Guys I truly need your help. I have a problem with the oil pressure in my HP4 2013. The oil pressure is 5.5 Bar at 6.000 RPM and it should be 4.0 bar pursuant to the user manual. This causes that the oil is leaking under the valve cover gasket. The mechanic corrected the gasket 3 times and the oil is still leaking - so it seems not to be an issue of the wrongly placed gasket but rather the oil pressure that seems to be too damn high.
Do you have any suggestions what might be the cause of the issue and have you experienced such problems in the past.
Have you had your valves adjusted recently? There are a bunch of O rings under the cam retainers. Does the bolt in video have a copper/bronze look washer under it's head? Some of the cam retainer bolts have washers some don't.
If the gaskets have been replaced then I think you'll need a new cylinder head or cam cap. I have seen cracks in the cam cap that cause plug holes to fill with oil. Gasket replacements never fix the issue. Some have had new cylinder heads fitted.
