oil problems
Hi,
I'm a new kid on the block.
I have a '56 T bird and have just had the engine rebuilt. I have put in the oil and the EOS. I took out the spark plugs to help on first turn over stess. Everything turns well, water doesn't leak, gas gets to the carb but I get no oil pressure. Do I need to back pressure prime the oil pump? The shop manual does not say anything execpt turn the motor over and check the oil pressure.
Boy I don't want to take the oil pump off again!!!!!!!!!!!!!
Your advice would be greatly appreciated
Thanks............... Bob Fulton

312 oil problems
Hi all'
I have a 312 Y block out of a "rebuilding" 56 T bird. I had the engine rebuilt and am trying to turn it over for the first time. I have the oil, 20/50, and a quart of EOS added. The water dosen't leak, the gas gets to the carb and with out the plugs the motor turns easily.
The problem is that I don't get oil pressure and I was wondering if I need to back pressure prime the oil pump before oil pressure will develop. Boy I sure don't want to remove the oil pump again.
Any advice wwill be appreciated.
Thanks ...........Bob

oil pressure
Pull the distributor and spin the oil pump driveshaft till oil pressure comes up.
I have a homemade tool that I use. Just take a 1\4 in drive long extension and a 1\4 deep socket tape the socket to the extension and drive with a drill. Some times the oil pump pickup tube seal sucks air.
I hope this helps HOTWRENCH

Well, its been awhile since I worked on one of these so hopefully my memory is half good. You have the 312/352 engine as I remember. Don't pull the pump, pull the distributor. The pump is attached to the bottom of the dizzy via a six sided rod. As I remember, it is a 5/16" rod and a 5/16" socket glued on a 12" extension with nail polish will work. Put the socket combo on the rod, chuck the extension up in your variable speed reversing drill and turn that puppy until you have resistance. It will tax most 3/8' drills so get a grip. I would run it for about 30 seconds so that all of the journals are primed and have oil in them already at startup. I would also suggest running the drill in reverse for a short run to loosen the socket. DON'T attempt to pull it off of the rod, it needs to come off gently otherwise, you might be pulling the pump to get the socket off of the rod. Also, if it is the six sided rod, be sure to use a six point socket, do not use a twelve point. Your drill is going to be putting a bunch of torque on the socket.
And if my memory is correct, we'll both be surprized.

Every rebuilt engine I've ever installed, I just put it together and fired it up. I have never primed the bearings nor had a need to. It doesn't do any harm, that's for sure. As for your oil pressure ... first..are you using the stock guage? Is the wire hooked up to the sending unit and is the sending unit good? Try attaching a regular oil pressure guage directly to the engine, right beside where the wire attaches and it should tell your pressure. If the engine was rebuilt by a reputable engine shop, they should have put a new pump on it, rather than just clean and reinstall the old one....unless you knew it was putting out good oil pressure, for a fact, before the rebuild.
