  1. Originally it probably used SAE 30wt. My 1929 tends to like 40wt.( oil pressure wise anyways). I currently use modern 15W-40 diesel engine oil. Since my 1929 has roller cam followers , I am not concerned with adding zinc. Im pretty sure the diesel 15w-40 oils have high zinc already.

  2. I have encountered improper valve adjustment that kills power and causes difficult starting, while hot, two different times over the years. In both cases hot valve lash was too tight. When the engine heated up, the valves were slightly open . Opened the lash up and a perfect running engine came back. I think it was due to valve and seat wear that causes the valve lash to go away. One was on a fairly fresh rebuild the other was a very high hour industrial engine. Each engine started and ran normal when cold. After sustained load, power went down , the engines chocked down and died easily. Wouldn't start when hot. Let them cool 30-60 minutes and engines cames right back to life. At first I suspected old ignition components.

  3. Hello. Shown is the link that may list the parts that you need. However I am not suggesting that you purchase these parts as much as I am suggesting that you use the application list to source parts from a later and much easier to find wheel cylinder. Many new replacement wheel cylinders are under $10. In that case, if the new wheel cylinder contained the correct pistons, you could throw the cylinder housing away and have the new parts that you need.Just a thought. Good luck.

  4. Hello. I am about to replace my door glasses. I have looked at the Steele companies offerings related to the door glass. Have any of you replaced your door glasses? If so which of the channels and other parts were required to do so? Were there any tricks required? I am hoping for a straight forward and easy job.

  5. I think that your 1928 would have great similarities as my 1929 Buick.

    On mine the escutcheon turns separately from the crank/knob. The escutcheon should have male threads that will thread into the mechanism housing. The reason that the escutcheon wont turn separately from the handle is due to the pot metal that was used then. Parts produced in that era are subject to high failure rate. The parts tend to grow and almost seize to each other. I have had issues with them on my 29. Sometimes they can be freed up and sometimes they cant. I used to use PB Blaster in the process.

     

  6. Engine noises can be tricky to pin point, even with experienced ears. Valve train tends to be more common than other sources. Accessories including fuel pump can be a cause. Excessive play in components operated by the camshaft can affect camshaft life. The constant hammering can eventually take its toll.

    Piston slap / wrist pin noise. Sounds produced by this is not good but the engine can probably be babied and used with caution for a fairly long period of time.

    Main bearings can be noisy at times but these old engines can limp by for a long time as long as oil pressure remains strong.

    Rod bearings may fail quickly and put a connecting rod through the block.  Use caution here. If concerned drop the oil pan. Inspect and measure the connecting rod journals and check bearing surfaces as well as check clearances.

    You may purchase an older Chilton or other manual which may aid in diagnosing various engine noises.

  7. Mr Engle is correct. My 1929 has freeze plugs behind the lifter covers. They are prone to rust through which yields coolant in crankcase oil.

    I might have removed all spark plugs and left oil drain plug out while pressurizing the cooling system to determine the source of the leak.

  8. I do not recommend attempting to rebuild your own fuel pump.The first reason is the scarcity of the pump and parts. There is a fair amount of expertise in rebuilding these correctly without causing damage. Most of the larger rebuilders have some spare parts that may work to replace your broken or worn parts. Pushrod length is critical to the life of your fuel pump. Excessive slack can produce a hammer effect which can damage the fuel pump parts and the engines camshaft. Surely someone reading has a engine with the correct pushrod length that could be measured.

  9. All this coolant knowledge makes my head hurt. On my 1929 Buick I cleaned the system as best as I could. After this my coolant circulated so fast that it foamed out of the radiator. I put an inline thermostat in the system, it completely cured the foaming over.

    For coolant I use 2 gallons of full strength Peak or Prestone anti freeze. I also use a coolant conditioner that is used in almost all commercial diesel engine cooling systems. I use the Fleetguard branded product. I think it is all produced by Nalco , regardless of the packaged brand.I have seen inside diesel engines 15-20 years old that used this product from day 1 . There is no corrosion of any sort when properly used. Not even any browning of ferrous metals. I drain and flush every 3-4 years and refill. Its not expensive or exotic. The coolant conditioner really helps. Careful it can be overdosed. Ebay item number is 143765646265. It is available at almost any heavy truck parts counter and NAPA.

  10. To prevent a cracked exhaust manifold be sure to use the correct type beveled flat washers under the manifold nuts. I even lightly grease both sides of my manifold gaskets. Watch the fastener torque as well. The hardware must allow some thermal expansion during use.

  11. More than likely the slack that you are experiencing is play in the advance mechanism. This is totally normal. You can check your timing with a timing light. If the mark stays fairly steady throughout various engine speeds you are ok. If the mark is all over the place then you could have wear in the drive gears, breaker plate, points or the advance mechanism.

  12. Many Buick cars had really good owners in terms of good maintenance and little abuse. There are 80 year old cars with engines that have not been rebuilt that still perform well. They tend to leak a little but perform well. In many ways I would prefer an unmolested engine to one that has been rebuilt by someone with no expertise in that series engine. Chances are if your car has good hot oil pressure that your oil clearances are acceptable. It would not hurt to inspect all the bearings but small imperfections don't mean an overhaul. Rings would certainly help. A cylinder head rebuild could possibly yield better performance.

  13. Start by inspecting your camshaft lobes closely. Engine use with bent pushrods can damage the hardface on the camshaft. Piston pin wear and piston slap can all cause noises. These noises can change with a change in engine temperature. How good was your oil pressure ? Now would be a good time to service you oil pump. If pressure had been low before , you may consider raising the oil pressure with a shim in the relief valve spring area. As long as rod and main clearances are not extreme you can use your car for many miles with it making a little noise. You can easily spend thousands on a correct engine rebuild. Many just run a heavier oil and drive.

  14. Bill that is great news. I will admit that I never had to tickle the clutch disc in my clutch but it seems like they may be slightly accessible via the small holes in the flywheel. After posting last time, I remembered a second time my clutch stuck. It came free after maybe 50 yards too. I don't view it as a big deal , but it can definitely be a surprise.

  15. Bill your car is punishing you for ignoring her for such a long time. My car had a stuck clutch after being dormant for about ten years. I got it warmed up on jack stands . I got it out into the open by towing . I started it in first gear and proceeded to drive it with the clutch pedal on the floor. I took about five minutes of throttling up and down and actually popping the throttle several time. I knew not to be too aggressive. It suddenly came loose and has worked well since. If this doesn't work you may have to hold the clutch pedal down with a stick and gently pry the friction plates apart from the steel plates in the clutch assembly. Good luck.
