Well, I posted a message a while back concerning oil not getting to my overhead cam, and I'm still having troubles. I have a B21F engine by the way... a couple of weeks ago I was hearing a ticking coming from the engine block and I discovered that no oil was coming through the cam journals when I took the top valve cover off. It was suggested that I remove the second head bolt and clean out the hole with a drill bit. I did this and great progress was made. Oil was coming up through it seemed all of the cam journals but the one closest to the front of the car. Interestingly, the oil has been coming out of the journal closest to the back of the car very rapidly, and each successive journal towards the front seems to allow less and less oil to the cam. I guess my question is how does this system work so I can understand how this is possible, and also how I can get oil to that front journal. I received a suggestion to remove the front and rear galley plugs and clean them out, but I'm not sure exactly where they are. Thank you for your time in looking at this, its a long one, but I wanted to be specific. Hope your Volvo's are running good!
