Okay guys have an update .. first things first checking the rocker shafts. Decided to check the uppe first as that is just half an hour ..
couple pics attached for discussion .
.
one of the upper shafts looks like it has moved slightly has it not ? I put it in flush and now it is sticking out
On the other side I have a blowup of rockershaft. The head of the bolt was definitely wet. When I look closer could that be a piece of an RSR seal poking out ? not quite sitting properly ?
the part I don't understand is how it leaks down if I sealed right across the cam housing.
But anyway thoughts are appreciated from the more experienced.
I will check the lowers next but I want to go for a drive first to se if maybe this fixed it. Fingers crossed.
