chevy 235 oil lines & oil press gauge

hello, does anybody know about connecting the oil press gauge to the chevy 235 and where to connect the 2 lines to the oil filter, (does the line towards the front of the block go to the top of the filter or bottom. also is the line towards the back where the oil press gauge line connects ?) i really have no idea about the lubrication of this engine, any advice/critiscism greatly appreciated, thank you

There are 2 ports on the drivers side. One in the middle and one towards the rear of the block. The uppper line on the cannister will go to the rear port (where the oil press gauge connects. You will need a "T" fitting to connect the filter line and oil press line) The Bottom line goes to the middle port (which should have a plug and which you will remove in order to install the line)

 

thank you, that was very clear, & also i read somewhere that you should fill your oil pump before your 1st start up after rebuild to ensure immediate oil pressure, does this need to be done, also how would i go about doing that? thank you.

I like to fill the pump with molykote or another engine building cream and then prime the pump with a drill that has a flat head screwdriver end in it. This way you can build oil pressure before you even start anything.

 

Like the dude said above^^^^^^^^^^^^Drill and a flat "screwdriver type" tip. You will have to remove the distributor so you will need to get the engine at top dead center (TDC) and since the motor is not running yet (I ***ume) here's how I would do it:
Remove all the spark plugs (if they are on already) then I would squirt a little ATF (automatic transmission fluid) into each cylinder. Remove the valve cover (if it's on the motor) and then turn motor over, clockwise, by hand.
Watch the valve springs and when you see both exhaust and intake valve springs on the #1 cylinder (the first cylinder in front) decompress that means both valves are closed and #1 cylinder is on the compression stroke or TDC.
To double check, get a long straw or even a weed eater line (don't use anything hard like wire or coat hanger etc) and use it to see if you can feel the top of the piston (take care not to let the straw or line fall in) and if you can, you are pretty much at TDC.
You can turn the motor back or forth a little to try and get it as close as possible.
If you got that right, the rotor should be pointing at the #1 position on the distributor cap. So once that is done, pull the distributor out while watching how the rotor turns so when you put back the distributor it will go in the same way.
After you have primed the oil pump, you will have to turn the oil pump shaft (the slot) back to the position it was in when you removed the distributor.
It's not hard, it's just making certain that everything is in the right position and do not turn over the motor after the distributor has been removed. The oil shaft can be moved with a screwdriver by hand but if you turn over the motor, you will lose TDC and you will have to find it again.
All this ***uming the distributor is in. If not, just go straight to the drill and prime the pump.

 

thank you, just to make sure, 1 remove the diet with care to keep timing, 2 fill hole with oil, 3 prime the pump with screwdriver from where on the oil pump?

 

*distributer, not diet

 

thank you, just to make sure, 1 remove the diet with care to keep timing, 2 fill hole with oil, 3 prime the pump with screwdriver from where on the oil pump?

 

First make certain you fill the engine with motor oil (5 quarts if there's no oil) after the distributor is removed, get a flashlight and look inside the hole (where the distributor was) and there will be a shaft with a slot. That's where you use the drill and flat bit to turn the oil pump.
Remember to note the position of the slot before you prime the oil pump so the distributor can go back in exactly as it was removed.

 

And be sure to spin the shaft the right dirction Ot6herwise, you'll blow all the grease you packed into the pump back into the oil pan.

 

thanks guys ill probably be gettin to that 2morro, & hopefully the truck will be runnin on monday, thanks for the help
