    P.S this is a 07 Rxp

    regards Robert

    First check your compression.

    Take a look in the how-to section,you will find all specs and manuals over there,about pulling the head,and retorque the bolts.

    http://www.greenhulk.net/forums/show...t=pulling+head

    You can pull your head ,and leave your engine in the hull.

    You don't need to suck your oil out,you must however drain your coolant on the rideplate,there is small drainage bolt over there.

    Good luck!

    Have you pulled the head off before? Are the two bolts inside the cylinder head in front of the timing chain installed?

    I'd take the head cover off first and checkthe tension of the head studs and those two little screws down below the cam sproket - maybe the oil is coming from a loose sensor cover or the tops seal?

    i retensioned the head to check and the two bolts inside the timing cover are there and also tight...

    is the riva gasket the way to go, or rotax, or oem gasket??

    FYI, the rotax racing head gasket is just an OEM head gasket with two layers removed

    Just out of curiosity here. But is this Head Gasket thinner, or OEM spec thickness?

    The Rotax Racing head gasket is thinner than OEM specs. It increases compression slightly as a result.
