rattley hydrolic valves

big surprise on the 52/200 .I thought Id have solid lifters on that car ,with a 288 135 hp /5 main bearings
so I got some gaskets for the valve covers ,saved up, and went to the mechanic for my very first valve adjustment for the car .I had a fair bit of valve clatter the engine sounded like a diesel ,but runs fine and doesnt smoke ,id been using straight 30 wt oil
I called to see how it was comming this pm ,and he said guess what you have hydrolic lifters ,and they arnt adjustable ,so your valve clatter is from something else beside lifters needing adjustment
.hmmm... do the hydrolic lifters get gummed up or the springs get old,making loud valves ?? it turns out the timing was way way advanced ;I cleaned off the bottom crank pully and found a timing mark as directed in the site ;it was at 12 degrees btdc ,the distributer had to come out and go back in to be able to get it so it would adjust back to the 6 dbtdc the service manual required ,maby thatll quiet the valves

any clattering hydrolic valve thoughts??
ill have the engine number checked ,it must be a 327 if it has hydrolic lifters unless there were some 288's built that way
wheres the number near the oil filler hole on the flat flange?
