I've seen hex head idle adjust screws only as shown below.

You will find more details in th the V12 Bible (page 3-4) Part numbers of retainers, which I bought for my car: - 19B-6336 1939-48 Flathead Ford & Mercury V-8 Lower Rear Main Rope Seal Retainer - 91A-6335 Ford Upper Crankshaft Seal Retainer 1939-1948 Good luck

Ask Pete Phillips from this forum. He has a lot of Buick Series 50 parts. https://forums.aaca.org/profile/77451-pete-phillips/

Here are some pictures showing the position of the diverter plate. I showed the water pump on the driver's side (LH). Regards

Hello, I'm interested. Email sent

During engine overhaul, 1941 and earlier crank shafts nedd to be cleaned internaly from oil sludge. You should remove plug caps, one per crank, to do it. If this is not done, your bearings will fail quickly.

Below is the info from The HV-12 Rebuilding Bible By Jake Fleming Page 10: Most people using a late block with solid lifters install a brass plug in place of the check valve to keep oil from flowing down the lifter supply line. In some cases they stop up the forward end of the lifter line also. Originally the front spring for the 3/8” steel ball was a 1 3/16” long free length. The purpose of the front spring and ball was to pop open at about 20 pounds oil pressure to flow oil to the timing gear. If pressure was low, and many were with some miles on them, the gear might not get much, if any, oil. Several ideas for a better oil supply have been tried, such as a small supply line from the big cap bolt in back run to the front to dribble down on the timing gear. Another idea was to drill straight down from the check ball area and hit the supply line for the front cam bearing. Then plug the front end of the continuous pressure to the timing gear. I did not modify this on my hydraulic model, and if you run good oil pressure like 45 to 50 pounds cold and 15 pounds or so hot idle, the normal oiling method should keep the gear lubricated. Page 15 WHY NOT USE SOLID ADJUSTABLE VALVE LIFTERS? Blasphemy you say! Nonsense, say I. Les Keeton of Anderson, CA uses this setup and his V-12 is the quietest engine in the universe. There are some hitches. The re-builder (you) needs to take care of some important details. 1. The oil feed folds for the hydraulic lifter galleys, both front and rear need to be blocked off (see Fig.1). These oil passages are not needed for the solid lifter. Flat heat Ford V-8 engines do not have these oil passages for the solid lifters, so the V-12 doesn’t need them either. The proper solid adjustable lifters have side grooves which pick up oil from the crankcase via splashing. (See Fig.2). 2. You should (not must) use a 1936-1937, H6251 camshaft or have your 86H or 06H-6251 camshaft ground to 1936-1937 specs. If you use the hydraulic valve lifter camshaft (86H or 06H) as is, be prepared for some clatter as the lobe contours are for hydraulic lifters ONLY. Specs for the 36-37 Camshaft are as follows: Intake Opens Intake Closes (Degrees B.T.C. (Degrees A.B.C. after before top center) bottom center) 19.5 degrees 54.5 degrees Exhaust Opens Exhaust Closes (Degrees B.B.C. (Degrees A.T.C. before bottom center) after top center) 57.5 degrees 16.5 degrees 3. An oil line, made up of 1/8” brake line must be installed between the rear and front 6666 oil relief plugs (See Fig. 3). This way the cam gears can have plenty of lubrication, something they did not get much of with the hydraulic lifter setup. Drill and tap each 6666 oil plug (center top) for a 1/8” pipe size 90 degree inverted male elbow, tube size being also 1/8”. The tube must be custom fitted to each end with an inverted flare and 1/8” male fitting (See Fig. 4). The solid adjustable lifter to get is the SEALED POWER #AT-770 still available at any good auto parts outlet. As stated previously, they have large lubrication slots that pick up oil from the splashing of the crank as it revolves. If the lifter oil passages are not blocked off at the source, most oil pressure is lost at the first two lifters and all pressure by the third and fourth. It is not essential pressure like crank and rod bearings but it is wasted, so block them off and let the cam gears get it. Adjustable lifters should be set .014 cold, between lifter top and valve stem bottom; then re-set again after a run-in, hot. You can use the old ’36-’37 solid lifters (non-adjustable) if you do not have to grind the old ’36-’37 cam, but if you grind the camshaft you must use adjustable lifters. With this setup you gain a lot of oil area so need less oil volume; consequently, the old 86H-6600 or 06H-6600 oil pump. It pumps half again as much oil in volume, but you must use the 56H-6688 oil pan tray to accommodate the pickup. Best yet, use the Melling M-19 oil pump, made to replace the pump in the 1949-1953 Ford engine. It bolts right in except you have to re-direct the oil pickup tube, no big deal, believe me. This M-19 pump uses helical pump gears and is as good as or better than the 56H pump. I have come to believe that the much touted 8El (1949-1951 Lincoln V-8) pump has too much volume, if that is possible; is too expensive and overrated. I had one in my 1947 Continental Cabriolet and had valve float and dramatic loss of power at 55 to 60 MPH when accelerating---who needs that? Oh yes, the Melling pump is also still available at your friendly auto parts outlet for about $25. ADAP also carries them under the SEALED POWER name---ask for the ’49 – ’53 Ford-Lincoln pump.

Hello, You have to remove two long bolts from the back of the starter. Regards

Well, it seems my PM on the hubcap skins was sent 1 hour before Jay. Przemek M.

Thank you for the info. Regards

What is Ford part number of the rear main seal suitable for the Lincoln V12 conversion? I started disassembly of my 46 Lincoln Continental engine and I'm planning to make this recommended modification. Thanks and regards Przemek M.

Please, see below information I found Send me PM with your email. I will send you scan of the manual. Przemek M.

This information comes from Authenticity Manual for 40-48 Lincoln Continental by LC owners club. I have hard copy of this document. I can make scan for you. Przemek M.

Maybe it will help.

Hello Ryan, I live in Poland but I have US shipping address. Let me know what you have from the list I sent you in private message. Thanks and regards Przemek M.
