Oil leak. Please help

[fcfanatic]

Hi guys wonder if someone can give me some advice.

I have a 2005 MX-5(miata) 1.8.

For a while now I have had a small oil leak The problem is nobody cAN NAIL the source. It has been to my local mechanic and a mazda main dealer. Both suspected the rocker cover gasket but 2 new ones and still the problem. The oil is trickling down from the top of the engine at the front and onto the sump then obviously the tray.

I can trace the oil up as far as the main block at the very front of the engine there a black plastic covering that is connected with the rocker cover gasket behind this there is moisture(oil)

What is this black cover hiding and is it oil filled.

I'm subject to driving around in the Mrs honda cars at the moment.

Cheers

Matt

Either the cam seals are leaking or there is a leak in the VVT control solenoid. Both are under the cam cover and the upper black cover on the front of the engine in the vicinity you are talking about.

Thanks for the heads up.

Just one more question. If i was to look up the solenoid what part do I need to search for exactly. I think you may have hit the nail on the head. just need to be armed when I go back to the main dealer with some knowledge ;-)

Apologies, VVT solenoid was the wrong word as I meant VVT actuator (BP6D-12-4X0A is the part number if that helps at all).
