipe on the bolt plus about a metre bar bolted to the sprocket. You have to be careful to stop the crank turning or you will be replacing bent valves as well.
Once the sprocket is off the seal levers out easily, then pull off the spacer and turn it around so the new seal has fresh metal to run on and press in the new seal. You should use a new sprocket bolt as it is a stretch bolt. Tightening torque is something like 250nm + 60 deg.
Then replace the cambelt etc.
or somebody can recommend any place around norfolk/suffolk where i can do it,
still is the option do it by self.... hmm

I've seen oil pooling there before through something as simple as the washer leaking from the front oil cooler union in the 'v'
Existence of oil on the top of sump area like that is not an instant sign of crank seal
Leaking cam covers could potentially do that too :y
-
Firstly clean the area best you can, usual candidate in that area is oil pressure switch.

They all do that sir. Pretty much.
Any oil leak from the front of the engine can end up there. Cam covers. Cam seals. Top sump seal. Oil pressure switch. Oil level switch. Dip stick tube....and possibly the front crank seal too.
Clean it up keep an eye on it. See where it runs down from. Go from there.
But don't worry too much it's nothing life threatening. :)

Agree totally with Mr. Gixers & Biggriffs replies :y. . . . clean all oil off & have a good look where it is coming from :y
As said most oil leaks on these engines end up pooling there ;) oil pressure switch would be my first port of call ;)

I've just replaced the oil pressure switch on mine, as oil was dripping out the end of it. This is a common fault, and a new one is £5 at your local motor factor as it's used on lots of cars.
I then jetwashed the engine to clean up the mess, but an occasional drip from behind the crank pulley is visible with the engine running.
That is a job to do as part of the cambelt change.
