ive hot an annoying , leak from the passengers side (UK) your drivers side of the engine , its not a massive one get no drips on the floor , at first I thought it was a split in the steering boot , as there is oil on the boot , but after cleaning and eventual removal ( steering part replacement , its not coming from inside the boot , its dripping onto it , ive taken some pics to see what you lot think
it seems to be dribbling down the metal bendy ribbed pipe more than anything else, what is that connected to?
Cheeers

Steve
oh engine is a 02 . 4.4

rocker gaskets were changed 6 months ago , covers removed, no oil on spark plugs so inner gaskets are ok
is the corrugated pipe the shielding for the power cable?

As everything is coated with oil the best bet will be to remove the aluminum plate from the bottom, give it a good bath and the leak should present itself.

The prime suspect of such a scene is the valve cover or the chain tensioner.

This is an aggressive leak from chain tensioner. First pic shows a drop coming off and the second shows a stream coming down whatever the part is directly below.

A tiny leak would likely just get blown back from the fan and splattered everywhere collecting on whatever has the most surface area and dripping down.

Clean it all off. Maybe wrap some paper around the tubes and tape it on well and drive a bit. You can investigate a spray pattern to determine a source. (don't worry paper and oil have nearly the same flash point. If paper would catch on fire the coating of oil should already have done so.) Make absolutely sure the paper doesn't touch the exhaust that does get hotter than flash point for both.

Report your findings. I'm sure a majority will have the same type of leak eventually..

help me find my oil leak 😊
 
The left side is the left side. When looking toward the back YOUR right side is still the CAR'S LEFT SIDE.

So you are saying the leak is on the LEFT side of the engine? (Or to use the nautical term PORT side)

Do you know it's engine oil? The power steering is notorious for slow leaking on the LEFT side of the motor. Either way same method to find the leak. Clean well, cover with something clean and find the spray pattern.

M62 on the sedans has a remote oil filter in the front left corner of the engine bay plenty of good spots to develop a leak. Does the e53 also have this arrangement? I know some 8 cylinder have the filter on the bottom. I did a little work on E53 with N62 but don't recall where the filter was

E53, N62 engine, oil filter is on the bottom of the engine. Actually an easier oil change than my Buick and I'm not one to say much is easy on an E53.. I've had my oring leak here before and it doesn't present anything on the front of the engine but the belly pan will sure tell the tale as will the bottom of the engine itself.
