camshaft and oil pump
« on: April 02, 2013, 01:44:09 PM »

Hi guys.. I have a 2 questions. I just started my new rebuilt engine and it ran for about 5 seconds and crunch..What happened is the oil pump siezed and removed all the gear teeth from the camshaft and some from pump drive gear. >:(

The good news is the distributer drives off the oil pump so when the oil pump quits so does the engine

My 2 questions are Does anyone have a good cam they want to sell or trade for? and my second question. Is there a way to prime the pump and oil system before you start the engine. On old dodge engines we used to remove the dist drive shaft and you could drive the pump with an electric drill. I have also heard of packing the pump with thin grease to get started.

 The part I dont understand is when i took the pump out it would not turn. I took it apart and could find nothing wrong. I put it back together again and it works fine and the clearances are all in spec. ???

Has this happend to others and if so is it common?

The way I have primed engines in the past is take a old freon tank, put a hose on the bottom. [actually the top, you turn it upside down for liquid] with a hose barb with a threaded fitting that matches one of the oil galley plugs, take out the plug screw in the fitting, put oil in the tank, pressurize the tank with air and open the valve. If the block is clean it will flood the engine oil galleys with oil pre lubing everything.   Greg   
If it casts a shadow it can be restored

Henry,

David Yamulla had NOS camshafts and oil pumps for a fair price 1-2 years ago:
www.militaryvehiclesupply.net/

I installed a NOS oil pump. Was all stuck with old cosmoline, so I took it apart and cleaned it.
Now I am worried because I did not prime it before installing. Is there a big chance that it can
fail? Or can I use Greg“s tip to prime the system without having to take the pump out again?

Regards

Hinrik

Thanks Guys,

 I got in touch with Dave and he has a cam for me. I am giong to try the freon tank idea. That is a neat and simple idea. I am hoping that will also force oil into the pump and filter. I think if I can see pressure on the gauge everything should be filled.
