Hi,



I built a 292 about a year ago, I noticed when I had the valve covers off tonight to set the valves that it was sort of dry in there. I pulled the distributor and primed the engine and no oil was going to the rockers, so I pulled the shafts and no oil was coming out of the hole in the head.



It had plenty of oil to the rockers when the engine was first primed before I started it for the first time.



The engine was running fine, good oil PSI, 75 when on the gas, no lifter noise. Only 200 miles if that.



When I rebuilt the engine I had a machine shop install new cam bearings, I also installed a new cam and lifters, I don't remember if the cam was grooved or cross drilled.



I'm sure it needs to come apart.



Any ideas what might have happened?



Thanks,



Ed

Is there no oil to either side ? When you prime at the distributor, I believe you need to turn it counter clockwise. Do you have normal oil pressure now?

Paul! You are correct.CC rotation.

  

If your camshaft is cross drilled, you may have to turn the engine to get oil to the top end.

Cam bearings made from soft material can shut off the oil supply to the topend in just a few hundred miles if the camshaft with the grooved center journal is being used.  These cam bearings get used simply because they cost about half what good quality cam bearings cost.  Priming the engine with the rocker arm assemblies off while slowly rotating the engine will help to verify if oil supply to the top end is existent or not.

Hi,



I have no oil to either side, I was turning the oil pump counter clockwise and I did have oil PSI at the gauge. I also tried cranking the engine over with a remote starter while I was priming the engine, still no oil at the heads.



I don't know if I have a grooved cam or not and my invoice from the machine shop does not say what cam bearings they used.



I guess I will pull the engine and see what is going on inside.



Thanks for you help,



Ed

Howdy,





I temporarily had a similar problem when I primed my newly rebuilt 292. I also have a cross-drilled camshaft. I turned the crank slowly while using a battery powered drill to turn the (CC) turn the pump.



When the holes finally lined up I got a LOT of oil at the rocker supply holes in the heads.



It's very possible that the cam bearing that allows oil to the heads has moved.





Regards,





Rick

Hi,

After some investigation, the cam bearings are part # F-9A, which are for a grooved cam, so I'm told.

The cam is cross drilled I think, I will have to pull it to be sure.

Could this be my problem?

Thanks,

Ed

I am about to start up my  292 and I don't understand the talk about priming the oil system !! Is there something i should be doing ? I have no idea what type of cam I have is there a easy way to determine without opening up the eng. Also would a 10 - 40 detergent oil be the best to use ! Brand ?

If you pull the distributor and use an extension and correct size socket and a power drill you can turn the pump CC  to pump oil all through the passages right up to the head prior to firing it up.Prevents dry start.I actually used the old oil pump driveshaft and a couple of parts from my nutdriver set and power dril  to prime the pump.I am using  Shell Rotella 15w40 on mine.If you do a search under "öil" there should several topics discussed previously.
