  1. Has anyone had to preform a rear main seal replacement on a 1939 Pontiac 6 or 8 cylinder? I was looking at my 36 and it is very dry and not leaking underneath. But I have a friend that is saying his rea main seal is leaking. Thoughts?
  2. I was wondering if anyone has removed the pan from a 1936 Pontiac 8 and replaced bearings? I have a rod knock and need to replace the bearings. If anyone has done this would like to see some pictures and some instructions on what wold be the best way to go about it.
  3. Do you think the starter is staying in gauged?
  4. The 1953 Chevrolet 235 is not full oil pressure it is just like the 216. Same oiling system . Only difference is cubic inch ,side cover is small and the distributor cap is taller.
  5. For inline six motors 235 and 216 the bell housings are same only difference in 1949 Chevrolet moved from foot start to push button on the dash. Depending on what vehicle you are putting it in here are things to keep in mind. Inline six 235 motors all the way up to 54 have the water pump in the same location as a 216. When you go to 55-62 the water pump is lower and can cause over heating and or will not fit in the vehicle unless you run an electric fan. For best fitment 54 235 is the best motor to get and run. Other things to keep in mind gas pedal rod on 235 is in a similar location as the 216 but may require some modification based on application . 1953 235 engines are the last year of the dipper motors. They are not full pressure motors like the 54-62 motors. I have rebuilt 4 1953 235 motors for customers and they are not full oil. 1950-1953 235 motors are the same and they are not full OIL. You flip a early 235 like a 53 and a 216 up side down with the pan off they both look identical with the scoops on the connecting rods. using an early 235 is the same thing as keeping your 216.
  6. Here is a video so everyone can hear the sound. Oil pressure stays at 40 I did and oil change and sound is still there 1936 Pontiac
  7. After reading the shop manual it says intake .009 exhaust .011 while engine is at normal operating tempreature.
  8. Cool thanks for the advice. I am gonna order the gaskets and pull the covers off. I am guessing it is best to remove the access panel on the fender also so it is a little easier to service ?
  9. Is this something that is common when a motor has been sitting for a long time and out side that the lifters could be stuck ?
  10. After changing the oil . I dont think it is a spun bearing . I think it is a lifter issue. Is there any videos out there regarding the repair of the lifters in these 8 motors? I am dreading taking the side covers off but if I have too I will so I van see which one it is .
  11. OK here is what I did I first used a 12 volt battery to crank the motor to UDC once I was able to see the mark on the flywheel I then re positioned the wires on the cap. Then the car fired right up. Unfortunately I think I have a rod knock. Oil pressure shows at 40 psi. I was thinking about doing an oil change and see what happens. Anyone have any other suggestions ? Also other thing I did for the motor to spin properly. I cleaned the ground that goes from the frame to the bell housing. Then I replaced the battery ground cable with a 2 gauge wire .
  12. Any one have the shop manual for the 1936 Pontiac 8 firing order?
  13. I was thinking that. When I look at the distributor it looks like it has not been pulled out at all. Can I loosen the collar and turn the rotor slightly?
  14. Update. I have cleaned the strap from engine to frame and also changed my negative cable to a new 2 gauge cable also cleaned frame. I am getting cranks faster now. Next question I have replaced the points,cap,rotor,wires and plugs. I am getting spark and fuel. The carburetor pops ever so often as I am cranking the motor. Is this possibly a points gap issue ?
  15. I have a few questions first does anyone know the correct replacement 6-volt battery. Next question is the battery positive ground or negative ground? I pulled a battery from one of my chevrolet six's and thought I would be able to get away with using the battery I already have but seems like it is cranking really slow. I understand that yes 6-volts crank slower than 12-volt but in my opinion it is just way to slow. I put new plugs wires,cap,rotor and points. Rebuilt carb new fuel pump and I am getting gas to carb but it just cranks and does not want to fire.
