Tubes are an easy fix but the cam covers are expensive to have them resealed by a mechanic and a major DIY project.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a very small leak on the left side of the motor, there is a bit of grim and light oil mist so cant quite pin point it yet, but just curious to know of there is something that more regularly leaks oil on the left side? I leave about a 10c piece every could of weeks. Obviously ill get it checked out, just wanting some heads up
What did you use before for oil?
When you say left I assume you mean drivers side?
Cam solenoid seal is the best I can guess without seeing a pic.
I just replaced both this winter. Very easy job.
Not sure what was in it before, whatever the car yard had in it.
I mean passenger side (on a RHD car)
So the left side.
I was thinking AOS possibly as well, bellows?
Thought the AOS is on the water resevoir side in the front of the engine.
There's always a valve cover leak. Got any pictures? Valve covers don't use gaslets, just sealant.
It's not the oil, the M1 5W-50 has a higher viscosity index than most oils on the market at all temps. I had a small leak from the same area and it was a bad clamp on the AOS bellows.
The connection for the breather hose from the AOS that is located at the upper rear ob the 4-6 head/cam cover is a common source for a leak on that side.
Thanks for the input guys, doesnt seem like its a major either way... is there an updated AOS design? I wont need the motor sport version since its a DD.
Typical leaks are the cam covers and the spark plug tubes. Tubes are an easy fix but the cam covers are expensive to have them resealed by a mechanic and a major DIY project. But if it is the cam covers, try taking out the lower cover bolts, clean them meticulously and goober lots of permatex red from the middle of the bolt to the bolt head and reinstall. Don't overtorque the bolts. I had 3 or 4 that were leaking and was able to get all the leaks fixed except for one bolt on each side. I can see a small leak but it doesn't drip on the floor.
What he is saying is that inside the head where the spark plugs are housed there are plastic tubes with an o ring at each end of the tube and if these o rings go bad then the oil will get past that seal enter the hole where the spark plug is housed and possibly could fill up with oil and leak out externally.
Here is a pic of the tube. When you pull the coil out of the hole you will see where the tube is.
