michael.stumpf Posted May 5 Share Posted May 5 Okay, so I took the rocker cover off the engine the other day (after I acquired it because when I topped up the oil it just ran out of the rocker cover seam. When I took the cover off the oil supply to the top of the head looks like it is fed from the front on the right side (as if you were driving the car) and there is a threaded hole approx 3/8" in diameter just inside the cover; seems odd that it is threaded if nothing goes there. My question is should there be some type of oil distribution pipe/line that screws in this hole that feeds oil equally to all of the rockers? Photos would be much appreciated (sorry I didn't take any before I put the cover back on .. didn't think it was odd until later). P.S. also posted question in TeamBuick Thanks very much for taking the time to reply Regards Mick michael.stumpf@bigpond.com Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted May 5 Share Posted May 5 YES. A 1/8th inch pipe from the threaded hole into the top of the first rocker arm stand. Ben 4 Link to comment Share on other sites More sharing options...
EmTee Posted May 5 Share Posted May 5 Here's a picture of the feed to the rocker shaft. This is my '38 as it was when I received it. There is a fitting missing that fits between the block and the line. As a result, mine had a slow leak. I was lucky that Leif (on this forum) had an extra one that he was able to send me. Here's a picture of the fitting and the screen that goes into the hole: The tube screws into the fitting above and provides the mating surface to seal the tapered collar on the supply tube. The fitting also has a smaller orifice than the ID of the supply tube in order to restrict the amount of oil that is supplied to the valve train. Check that this fitting is present on your engine, as unrestricted oil flow will flood the area under the rocker cover could be a reason for oil leaking from the valve cover gasket. Final (correct) configuration below - no leaks: 1 Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted May 5 Share Posted May 5 Good one. If one has a filter this line is the filter return line. Now if someone has a picture of the line/tube/pipe that is under the valve cover. I have not found one in my albums. Ben 1 Link to comment Share on other sites More sharing options...
