Thanks for the help. When did the press-on gear end? Did it end at the same time as solid tappets? I wonder if the rebuilder had a solid lifter performance cam that he installed and was instructed to restrict the oil. I'm trying to make some sense out of that restriction he told me about. Maybe I should pull the intake and see what is actually there and if I reverse the procedure see what happens when it has oil. I'll check those sources for the valve parts and a metal gear too. Thanks Kenny

Thanks for the info. Do you think there is a good reason to block the oil to the push rods? I always assumed the 39 cam (which takes a press-on gear) was a solid lifter (push rod) type, so since that is not the case maybe he called it a 39 cam since it had the press-on gear, but it was actually an aftermarket solid cam & lifters. Any idea where I could get replacements for those 2 valves or how about a metal cam gear. The only one I have found is fibre. Kenny

41Zperson, I think i cluttered up my original post with too much info. I am not trying to patch up a ragged v12. I did not say it had low oil pressure. I was asking about the low pressure oil system. The cam gear broke and I remember the rebuilder said he installed a 39 cam with solid lifters and had blocked off the oil to the lifters at 2 places. I wonder if blocking off the oil to the lifter bores has a purpose. Since the car has been a trailer queen since the 1960s and I am the first to really drive it I wonder if I am ruining the engine with no oil at the lifter bores or cam gear. So far I have only broken the cam gear. If I manage to get a new cam gear on there what will I break next? I want to keep driving it, I don't expect to rebuild it in my lifetime. It ran great, but prior to my ownership had acquired less than 1K miles in 25 years. Kenny

I'm new here and have had trouble finding my way around, so once I found the post I figured I was going to have a bunch of guys directing me to it, but I am glad to direct you. It is on page 4 and has 4 stars. The subject line is engine & transmission identification or something like that. Kenny

I found George Trickett's explaination of engine dating so all I really need to know is where the low pressure system might have been blocked and who has the parts I need to unblock? Thanks, Kenny

I have a 47 Cont that broke the cam gear a couple years ago. The engine supposedly is a 47, but has a 39 cam w/solid lifters. How do I tell which year the engine is? The engine was rebuilt years ago by someone who allegedly was a v12 expert, but of all the previous owners I am the only one that has put some real miles on the car (about 5K). The rebuilder told me that he blocked off the oil to the hydralic lifters in 2 locations I guess because he was using the solid cam. I am wondering where those 2 locations are. Did the early and late engines use the same low pressure system? Looking at some other posts I see that the cam gear gets the last of the oil. I probably need that. Is there some kind of pressure valve that I am probably missing. Do I get to them by removing the intake? Thanks for the help! Kenny
