VHPD Excessive pressure in head!


F355GTS

Recommended Posts

A question for all you knowledgable Engine guru's out there

 

My VHPD is clearly not as well as it might be!

 

There is high pressure build up in the Oil circuit ie if you start to remove the Oil filler cap on the cam cover it gets blown off by the pressure, also it looks like the crank seal has failed and filled the bellhousing with oil...lots of it (unless the dry sump tank has split!)

 

Looks like the Engine will be paying a visit ot Roger King but I'm interested to know what might cause the excessive pressure
