finally got the car running but there isnt any oil at all comming up to the rocker arm. help please

Is this a rebuilt engine or a factory set-up recently "re-started"?
Confirm that the rocker arm shaft is in the correct position.
Below is the oil's 'pathway" to the rocker arms... follow it back to see if there is any blockage along the way.

If this a rebuilt engine the rear most cam bearing could be misaligned - Causing oil not to get to the top of the engine

Diagnosis is required. Remove the rocker shaft assembly (shaft, all bolts, all spacers, all rockers, all together). Remove all six spark plugs. Crank the engine as you watch the rearmost rocker shaft bolt hole. If you don't get a spurt of oil from that hole after some cranking, then oil's not reaching the cylinder head and you've got problems with clogged oil passages or misaligned rearmost cam bearing or improperly-drilled rear cam journal. Sadness and cussing. On the other hand, if you do get oil from the bolt hole, then all you have to do is figure out where the blockage is up top. Could be rocker shaft installed wrong way round (upside down and/or backwards), could be improper rearmost bolt.

Too many people who were born on third base actually believe they've hit a triple.

How LONG did you run the engine? It sometimes takes 30-60 sec of continuous running to get oil up there on a dry motor.

did the cam install easy or did you have some effort getting the rear journal to slip in?

could the cam not having a groove in it have anything to do with the oiling to the rockers?

If it doesn't have a groove, it should have a pair of intersecting holes drilled thru the rear journal.

it does. also a hydraulic cam

Not to bust your balls, but there have been several questions asked which you really should answer in order to get the best help here.

If this is a new engine build and you bought a hydraulic cam from Clifford with no groove on the rear journal then you need to remove the cam and have it grooved.

alright this is a rebuild engine. I pesronally did not build it and the guys that did have screwed us over and wont have anything to do with this engine. So were on our own. We have only put about 20 miles on the car so far. We noticed the oiling problem when we took the valve cover off. Took the back bolt completely out and only saw minimal amount of oil comming up to the rocker tube. when we took the cam out there was not a groove in the cam but instead there was 2 holes almost 180 degrees from each other. the rearmost cam bearing was in correctly. this cam is from Comp cams.

if you drove the car for 20min`s then it must be getting some oil or the top end would be fried.
So this is a hyd cam / lifters and the rear journal is grooved 360degs around?

Hello,
TOP has said already the cam has no groove.
Looks like the solution is to have the cam grooved and all should be well.
What has not been mentioned, is the back bolt - is the correct one (specifically for the hydro engine) been used? I seem to remember that I saw somewhere that they are specific to the hydro engines?

regards,Rod

When I did my build, I used a hydro cam from comp cams. The first one they sent me was ground on a solid blank (two holes like you described, instead of a groove). I sent it back to them. The next one they sent was on a hydro blank, but wasn't ground straight up.

Wouldn't really recommend comp cams at this point. I'd assume a machine shop could cut a groove for you - I didn't have a lathe when i got the wrong cam, or I would've tried cutting the groove myself.

Here is an option:
Install a fitting that leads into the lower - rear head bolt hole and use an external line to feed oil into the bolt hole.
Basically... by-pass the rear cam bearing & journal.
