Alnico Blue:
(2.6) I still have this small oil leak where the oil lays on top of the sump flange below the pulleys . It seems to be coming from below the altenator somewhere.

The leak is not a lot , more annoying than a problem, but would like to stop it.

I thought it was coming from the threads of the sump bolts at the front , but now it seems it is not.

Anyone got a pic of the engine which shows where this sensor & its wiring entry postion are exactly or can anyone rule out this as a possible source of this small leak.

TIA Al  ;)

You and me too Al.

I thoroughly cleaned sump and surrounding area to within an inch of its life .Removed and replaced the oil sensor and all seemed fine for a few 100 miles,then the traces of clean oil started again on top of the sump lip and puddling in the hollow below the alternator.

For the life of me I cant seem to trace it either.I have no evidence of oil leaking from the o/s cam cover especially as it was replaced in the summer with genuine,and when you run your finger around the join of the plastic casing and alloy head no oil is evident.


When Nick replaced cambelt mid summer he was certain leak was not front crank seal as that was also dry and it would be causing more of a spray than just the puddle I ,and you ,both seem to have.Its only ever a small puddle,doesnt drop onto the floor nor does it go beyond just the lip and hollow directly below alternator.


Nothing seems to be bolted to the block above that area which could leak oil so like you Im at a loss as to where it is coming from...more of an annoyance than a detriment though.


 

Doctor Gollum:
Oil pressure switch... Front of block, below alternator... There's an angled cable tray that points to it.

Oil level switch unlikely as that's mounted much further back, beneath starter, and sits in top face of sump in an area with no oil... Business end of sensor actually sits a couple of inches below the sump top and engine running there's very little oil around it.

shyboy:
I also have exactly this problem, and the oil always look fresh and very clean. After cleaning all trace of it from the sump lip and the 'hollows' running down the sides of the sump flange, it re-appears directly below the crank pulley and then slowly progresses outwards.
I have assumed that this is the crank seal leaking only when the engine is running, with pressure in the sump being sufficient to force the oil out. I'm hoping that cleaning the breather system effectively might help to substantiate this, but am preparing myself for accepting that the seal will need replacing anyway once it's been breached.
Any further experiences or discoveries would be very interesting to learn.

Its more annoying than a real issue as never "breaches" front of sump lip so never causes oil traces under car...might also be I,m now paranoid about it and clean it away almost the moment it appears and rarely causes oil level warning between changes.

Maybe constant turning of crank may cause the leak when pressure builds up but would of expected it to be more of a spray pattern than just oil laying on the sump lip and hollow below alternator.
